Discussion on the application of straw decomposer in aquaculture
Keywords: straw decomposition aquaculture high efficiency
China is a big country in agriculture. The aquaculture industry occupies a large proportion in the agricultural economy. Guided by the scientific concept of development, promoting the construction of a new socialist countryside and realizing the peasants' pastoralists from poverty and getting rich are all inseparable from the vigorous development of the aquaculture industry. In the aquaculture industry, feed accounts for about 70% of the total culture cost. Solving the feed problem has always been the primary issue in the development of the aquaculture industry.
First, the development of straw feed is an inevitable choice for the development of aquaculture
The development of China's aquaculture industry has long been the traditional model, that is, cattle, sheep and other herbivorous animals rely mainly on natural grazing to obtain food resources directly from nature; pigs, chickens, and other monogastric animals are mainly fed with food, and humans Share food resources. Due to the lack of awareness and insufficient attention to environmental protection and ecological construction in China for a long time, many wrong policies such as excessive land reclamation, overcutting, overgrazing, etc. have resulted in serious ecological imbalances, severe environmental degradation, vegetation damage, grassland degradation, and land desertification. Soil erosion, drought, frequent floods and frequent sandstorms not only threaten human survival, but also pose a great threat to the development of the aquaculture industry. First, desertification in the mountains has no grass or pasture. Second, sharp decline in arable land, food shortages, and In recent years, they have had to rely on imported food to supplement the shortage of feed grains. In order to maintain ecological balance, protect human living environment, and achieve social and economic sustainable development, the country has introduced a series of policies, laws and regulations to stop the deterioration of the ecological environment and protect the natural environment, such as closing mountains for cultivation, returning farmland to grassland, and enclosing grass and grazing. , Development of livestock breeding and livestock breeding.
Closing mountains and grazing, grazing and grazing prohibited, and animal husbandry for grazing, grazing, grazing, and animal husbandry, which are grazing and feeding, and animal husbandry, and the key to the development of crops that can replace grass. High-value, low-cost new feed. To solve this problem, it is obviously not feasible to expand the area of ​​fodder grain planted or forage grass planting area according to traditional methods. The only way to solve this problem is to develop plant straw feed and develop straw aquaculture. This is the most economical, most practical and most feasible way to solve the feed problem under the conditions of limited land, food shortages, expensive forage, and high feed costs.
China's plant stalk resources are very rich. It can produce about 500 million tons of various types of straw each year, plus about 700 million tons of wool and grass. Among them, except that some of them are used for burning wood and some are not fully used as feed, most of them are discarded and incinerated, causing both waste of resources and serious environmental pollution. The development of straw feed can not only implement the national policy of reforming breeding methods and developing housing and livestock husbandry, but also can reduce waste cost, improve aquaculture efficiency, eliminate environmental pollution, and recover by turning waste into treasure. The multiple effects of ecological balance.
Botany theory tells us that plant stalks are made up of various nutrients and are natural resources rich in various nutritional values. First, all kinds of seeds germinate and form plants. Plants absorb nutrients for photosynthesis to produce glucose, then simple sugars are converted into amino acids, glucose and amino acids are gradually polymerized to form molecules, small molecules are then formed into macromolecules, and finally cellulose, lignin, Polymers such as crude protein and nitrogen-free extracts are polymerized into plants that contain various nutrients. Therefore, various plant stalks contain a lot of nutrients and energy, which can be a valuable feed resource. The inspection of the National Feed Quality Supervision and Inspection Department showed that the nutrient composition of the straw feed after biotechnological decomposition was significantly improved. Among them, crude protein was 13%, crude fat 5.38%, crude fiber 19.32%, salt 0.91%, ash 8.05%, calcium 0.386%, phosphorus 0.2228%, and total amino acids 11. 49%. The three limiting amino acids were: lysine 0.74%, cystine 0.2%, and methionine 0.16%. The corn that is sold as the main compound feed on the market generally contains only 8.6% crude protein, 3.4% crude fat, lysine 0.24%, cystine 0.16%, and methionine 0. 19%. It can be seen that the difference between the two nutrients is not great. The use of advanced technology to fully tap the nutritional potential of the straw is to fully meet the animal's needs for survival and growth, and effectively solve the contradiction between the development of animal husbandry and people's struggle for land and people's struggle for food.
From this we can see that starting from the actual national conditions, the development of straw feed is effective in realizing the aquaculture industry in China, from free-ranging nomadism to house-feeding, from grass-grass-based to straw-based, from natural breeding to scientific farming, and from traditional models. The only way to transfer the modern model is the inevitable choice for the development of China's aquaculture industry.
Second, the application of straw decomposition agent is the best choice for the development of straw feed
Since the development of straw feed is an inevitable choice for the development of aquaculture, how to develop straw feed has become a major scientific research topic in the aquaculture industry. For a long time, China's relevant scientific research departments at all levels have conducted a lot of research, developed and introduced a series of straw feed processing technology, such as ammoniation technology, alkalinization technology, silage technology, micro-storage technology, and promote the application in practice. Although these technologies have their own merits, they are generally only suitable for ruminant livestock and poultry, and they cannot be widely used for feeding. They also have large-scale investment, high technical requirements, long production cycle, complicated operations, and are difficult to preserve. , have not achieved the desired results.
In response to this problem, the National Model Workers, National Science and Technology Progress Special Award winners, National Advanced Workers in Science Popularization, National Outstanding Science and Technology Instructors, former Director of the High-Tech Application Institute of Agriculture and Animal Husbandry in Inner Mongolia Xingan League, and Inner Mongolia Shantang Farming and Animal Husbandry Wang Shantang, Honorary Chairman of Science and Technology Co., Ltd. conducted a special study. He has compared and carefully screened many related technologies to achieve the breakthrough of enzyme activation technology. After repeated research and experimentation, after eight years of efforts, he finally developed a new technology for the decomposition of plant straw - a bio-compound enzyme preparation, namely a straw decomposition agent. The problem of rapid decomposition and efficient transformation of straw feed.
The technology is based on the reverse reaction principle of biochemical reactions of crop straws. It uses biological complex enzymes, enzyme activators and carriers to synergistically decompose the macromolecules of straw, crude protein and cellulose, into small molecules until they are degraded into amino acids and glucose. Animals absorb directly. In this process, not only cellulose, cell walls, and cell mesenchyme are decomposed into nutrients, but also cell walls are destroyed and intracellular nutrients are released, eventually resulting in a significant increase in the absorption rate of straw feed. Not only herbivores such as cows and sheep can fully digest straw feeds, and pigs and other monogastric animals can also feed and digest straw feeds in large proportions. At the same time, because this technology can enhance endogenous enzyme activity and significantly optimize the digestive environment in livestock and poultry, complex feeds can also be fully digested, thereby achieving the goal of comprehensively improving feed conversion rate and reducing the cost of breeding.
Compared with various types of fermentation technologies, what are the different characteristics and characteristics of straw decomposition? It can be seen from the comparison that in addition to the common functions of degrading straw nutrition and improving feed conversion rate, the two still have many differences and differences.
The first is that the substance of action is different. The role of straw fermentation technology is living bacteria, the role of straw decomposition agent is active compound enzyme; straw fermentation technology production of feed is acidic feed, long-term feeding is easy to form acidosis, straw decomposition agent feed is a neutral feed, Not acid and alkali, long-term use without any side effects. And straw decomposition agent itself does not contain any hormones, antibiotics, is pure green, environmental protection, pollution-free products, livestock and poultry long-term feeding has no toxic side effects.
Followed by different mechanisms of action. The degradation of animal feed by fermentation technology can only be performed outside the animal and cannot be continued in the animal; it can only act on roughage, but not on the concentrate; it can only be applied to ruminants, but not to a large proportion of monogastric animals. Only the feed can be degraded, and the animal's digestive environment cannot be improved. The decomposition of animal feed by straw decomposition technology can not only be performed in vitro but also can be continued in animals. Not only can the full degradation of roughage, but also the full degradation of concentrated feed can be achieved; not only the effect of the feeding of ruminants will be better, Moreover, monogastric animals can also feed a large proportion of straw feed; not only can the overall state of feed be improved, but also the animal's digestive environment can be fully improved.
The third is different application conditions. Fermentation technology requires higher temperatures (above 20°C), higher nutrition (supplemented nutrients), larger scale (fermentation ponds) and longer time (around one week), high conditions, large investment, and difficult operation; and straw decomposition technology No need for high temperature (above 0°C), without supplemental nutrition, the scale can be varied, the action time is short (2 hours in summer and 4-6 hours in winter), and the decomposition conditions are low (cement surface, large cylinder, large Pot can be), easy to operate, "powder a powder, mix a mix, can be fed a bowl."
The fourth is that the effect is different. The scope of application of fermentation technology is limited, economic efficiency and product quality can not achieve the ideal realm; and the application of straw decomposition technology to engage in culture, generally can achieve the effect of halving the cost and double the benefit, and the input-output ratio can reach 1:5 or more. Poultry products generally meet the pollution-free product quality standards.
Obviously, straw decomposition technology has many obvious advantages for straw fermentation technology. Neither technique can be confused, and straw decomposition technology is mistaken for fermentation technology; neither can it be the same for both, mistaking the function, effect and effect of straw decomposer and straw starter.
The method of using the straw decomposing agent: First, the straw is crushed and fed to ruminants such as cattle and sheep. The straw is crushed to a length of 1-3 cm, and the straw is fed into a single stomach animal such as a pig and a chicken, and the straw is crushed into a shape of a straw. The straw decomposer was hydrolyzed and then mixed well with the crushed straw powder, sealed at room temperature for 2 hours, and then decomposed in winter at temperatures above 0°C for 4-6 hours before feeding.
The outstanding characteristics of straw decomposing agent in application show that it is different from other straw processing techniques. It shows that straw decomposing technology is the most advanced, most advantageous and most popular straw processing technology in many straw processing technologies. . The research, experiment and demonstration of straw decomposition technology has now been going on for nine years and has received extensive attention from the relevant national authorities. During the research process, the former Xing'an League Agricultural and Animal Husbandry High-Tech Application Research Institute cooperated with the Ulanhot City Edible Fungi Research Institute of Xing'an League to include the research of the project in the National Spark Program. The project was “Efficient Transformation and Utilization of Straw and Industrial Developmentâ€. Approval number: No. 350 (2001) of the State Administration of Industry, project number 2001EA64008. The technical achievements were exchanged at the 2003 China Association for Science and Technology Academic Annual Meeting. Professor Liu Defu, a renowned biochemistry expert and professor of the Department of Biochemistry and Molecular Biology of Peking University, commented: “This technological breakthrough ranks the leading domestic level.†To identify this project, In April 2004, the Ministry of Agriculture Feed Industry Association dispatched an expert team to conduct an inspection. After the inspection, it was considered that the results of the application of the results are true, especially for the outlying areas and small and medium-sized farmers particularly worthy of promotion, it is recommended to operate the market as soon as possible, complete access to market procedures, promotion in the country. In August 2004, the scientific research achievement of straw decomposer won the "Major Innovation Achievement Award for the "Economic and Technological Innovation Project of the Workers in Inner Mongolia Autonomous Region" Activity in the "Economic and Technological Innovation Project" of the employees of the Inner Mongolia Autonomous Region. In March 2006, China Rural Technical Association issued a notice to promote Shantang brand straw decomposer as a key project for science and technology beneficial farmers.
As straw decomposition technology is more innovative, advanced and practical than other straw processing technologies, the use of straw decomposer to develop straw feed is the best choice for the development of aquaculture.
Third, the effect of straw decomposer in aquaculture practice
The application of straw decomposition technology in the past ten years has generally created the magical effect of increasing the breeding efficiency and improving the quality of livestock products. It has been widely recognized and widely praised by users. It is technically fast and easy to operate.
Rich source of raw materials. All kinds of plant straws, root stalks, thatch, leaves, rice bran, etc. can be decomposed into feeds, and at the same time, it can also decompose full feed concentrates and other concentrated feeds. Feeding animals achieves the desired effect.
Advanced product technology
Wide range of applications
(A) A substantial increase in digestion and absorption rate. Regardless of roughage or concentrate feed, digestibility can be increased by about 30%, digestion and absorption will be good, feed intake will gradually reduce, generally can reduce 20-30%, which is mainly reflected in the reduction of fecal volume by about one-third, No odor, shiny pile, delicate fiber.
(b) Significantly reduce feed costs. Feed costs can generally be reduced by 30-50%. The specific experimental effect is that feeding cows with straw decomposer can save the cost of feed for more than 2 yuan per day and save more than 500 yuan in feed cost per year. The use of straw decomposer to raise pigs can save pigs per head per day. The feed cost is more than 1.5 yuan. In a slaughter period, the cost of feed is saved at least 150 yuan. With the straw decomposer for raising sheep, raising geese, raising chickens, and raising ducks, the cost of feed can be reduced by more than 30% compared with conventional farming methods.
(3) Significantly increase the output of meat, milk and eggs. The application of straw decomposer to feed livestock and poultry can generally increase the production of meat and eggs by about 10%. Dairy cows can increase milk by 2-5 pounds per day and 800-1,500 pounds per year.
(d) increase economic efficiency. The use of straw decomposer feeds livestock and poultry, achieves straw substitutes and substitutes grass, improves feed conversion rate, reduces feeding volume, increases meat, milk, and egg production, thereby achieving a significant reduction in feed costs, increasing production, and increasing income. Output ratio up to 1:5 or more. The specific effect is: a cow needs to use 10 kg of straw decomposing agent a year, 300 yuan for the whole year, and the output is that a cow can increase the annual savings of 1,000-1,500 yuan, after deducting straw decomposition agent input, the average per head Cows increase at least 700-1,200 yuan each year.
With straw decomposer for rearing pigs, only one kilogram of straw decomposer is required for each pig at the time of slaughter, which is 30 yuan, and the output is more than 150 yuan. Each pig can increase income by at least 100 yuan; according to the calculation of the farmer One hectare of corn stalks can raise 5 finishing pigs with an income of more than 1,500 yuan. Farmers and herdsmen living in poverty-stricken areas can earn more than 3,000 yuan if they use two acres of straw to raise pigs, and they can get rid of poverty in that year.
Raise sheep. Each sheep needs to use 1 kg of straw decomposing agent per year, which is 30 yuan; and the use of straw decomposer to save grass, save materials, accelerate fattening, each sheep can increase income by at least 100 yuan.
Goose breeding, duck raising and chicken raising are calculated according to three months of goose, one-and-a-half months for ducks and chickens in each slaughter period. The investment amounts are only 3 yuan, one yuan and 0.4 yuan, respectively, while the output can reach 15 yuan and 5 yuan. More than 1 yuan, 30-50% more efficient than conventional breeding. Specific input and output can be seen in the following table:

(C) significantly improve the quality of livestock and poultry products. The straw decomposer has no antibiotics, no hormones, no toxicity, no harm, and no side effects. It is a pure green, environmentally friendly animal health product. The meat, eggs, milk and other products produced by straw decomposer feeding livestock and poultry can completely meet the pollution-free quality standards. Henan Detai Agriculture and Animal Husbandry Technology Co., Ltd. sent fattening pigs fed with straw decomposing agent decomposed by straw decomposing agent to the Quality and Safety Supervision and Inspection Center of Livestock and Poultry Product of the Ministry of Agriculture for testing according to the “Pollution-free Food Pork†standard. All 18 indexes tested were qualified. , Confirm that pork produced from fattening pigs fed with straw decomposer is pollution-free pork. The dairy farmers in Xing'an League, Inner Mongolia, will use the straw decomposer to decompose the milk produced by straw-raising cows and send them to the technical supervision department for testing. Milk protein and milk fat content are higher than the national technical standards by more than 15%, and no toxicity indicators are detected. Practice has shown that the use of straw decomposer for feeding livestock and poultry, can completely produce pollution-free meat products.
(IV) Quickly realize poverty alleviation by farmers and herdsmen According to the practice of aquaculture demonstration households, corn and straw in one mu of land can be used for raising pigs, and 5 finishing pigs can be raised for income of more than 1,500 yuan, while sales of corn can only earn 500 yuan. Around, the aquaculture efficiency per mu is three times that of planting. If straw is used as a decomposer to develop pigs in impoverished areas, the per capita farmland will be 10 pigs per capita, and the annual income will be more than 3,000 yuan per person. Cow, goose
(5) turning waste into treasure, multiplying land,
Eliminating pollution and purifying the environment
According to the statistics of a large number of experimental data, the application of straw decomposer to feed straw and livestock, the input-output ratio is generally up to:
The use of straw decomposer for the development of straw feed for livestock and poultry, as well as significantly increased disease resistance of livestock and poultry, the body's nutritional balance, health of the reproductive system, female reproductive success, high animal survival rate significantly. At the same time, since the straw decomposer does not have any hormones or antibiotics, and the long-term use of livestock and poultry has no toxic side effects, it can ensure excellent quality of meat, eggs and milk.
The third is to improve the quality of livestock products In addition to the technical decomposition of straw decomposition agent, 2-6 hours to complete the decomposition process; production is simple, powder-powder, mixed with a mixture, can be fed with a meal; digestion is adequate, The feed conversion rate can be increased by more than 30%; it is widely used, and the outstanding characteristics of all kinds of livestock and poultry can also be provided.
Straw decomposition agent decomposition of straw quickly, only 2-6 hours, full digestion, whether rough feed, concentrate conversion rate can be increased by more than 30%.
The use of straw decomposer is very simple and suitable for all farmers. The straw is first crushed and fed to ruminants such as cattle and sheep. The straw is crushed to a length of 1-3 cm and fed to single stomach animals such as pigs and chickens. The straw decomposer is opened with water and then mixed with the comminuted straw powder. After being sealed at room temperature for 2 hours, the mixture can be fed with the compound feed. In the winter, the temperature is only decomposed for 4-6 hours under the condition of 0°C or more. Feeding. Straw processing time is the shortest in the world today. The so-called “mixing, mixing, and simmering†will be able to feed. It is very easy to use and it is easy for farmers to grasp.
Using straw decomposer to feed livestock and poultry, the feed cost can generally be reduced by 30-50%, and the input-output ratio can generally reach 1:5 or more. The source of raw materials is widely used. Plant stalks, root mash, feed, thatch, leaves, rice bran, etc. can all be decomposed into feedstuffs and fed to livestock and poultry to achieve ideal results.
The straw decomposer has no antibiotics, no hormones, no toxicity, no harm, and no side effects. It is a pure green, environmentally friendly animal health product. The meat, eggs, milk and other products produced by straw decomposer feeding livestock and poultry can completely meet the pollution-free quality standards. Henan Detai Agriculture and Animal Husbandry Technology Co., Ltd. sent fattening pigs fed with straw decomposing agent decomposed by straw decomposing agent to the Quality and Safety Supervision and Inspection Center of Livestock and Poultry Product of the Ministry of Agriculture for testing according to the “Pollution-free Food Pork†standard. All 18 indexes tested were qualified. , Confirm that pigs for finishing pigs fed with straw decomposer are pollution-free pork. The dairy farmers in Xing'an League of Inner Mongolia will use the straw decomposer to decompose the straw-produced milk produced by milk cows and send it to the technical supervision department for testing. Milk protein and milk fat percentages are higher than the national standard by more than 15%, and no toxicity indicators are detected. Practice has shown that products that use straw decomposition agents to feed livestock and poultry are pollution-free products.
A straw-decomposing agent is used to feed a cow with a demand of about 10 kilograms a year, and a year-old cow can increase revenue by more than 1,000 yuan.
With the straw decomposer to raise pigs, according to the 6-month slaughter period, the average amount of straw decomposing agent per pig is only about 1 kg, each pig can save 30-50% of the cost of feed, a feed period can save at least 100 feed costs -150 yuan.
With a straw decomposer to raise sheep, each sheep needs about 1 kilogram per year, and the straw decomposer is used to save grass and materials and accelerate fattening. At least 100 yuan can be added in the whole year. Goose breeding, chicken breeding, and duck straw decomposer are more than 30-50% more efficient than conventional breeding.
Fourth, the prospect of market development of straw decomposition agent
The use of straw decomposer to make straw feed has a rich source of raw materials: almost all non-toxic, odorless plant stalks, thatch, leaves, crops, etc. can be used; the market is widely used, almost all kinds of livestock and poultry can be used for feeding; Urgent needs of users, almost all of the country's urban and rural aquaculture industry, are exploring and seeking ways to develop straw feed to aquaculture and methods. Since the reform and opening up, the aquaculture industry in China has developed rapidly and it has a considerable scale. By the end of 2002, the number of cattle, sheep, and pigs in the country had reached 910 million heads (only), of which 130 million were cattle, 460 million were pigs, and 320 million were sheep. In addition, there are horses, donkeys, deer, rabbits, geese, chickens, ducks, etc. All these livestock and poultry can feed straw feeds developed with straw decomposers.
The market demand for straw decomposer is based on 10 kg, 1 kg, and 2 kg per cow (head), sheep, and pig per year. The total market demand for decomposer in the year is 2.54 million tons. The market development rate is 10%, the annual demand is 254,000 tons, and the annual production value can reach 7.6 billion yuan. According to the input-output ratio of 1:5, it can create social economic benefits of 38 billion yuan. It can be seen that the market development prospects are broad and attractive.
The development of straw decomposer not only has huge economic benefits, but its social benefits are particularly inestimable:
1, eliminate pollution, purify the environment. For a long time, straw has been unable to be handled in many places and it has often been burned to pollute the environment. Applying this technology to convert straw into feed reduces environmental pollution and reduces the potential for fire hazards. Therefore, the project has very good environmental benefits.
2. Protect grasslands and restore ecology. The development of straw decomposing agent makes a large amount of straw into feed, instead of forage grass, reducing the pressure on the grassland, which can effectively protect the grassland and restore a good natural ecology.
3, the development of aquaculture, grass-saving province. The promotion of straw decomposer can effectively solve the contradiction between people and livestock for grain, food and grass, and save a lot of food and forage. Only using 470 million heads of stray pigs for feeding straw decomposer feeds can save 1,88 billion kilograms of food per year, enough for a population of 376 million people a year.
4, turn waste into treasure, rich people. The issue of “three rural issues†in China is a major issue in the construction of rural well-to-do society. At present, a considerable number of rural areas are still in poverty. The use of straw to develop aquaculture has opened up a convenient and feasible way for poverty-stricken areas in China's poor areas to become rich.
5, abdomen return to land, conservation of land. The application of this technology has enabled the national project to return straw to the abdomen to reduce the input and pollution of chemical fertilizers. This has effectively protected the land, greatly reduced the cost of agricultural production, and improved the economic benefits of the breeding industry.
6, the rise of a business, multi-industry follow-up. The industrialization of the straw decomposing agent project has a tremendous driving and promoting effect on the industrial development of machinery manufacturing, meat processing, and raw material production, thereby promoting the development of the national economy.
7, provide manure source, develop energy. Biogas is a new energy source in rural areas. The development and utilization of this new technology requires sufficient manure sources. Straw decomposer feeding livestock and poultry can provide sufficient manure source for the development of biogas. Therefore, the promotion of straw decomposer is beneficial to the development of rural new energy, and at the same time, it can effectively realize the virtuous cycle of planting and breeding.
8, widen the road, extensive employment. The development of straw decomposers will surely form an industry. All aspects of this industry need human resources to build. Therefore, it can provide new employment opportunities for the community. Every year, a large number of college and technical secondary school graduates in our country have to work; the bankruptcy of enterprises, the laid-off workers must be re-employed; a large number of annual turnover, veterans must also be re-employed; rural surplus labor forces have to leave their hometowns to seek employment; there are disabled needs Employment and so on. The above-mentioned employment problems are closely related to the government and are difficult to solve. The development of straw decomposition agents and the formation of industrialization trends can absorb a large number of people from all walks of life in the society, providing them with the road to employment and life. With an annual output of 366,000 tons of straw decomposer and industrialization, 366 small-scale plants with an annual output of 1,000 tons, 4,390 employees, 5,000 marketing staff, 500,000 new farmers, and a total of employment About 1 million people.
The above analysis tells us that the development of straw decomposition agents and the development trend of industrialization, the economic benefits are enormous, and the social benefits are also incalculable. In order to quickly transform and promote this project, the company has taken various measures to cultivate the market. Since 2003, various media across the country have conducted extensive publicity. The Central People's Broadcasting Station has broadcast more than 10 popular science lectures, and CCTV has reported that county-level television stations in more than 1,000 counties nationwide have conducted special radio broadcasts. Economic Daily Several dozens of newspapers, such as the “peasant daily†and “science and technology dailyâ€, were reported, and dozens of websites such as People’s Daily and Xinhua.com have been publicized. The company has established more than 3,000 test demonstration sites throughout the country; all over the country require agents to have telephone calls and letters. The company is building a straw decomposition agent promotion network. In September 2004, the straw decomposition agent has completed all access market procedures and has begun to formally promote the country. [Executive Standard: Q/NSTN001-2004, Product Approval Number: Mongolian Feed (Pre) Word (2004) 351002, Production License Number: Feeding (2004) 3922]. Agricultural Technology Association
Biostalk decomposition technology is both innovative and practical technology. At present, we are heading towards the country with the spark of prairie fire. This technology not only has great application and promotion value in the aquaculture industry, but also has a broad prospect for development and application in the winemaking industry, papermaking industry, edible fungi industry, and organic fertilizer industry. At present, the company has developed a special straw decomposer in the edible fungi industry – Mushroom's raw material decomposer, which will soon be put into production. The application of new technology for the decomposition of biological straw in other fields is also under study. It can be foreseen that technological breakthroughs in these areas of research will inevitably lead to a wider range of technological progress and economic growth, so as to promote the faster development of China's national economy and accelerate the process of building a well-to-do society in rural China.
