Since 1998, Shandong Liangyi Farm has been using the 2BQM-6A corn no-tillage precision seeder to introduce and promote new techniques in no-tillage machinery. Over the years, the farm has accumulated valuable experience, which is now summarized below.
First, to ensure that seed broadcasting is straight and uniform, making future field management easier, we have developed a special marker system. Permanent marker poles are placed in the field to guide the operation and maintain consistency in planting rows.
Second, during operation, foreign objects on the seed trays can cause the cylinder seedlings to be cut off, leading to suction issues or unexpected machine stoppages. To prevent this, operators must constantly monitor the seedlings and quickly remove any obstacles. This helps reduce downtime and ensures timely replanting when seeds are missed.
Third, seedling problems at the front of the machine often occur due to low engine throttle and slow rotation speed when starting, resulting in insufficient negative pressure for seed pickup. Therefore, it's essential to adjust the throttle properly before starting the machine.
Fourth, the issue of sparse plant spacing and low yield happens annually. The main causes include wide plant spacing, which can be corrected by increasing the number of seed holes and adjusting the sprocket ratio. Another factor is a low germination rate or insufficient seeding volume. Seed germination should exceed 90%, and pre-sowing preparation should include removing impurities and soaking the seeds. The recommended seeding rate is about 38 kg per hectare, with around 90,000 plants per hectare and 67,750–7,500 seedlings per hectare for optimal growth.
Fifth, to ensure a complete and efficient seeding process, we have established a specific workflow based on field conditions: first, a combine harvester cuts wheat straw into the field, followed by no-tillage sowing. Then, a straw return machine crushes the wheat stubble, herbicides are sprayed, and irrigation is applied using a sprinkler system. It's worth noting that chopped wheat stalks can be returned to the field. This practice not only covers the soil but also suppresses weed growth, keeps the soil loose, and helps retain moisture, improving drought resistance.
Lastly, common faults of this model include one row of seed disks failing to pick up seeds, usually due to low rotation speed or blockage from debris. The intermediate shaft may break if the belt is too tight. The knife may not be buried or may break due to wear or looseness. Additionally, disc openers may not rotate because of poor bearing conditions, requiring inspection, lubrication, or adjustment.
Through continuous observation and improvement, the farm has significantly enhanced the efficiency and effectiveness of no-tillage sowing, ensuring better crop yields and sustainable farming practices.
Natural Extracts
What is Natural Extracts?
Natural extracts are biologically active compounds or mixtures extracted from various plants and animals or microorganisms in nature. These extracts contain a wealth of chemicals, Such as alkaloids, flavonoids, saponins, polysaccharides, volatile oils, collagen, proteins, peptides, enzymes, antibodies, antibiotics, Amino Acids, nucleic acids, enzymes, monosaccharides, oligosaccharides, polysaccharides, glycoproteins, resins, colloids, lignin, vitamins, fats, oils, waxes, alkaloids, volatile oils, flavonoids, glycosides, phenylpropanoids, organic acids, phenols, quinones, steroids And antibiotics, etc.
Natural extracts have received attention in several fields due to their wide range of sources and potential multiple uses. They can be used in the pharmaceutical industry as ingredients in medicines or health supplements; In the cosmetic industry, as a functional or active ingredient to improve skin health; In the food industry, as an additive or flavoring agent to increase the nutritional value and taste of food; In addition, they have different applications in the fields of agriculture, environmental protection and scientific research.
Extraction methods include solvent extraction method, ultrasonic extraction method, microwave extraction method, enzyme extraction method, supercritical fluid extraction method and microwave assisted extraction method, etc. The choice of which method usually depends on the nature of the substance to be extracted and the target requirements of the final product. With the development of technology, the extraction process is continuously optimized to improve extraction efficiency, reduce environmental impact and maintain the biological activity of the extract.
