(B) The characteristics of the diamond water chestnut is an annual herb floating aquatic plants, long stems, strong adaptability, living in subsoil soft ponds, lakes, rivers, canals, and deep water lake fields and other waters. Water chestnuts begin to sprout at temperatures above 13°C and are not tolerant of frost and are suitable for growth in waters with a depth of about 2 metres. It usually takes about 150 days from seed germination to fruit ripening.
(3) Method of planting Before planting the water chestnut, remove wild plants such as pond grass and moss. Seed before and after Qingming. Before planting, seedlings were placed in bamboo rafts and they were germinated in shallow ponds. The buds grew to 1-1.5 cm. The method of sowing seeds is better, with a spacing of 2 meters. Bamboo sticks are inserted at both ends of the plant line as a marker. One person will plow and one person sows. The amount of seeds used per 0.067 hectare is 23-25 ​​kg and about 1200 strains.
(d) Fish rearing in the ponds of the seedlings can be combined with a fish rearing model. Stocking species, except for grass carp and alfalfa, alfalfa, cockroach, cockroach, cockroach, etc. can be stocked. Because grass carp will eat Ling Ye, Ling Ling. There is arch mud habit. For each 0.067 hectare of water, 15 kg of stocked fish are stocked, about 400 of which are stocked with 45%, 30%, 15%, and 10%. Before the fish species is under the pond, immerse the fish body with 2%-4% saline for 4-5 minutes to prevent diseases.
(v) Pond Management
1. Fertilization: Divided into base fertilizer and top dressing. Due to the thicker silt in the seedling pond and fertile soil, no base fertilizer is generally required. If the sludge is shallow and the soil is thin, 3,000-4,000 kg of Shitang mud per 0.067 hectares will be required as base fertilizer. In the flowering stage of Lingshen, foliar spraying of 1%-2% phosphorus and potassium fertilizers was sprayed once every 7 days for a total of 2-3 treatments. Fertilizer can be manure-based, but it must be fermented into the pond. Application of organic fertilizer, depending on the status of water, such as thin, appropriate to grasp the amount of fertilizer. General thin water more fertilization, fertilizer and water less or not applied. The transparency of the pool is better to keep 25-30 cm.
2. Adjust water quality. Ponds that use manure as their main source should regularly replenish new water, 1-2 times per month, and add 20-30 cm of fresh water each time.
3. Adjust the pH. After quicklime is used, the whole pool is splashed with water. It is used 1-2 times a month and each time it is 10kg per 0.067 hectare.
4. Always visit the pond, observe the fish's activity, and do a good job of preventing flooding, disease prevention, and theft prevention.
(6) Harvesting is usually started in September and picked up every 7 days or so. It was picked in late October. At the same time of picking the ridge, according to the following year's planting production plan, the large-grained and old-maturing linguistics were selected. The seed preservation method is to place the seedlings in bamboo rafts. The bamboo rafts are suspended in the water and bamboo scaffolds without being exposed on the surface of the water, so that they cannot be rotted.
Activated carbon is a material which commonly used in air purification, mainly used to adsorb the few toxic gases, ammonia, formaldehyde and benzene without pollution,toxic and side effects. The effect of activated carbon
1.Indoor air purification. After the bedroom decoration, we can place activated carbon to absorb harmful gases,you can also put it in toilet to remove odors.
2. Furniture purification. Put the activated carbon into the closet to remove strange smell, humidification and mildew; put it into the shoes which can remove odors and germs; put it into the refrigerator to prevent food cross-taste and pollution that keep food fresh .
3.Floor protection. When the floor is paved with activated carbon directly under the floor which can go to taste humidification, mildew and pest control, but also to avoid the floor deformation.
4. Active carbon mattress. The mattress added activated carbon can absorb moisture, remove sweat and keep the bed clean; secondly, it can improve the health function of lumbar muscle strain for the elderly. Because it has infrared radiation with a certain temperature, human body has health effect when long-term use.
5.Put activated carbon into the car, it adsorb harmful gas inside the car and remove peculiar smell.
6. Used for pet cleaning to adsorb odor which is non-toxic, no side effects, and no harm.
7. Put the activated carbon next to the appliance to prevent electromagnetic damage.
8. Activated carbon can be placed in the fish tank and swimming pool for disinfection and purification of water.
