Harvesting seeds in winter is an important work that must be done to achieve the harvest in the coming year. Including anti-mildew, anti-pollution, anti-high temperature, anti-corrosion, anti-asphyxiation, anti-mixing, anti-smoking, pest control and other pests. Mildew: The key is to control the moisture contained in the seed itself. Cereal crop seed moisture content of 12% -13%, oil crop seeds 8% -9%, if the water content is too high, it is prone to mildew, especially peanuts, soybeans, corn and other oils and starch more Crop seeds should pay more attention. Anti-pollution: Seed storage should completely remove crop stems, weeds, sand, soil particles and other debris, and strictly sterilize the storage room and storage equipment to prevent the seeds from being contaminated during storage. Anti-high temperature: high temperature, strong seed respiration, will consume too much of their own storage of nutrients, reduce the germination rate, it is required that the temperature of the stored seeds is best around 10 °C, should not be placed near the stove on the seed. Anti-corrosion: Seeds cannot be stored in the same room as pesticides and chemical fertilizers. Because many pesticides and chemical fertilizers have strong volatility, the volatilized gases are extremely harmful to seed cells and embryos. Prevent suffocation: Seeds cannot be stored in plastic bags. Because the plastic bags are airtight, the seeds are forced to undergo anaerobic respiration inside the bags, producing toxic substances such as alcohol and organic acids, killing the embryos and causing the seeds to lose their germination ability. Mildew. Anti-mixing: The seeds of many crops are indistinguishable from ordinary foods. Little care is taken to produce mixed seeds and grains. It is easy to eat the seeds as food and cause great waste; it is also very easy to sow seeds as grain. , causing serious production cuts. Smoke prevention: The seeds are fumigated by the smoke for a long time, which will reduce the seed activity and weaken the germination rate. Therefore, the rooms where the flue gas (especially the flue gas and the flue gas) are large, such as the kitchen, cannot store the seeds, and the storage room should not be close to the kitchen. Insect Pests: Pests and rats not only directly eat the seeds, but also contaminate the seeds, degenerate the seeds and reduce the germination rate. Therefore, we must take measures to eliminate pests and rats.
