Storage methods of Peanut Seeds
First, the seeds should be fully dried before storage, so that the water content of the seeds is reduced to less than 8%. According to the experiment, when the seed water content is less than 8%, the storage is very safe, even at-25 ℃, it does not affect the germination power. When the water content of the seed is more than 10%, the respiration is enhanced and a large amount of heat energy is released, which is easy to make the seed mildew and deteriorate and give birth to insects.
Second, it is necessary to improve the cleanliness of seeds, remove impurities and unmature blighted fruits, and release a large amount of heat energy, which is easy to make the seeds mildew and deteriorate and produce insects.
Third, the storage site should be strictly sterilized, moistureproof, and keep the warehouse ventilated and dry.
Fourth, it is better to use woven bags and gunny bags for storage appliances, and avoid using airtight plastic bags for storage. The storage of seeds in plastic bags is easy to cause poor air circulation, which makes the seeds breathe without oxygen, and the embryos are poisoned. At the same time, the moisture and heat produced by respiration are not easy to be distributed, which makes the seeds hot and moldy.
Fifth, peanuts can not be stored in the same warehouse with pesticides and chemical fertilizers, many pesticides and fertilizers are volatile and corrosive, which can damage the cells and embryos of seeds.
Sixth, during storage, we should pay attention to check frequently to see whether the seeds are damaged by moisture, insects and rats, as well as whether the seed germination potential and germination rate are reduced, and find problems and deal with them in time to ensure the safe storage of peanut seeds.
