Peanut Seed Storage Methods and Key Technical Points

First, before storage, the seeds must be thoroughly sun-dried so that the seed moisture content drops below 8%. According to experiments, when the seed moisture content is below 8%, storage is very safe, and even at -25°C, germination capacity is not affected. When the seed moisture content is above 10%, respiration increases, releasing a large amount of heat energy, which easily causes the seeds to become moldy, deteriorate, and become infested with insects.

Second, the seed purity must be improved by removing impurities and immature, shriveled pods, releasing a large amount of heat energy, which easily causes the seeds to become moldy, deteriorate, and become infested with insects.

Third, the storage site must be strictly disinfected and sterilized, kept moisture-proof, and the warehouse must be kept ventilated and dry.

Fourth, woven bags and gunny bags are better as storage containers, and avoid using airtight plastic bags for storage. Storing seeds in plastic bags easily causes poor air circulation, causing the seeds to undergo anaerobic respiration and poisoning the seed embryo; at the same time, the moisture and heat produced by respiration are not easily dissipated, causing the seeds to heat up and become moldy.

Fifth, peanuts must not be stored in the same warehouse as pesticides and chemical fertilizers. Many pesticides and chemical fertilizers have a certain volatility and corrosiveness, and have damaging effects on seed cells and seed embryos.

Sixth, during storage, attention must be paid to frequent inspections to see whether the seeds have become damp, been damaged by insects or rats, and whether the seed germination vigor and germination rate have decreased. If problems are found, handle them promptly to ensure the safe storage of peanut seeds.
