Seed selection: Before the seeds are put into storage, they should be subjected to wind selection or artificial screening to remove the impurities in the seeds and improve the storage purity of the seeds. At the same time, the surplus grain and debris in the warehouse should also be cleared, and the storage facilities should be sterilized to prevent transmission of diseases and insect pests and reduce undue losses.
Put a good moisture off: food crops should be controlled at 13-15 degrees, and oil crops at 8-13 degrees. Seed moisture content is too high, susceptible to frost damage, mildew, affect the germination rate.
Avoid mixing: Seeds stored in winter storage must be labeled with different crops, different varieties, and different grades, and stored separately. Do not store together with commodity grains and rations to avoid eating or selling. For small amounts of seed storage, do not use plastic bags. Because the plastic bag is airtight, it interferes with the normal breathing of the seeds. In severe cases, the seeds will suffocate and affect the survival and germination rate of the seeds.
Ventilation and drying: The cabinets and bags that hold the seeds should be above 40 cm above the ground in order to facilitate ventilation and prevent the seeds from getting damp.
Avoid cold and hot: The seeds stored outdoors can not be transferred to the warm room after the weather becomes cold. Otherwise, the germination rate of the seeds will be reduced due to sudden temperature changes.
Avoid smoke smoke: Seeds should not be placed in places that are often smoked. If the seeds are smoked for a long time, not only will the seed germination rate be reduced, but the growing seedlings will also be affected due to weak seed germination. Higher temperature in the bedroom.
Bogey and pesticides, chemical fertilizers with the release: Because pesticides and fertilizers are volatile and corrosive to varying degrees, have an impact on the physiology of the seeds, it can affect the seed germination rate.
Be diligently checked: Check for moisture, insects, rodents, mildew, etc. Identify problems and take preventive measures in time to ensure safe storage of seeds for winter.
