What should wheat seed storage pay attention to?

What should be paid attention to in wheat seed storage? Please give guidance to wheat harvest in a hot and humid climate. Even after fully drying, if it is not managed properly after storage, it is still easy to absorb moisture and return to moisture, infestation, fever, mildew, and storage is more difficult, so it is necessary to master the key points of wheat seed storage technology. 1. Strictly control the storage period of wheat seeds depends on seed moisture, temperature and moisture resistance of storage equipment. According to local experiments, seed moisture is less than 12%. If moisture absorption and moisture return can be prevented, seeds can be stored for a long time without worms, mildew and germination rate. If moisture content is 13% and seed temperature is 30 ℃, the germination rate will decrease. The moisture content is 14-14.5%, and the seed temperature rises to 21-23 ℃. If it is not well managed, the possibility of mildew is very high; if the moisture is 16%, even if the seed temperature is 20 ℃, there is still a lot of mildew. Therefore, the moisture content of wheat during storage should be controlled below 10%, and the seed temperature should not exceed 25 ℃. 2. The heat resistance of wheat seeds stored in the warehouse after drying seeds is strong, which can be used to put the seeds into the warehouse while the seeds are hot, which can not only achieve the purpose of insecticidal, but also accelerate the wheat seeds to pass through eye rest. The specific methods are as follows: choose sunny weather to expose the wheat seeds so that the seed temperature reaches more than 46 ℃ degrees but not more than 52 ℃, then quickly store them in storage, add mulch, and seal the doors and windows. After keeping high temperature for 7-10 days, ventilation and cooling are carried out to make the seed temperature drop to close to the warehouse temperature, and then enter the conventional storage. The use of this method should grasp that the seed temperature should not be too high during the heat preservation period, the seed moisture must be less than 12%, and efforts should be made to prevent the bottom layer from condensation caused by the excessive temperature difference between the ground and the seeds; for dormant seeds, due to the weakening of heat resistance, this method is generally not suitable. 3. Use airtight anti-moisture storage according to the strong hygroscopicity of wheat seeds, the seeds should be tightly closed during storage to prevent external water vapor from entering the warehouse. in addition to airtight doors and windows, the seed pile can also be covered with cushions or gunny bags, which should be flat, tight, compacted and covered with 10-15cm drying pond ash to prevent both insects and moisture. For those with less dosage, the urns, pots, altars and vats with glazed inner and outer walls can be used to store the seeds, which are fully dried before storage, and pay attention to sealing after storage. It is more advantageous to put a layer of dry pond ash at the bottom of the container and on the surface of the seeds. The utensils can be safely stored for a long time in the house near the north shade or buried under the pool. 4. regular inspection of seeds during storage, the temperature, moisture and germination rate of seeds, as well as the temperature and humidity of the warehouse and the insects and molds should be checked regularly in order to find and deal with the problems in time.
