It can dry precipitation at the same time of high temperature, and the temperature is high in summer. On the one hand, the harvested wheat is dried to reduce the water content. On the other hand, drying the wheat barn at high temperature is also a good way. At the same time, it is also a good way to enter the barn at high temperature, such as 3-4 pm. The purpose of this is to kill pests and not give them living conditions.
2. Ventilation and cooling
During the storage of wheat, it is kept in a high-temperature sealed state for a long time, and the temperature in the granary rises due to the post-ripening, which leads to "sweating", that is, the increase of moisture, and finally leads to wheat mildew. Therefore, it is not ventilated regularly, and the wheat can be turned if conditions permit, so that the covered wheat can be exposed to the air to ensure the quality of the wheat.
3, pest control
In wheat storage, the main pests are wheat moth, corn weevil, Rhizoctonia solani and so on. Because of the high temperature in the barn, pests can easily multiply quickly. If not prevented in time, the quality of wheat will be seriously affected. At present, there are many methods to control pests, such as high temperature sealing, post-ripening hypoxia, low-dose fumigation and so on. Some pills are directly wrapped in cloth and buried in different positions of the wheat barn. No matter what method is used, the premise is to avoid pests.

Storage method of rice
Ensure the quality of stored rice: rice with large water content, many impurities and many imperfect grains is easy to be heated and moldy, and the storage is not durable.
Therefore, improving the quality of stored rice is the key to safe storage of rice. Generally, indica rice is below 13%, and japonica rice is below 14%. The less impurities and imperfect particles, the better. If the stored rice contains a lot of moisture and impurities, it should be dried or dried in time and screened to remove impurities.
Timely ventilation: Fresh rice should be ventilated and cooled in time because of its vigorous breathing, moderate grain temperature and high water content. Especially when the weather is cool in autumn, the temperature difference between inside and outside the grain pile is large. At this time, ventilation should be strengthened to deepen the grain surface, disperse the damp heat of the grain pile and prevent condensation. Mechanical ventilation can be used if conditions permit.
Low-temperature sealing: make full use of the cold and dry weather in winter for ventilation, so that the grain temperature will drop below 10℃ and the moisture content will fall within the safety standard. Before the temperature rises in spring, carry out shaft sealing to spend the summer safely.
