The latest points for attention in soybean storage

Soybean is one of the most important grain crops in China. Its protein content is very high. Many problems should be paid attention to during storage after harvest. Once the storage method is improper, it may lead to deterioration and mildew, which seriously affects the quality of soybean. So what do you have to watch out for when you reach storage? Let's get to know each other.

1. Fully dry

Soybeans are rich in protein and moisture and are easily denatured at high temperatures, so they should be dried and reduced in time after threshing. The moisture content of soybeans that need to be stored for a long time should not exceed 12.5%. The moisture content is too high, and it is easy to mildew during storage. It must be stored at low temperatures during storage. Especially after drying seeds. In order to avoid protein deterioration caused by high temperature accumulation, it must be spread out and cooled before storage. When warehousing, try to choose sunny dry weather, do not store in rainy and wet weather.

2. Seeds should not be piled too high

When soybean seeds are stored, the temperature is below 15 degrees. When the water content is lower than 12%, the stacking height is not easy to exceed 1.5 meters, so in order to avoid deterioration caused by heat accumulation, it is appropriate to pack 8 standard sacks high. If the temperature and humidity are higher than the above standard, the height of the stack should be reduced accordingly, and the spacing between stacks and walls should be arranged reasonably.

3. Timely ventilation

The moisture content of newly stored seeds is uneven, and the respiration is vigorous due to post-ripening. The moisture accumulation in soybean pile is more, and it is also the season when the temperature drops, so it is easy to appear dew. Therefore, in soybean storage for 3-4 weeks or so, timely ventilation, moisture dissipation and heat dissipation should be carried out to increase the storage resistance of soybeans.

4, should not be stored with pesticides and fertilizers

When storing soybeans, it should be dedicated to the warehouse. Chemical fertilizers or pesticides should not be stacked in the storage room to prevent toxic gases from entering the embryo after volatilization of chemical fertilizers and pesticides, resulting in decreased vigor and quality of soybean seeds.

5. Low temperature sealing

In winter storage, soybeans can be frozen and stored in a warm and airtight manner, which can not only isolate the influence of external temperature and humidity and pest infection, but also prevent oil immersion, red change, etc., which is conducive to maintaining the quality of soybeans.

The above is an introduction to soybean storage precautions. I hope it can help you. If you want to know more about it, please pay attention to us.
