How to deal with soybean drug damage?

In the process of soybean growth, it is inevitable to use pesticides and fertilizers, but it is easy to cause drug damage when lack of experience, so how to do soybean drug damage?

I. growth habits of soybean

Soybean is a kind of crop of Leguminosae and soybean genus, also known as soybean, soybean, etc., mainly distributed in China, the United States, Brazil and other countries, the planting area in China is also relatively large, is a more important crop.

Soybean is a crop that likes to grow in a warm environment. Seeds begin to germinate at 10-12 ℃ and grow best at 15-20 ℃. It is best to keep the temperature at 20-28 ℃ during the flowering and podding period, because the podding of soybean will be delayed at low temperature, so it is best not to be too low, and the soybean can not blossom below 14 ℃.

However, if the temperature is too high, the plants will end their growth ahead of time, and it is best to control the temperature of soybean growth. Seed germination requires more moisture, and the flowering period requires soil water content of 70% Mel. 80%, otherwise the bud shedding rate will increase. Soybean absorbs less than 15% of the total fertilizer before flowering, while the flowering and podding stage accounts for more than 80% of the total fertilizer absorption.

Second, what about the drug damage caused by soybeans?

1. Some plant growth regulators can be sprayed to alleviate mild drug damage to a certain extent.

2. When there are symptoms of drug damage such as yellowing of soybean, fertilizer can also be applied to alleviate the drug damage.

3. If it is caused by soil medicament, it can be treated by ploughing and other methods to reduce the residue.

How to store soybeans

Because soybean is a kind of crop with strong hygroscopicity and easy mildew, it must be stored in a cool and dry place at ordinary times, and it is best to keep it sealed to avoid mildew. Soybean deterioration is characterized by soft soybean grains, gray seed coat, whitening, slight peculiar smell, and then soybean grain expansion, deformation, navel redness, broken grains appear colonies, and the quality deteriorates sharply.

If the above situation occurs in soybeans, slightly put the soybeans in the sun for exposure, and then continue to use, if the situation is more serious, it is best not to use it again.
