What to do after the flood of edamame

The arrival of summer is also accompanied by the rainy season, and there have been continuous torrential rains in many parts of the south. And summer is also the planting season for edamame beans, which are the least resistant to waterlogging. Waterlogging can lead to root rot and slow growth. What should I do after the edamame flood? How can we not reduce the production of edamame beans? Let's take a look at it.

1. Timely drainage

Because of the flood caused by the rainstorm, the water should be discharged from the planting area immediately after the rainstorm stops to avoid further waterlogging. Dig out the soil in the field border, make sure that there is no excess mud to block the discharge of stagnant water in the three ditches of field border, perimeter ditch and waist ditch, improve the drainage efficiency between the fields, discharge the excess water in the field as soon as possible, and reduce the water content in the soil after removing the stagnant water.

2. Topdressing in time

After the waterlogging in the edamame field, the waterlogging is very easy to take away the fertilizer and nutrients in the soil, resulting in a sharp decline in soil quality. Therefore, the plant should be sprayed with quick-acting fertilizer immediately after the flood, so as to restore the growth rate of edamame as soon as possible and promote the transformation of seedling condition. After the excess water in the land is discharged, urea is applied per mu of land. If there are stiff seedlings, you can spray some foliar fertilizer or regulators, such as potassium dihydrogen phosphate, which can promote the recovery of rigid seedlings and make them begin to grow normally.

3. Ploughing and weeding

After the waterlogging has been removed, the soybeans should be intertilled, because intertillage can quickly reduce the moisture in the soil and enhance the ventilation and permeability of the soil. Promote the root growth of edamame, remove excess weeds in the field, so as to prevent weeds from competing with plants for nutrients. Generally speaking, at least three times of intertillage should be carried out after waterlogging, and the lodging should be avoided according to the growth of edamame beans.

4. Prevention and control of diseases

In case of high temperature and high humidity after rainstorm, edamame bean is very easy to produce many germs and insect pests, such as rust and aphids. Therefore, in order to prevent or control these diseases, more pesticides should be sprayed for pre-control, such as using strychnine to control rust, imidacloprid to control aphids, enemy killing to control heart-eating insects and so on. According to the use of different agents according to different diseases, do not use too much, it is harmful to the plant.

5. Chemical control and anti-prosperity

Continuous torrential rain will make edamame beans lack of light, resulting in overgrowth of plants, only blossom but no fruit, and the top fruit can not receive nutrition. Therefore, some chemical control agents can be sprayed at the flowering and fruiting stage of edamame to control the overgrowth of the plant. The growth of edamame beans not only can not increase the yield, but will only consume more fertilizer and water.

The above is the specific treatment of edamame after the flood. Edamame is a crop that is extremely free from waterlogging. The excess water must be discharged in time after Rain Water stops. In fact, the yield of edamame has been affected to a certain extent after waterlogging, and the editor's method is only to prevent the yield of edamame from being reduced again and affect the economic interests of growers. I also hope that this article of the editor can help you.
