How to remedy edamame after a flood

The arrival of summer is accompanied by the rainy season, and many places in the south have already experienced continuous heavy rain. Summer is also the planting season for edamame, and edamame is the crop least tolerant of waterlogging; when affected by waterlogging, it causes root rot and slows down growth. So what should be done after edamame is flooded? How can edamame avoid a reduction in yield? Let's take a look below!

1. Drain water in time

When a flood occurs due to heavy rain, the water should be drained from the planting field immediately after the heavy rain stops, to avoid edamame suffering further waterlogging damage. Dig out the soil in the field beds, make sure the field beds, surrounding ditches and waist ditches, the three ditches, have no excess mud blocking the discharge of standing water, improve the drainage efficiency between the fields, drain the excess standing water in the field as soon as possible, and after draining the standing water, reduce the water content in the soil.

2. Topdress in time

After the edamame field suffers waterlogging disaster, waterlogging very easily carries away the fertilizer and nutrients in the soil, causing a sharp decline in soil quality. Therefore, after the flood stops, quick-acting fertilizer should be sprayed on the plants immediately to restore the growth rate of edamame as soon as possible and promote the transformation of the seedling condition. After draining the excess standing water in the field, apply urea per mu; if there is a case of stiff seedlings, some foliar fertilizer or regulators can be sprayed, such as potassium dihydrogen phosphate, etc., which can promote the recovery of stiff seedlings and get them to start normal growth.

3. Cultivation and weeding

After the waterlogging recedes, the edamame field should be cultivated, because cultivation can quickly reduce the water in the soil and enhance the ventilation and air permeability of the soil. Promote the root growth of edamame and remove excess weeds in the field, so as to prevent weeds from competing with the plants for nutrients. Generally, after waterlogging, cultivation should be carried out at least three times, and according to the growth condition of edamame, avoid lodging in the future.

4. Prevent and control diseases

After heavy rain, if high-temperature and high-humidity weather occurs, it will make edamame extremely prone to many pathogens and extremely prone to diseases and insect pests, such as rust disease and aphids, etc. Therefore, in order to prevent or control these diseases, more pesticides should be sprayed for prevention and control; triadimefon can be used to control rust disease, imidacloprid to control aphids, and deltamethrin to control pod borers, etc. Use different agents according to different diseases, and never use excessive amounts, which is harmful to the plants and has no benefit at all.

5. Chemical control to prevent excessive growth

Continuous heavy rain will cause insufficient sunlight for edamame, leading to excessive vegetative growth of the plants, with only flowering and no fruiting, and the fruits at the top cannot receive nutrients. Therefore, during the flowering and fruiting stage of edamame, some chemical control agents can be sprayed to control the excessive growth of the plants. Excessive growth of edamame not only cannot increase yield, but only consumes more fertilizer and water.

The above are the specific handling methods after edamame suffers a flood. Edamame is a crop extremely intolerant of waterlogging, and after the rain stops, the excess standing water must be drained in time. In fact, after suffering waterlogging, the yield of edamame has already been affected to a certain extent. The editor's method is only to prevent edamame from reducing yield again and affecting the economic interests of growers. I also hope this article by the editor can help everyone.
