What to Do After Edamame Is Hit by Flooding? Latest Treatment Methods Explained in Detail
The arrival of summer also brings the rainy season along with it, and many places in the south have already had continuous heavy rain. Moreover, 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 hit by flooding? How can edamame yields be kept from dropping? Let's take a look below!
1. Drain water in time
When flooding occurs due to heavy rain, the water should be drained from the planting area immediately after the rain stops, to prevent edamame from suffering further waterlogging damage. Dig out the soil in the field beds, make sure the field beds, surrounding ditches and waist ditches are free of excess mud blocking the drainage of accumulated water, improve the drainage efficiency between the fields, drain the excess accumulated water from the field as soon as possible, and reduce the water content in the soil after draining the accumulated water.
2. Apply topdressing in time
After the edamame field suffers waterlogging damage, waterlogging very easily carries away the fertilizer and nutrients in the soil, causing a sharp decline in soil quality. Therefore, after the flooding 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 recovery of the seedlings. After draining the excess accumulated water from the field, apply urea per mu; in cases of stunted seedlings, some foliar fertilizer or regulators such as monopotassium phosphate can be sprayed, which can promote the recovery of stunted seedlings so they begin normal growth.
3. Cultivate and weed
After the waterlogging recedes, the edamame field should be cultivated, because cultivation can quickly reduce the water in the soil and enhance the soil's ventilation and permeability. It promotes the root growth of edamame and removes excess weeds in the field, so that weeds do not compete with the plants for nutrients. Generally, after waterlogging, cultivation should be carried out at least three times, and according to the growth of the edamame, lodging should be prevented in the future.
4. Prevent and control diseases
After heavy rain, if hot and humid weather occurs, it will make edamame extremely prone to many pathogens and extremely prone to pests and diseases, such as rust and aphids. 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, imidacloprid to control aphids, and deltamethrin to control pod borers. Use different agents according to different diseases, and never use them in excess, as that brings nothing but harm to the plants.
5. Chemical control to prevent excessive growth
Continuous heavy rain will cause insufficient light for edamame, leading to spindly growth of the plants, with only flowers and no pods, and the fruits at the top cannot receive nutrients. Therefore, during the flowering and podding stage of edamame, some chemical control agents can be sprayed to control the spindly growth of the plants. Spindly growth of edamame not only fails to increase yield, but only consumes more fertilizer and water.
The above are the specific treatment methods after edamame suffers flooding. Edamame is a crop extremely intolerant of waterlogging, so after the rain stops, the excess accumulated water must be drained in time. In fact, after suffering waterlogging, the yield of edamame has already been affected to a certain extent; the methods here are only meant to keep edamame from losing yield again and affecting the economic interests of growers.
