The latest remedial measures after peanut waterlogging

Peanut is one of the most important economic crops in China, which is widely planted. During the period of peanut planting, waterlogging caused peanut to suffer serious economic losses. So what is the cause of peanut waterlogging? How do I fix this? Let's take a look at it together with Xiaobian.

1. Peanut waterlogging hazard

Peanut growth can not be separated from water, seedling stage to soil relative humidity of 50%-60% is appropriate, and when the soil humidity is higher than 90% or accumulated water, the lack of oxygen in the soil, peanut root respiration and absorption will be inhibited, resulting in incomplete root development, ground parts grow thin, forming tall seedlings, flowering nodes high, effective fruit rate is low. The soil relative humidity is 60%-70% in the period of peanut anthesis. When the humidity is too high, it is not only unfavorable to the development of peanut pod, but also causes the shell color change, oil content reduction, even pod mildew and deterioration, losing economic value.

2. Causes of waterlogging

Peanut waterlogging harm is caused by low-lying, heavy soil viscosity, unable to discharge excess water, resulting in ponding roots; second, rainfall period is long or excessive rainfall season, surface water and groundwater are too deep, can not be discharged in a short time. Peanut likes drought and fears humidity, and waterlogging has a great impact on its growth and development. After peanut premature aging and waterlogging, measures should be taken in time to reduce disasters and ensure production.

3. Remedy measures

First of all, it is necessary to remove accumulated water in time. According to the ponding situation and terrain in the field, there are mechanical drainage and ditch drainage methods in this case. Try to drain the accumulated water in the field and minimize the ponding time in the field. When the soil moisture content is too high, it should be broken in time to disperse moisture, so that the soil permeability is good to reduce the phenomenon of rotten fruit. Peanut after flooding, a large number of soil nutrient loss, coupled with weak root absorption capacity, then timely topdressing fertilizer for peanut recovery growth and increase yield are extremely beneficial. After waterlogging, the conditions are high temperature, high humidity, weak peanut growth, low resistance, various diseases and insect pests will occur, so timely investigation and reproduction are needed to control the spread of the disease.
