The Latest Remedial Measures After Peanuts Suffer Waterlogging Damage
Peanut is one of the important economic crops in our country, with an extremely wide planting range, and during the peanut planting period, the occurrence of waterlogging damage causes peanuts to suffer severe economic losses. So what are the causes of peanut waterlogging damage? How should it be remedied? Follow the editor to take a look.
1. Harm of peanut waterlogging damage
Peanuts cannot grow without water. During the seedling stage, the relative soil humidity should preferably be 50%-60%, and when the soil humidity is higher than 90% or there is standing water, the soil lacks oxygen, and both respiration and absorption by the peanut root system are inhibited, causing incomplete root development, thin and weak growth of the aboveground parts, the formation of leggy seedlings, high flowering node positions, and a low effective pod-setting rate. During the peanut flowering and pegging stage, the relative soil humidity should preferably be 60%-70%. When the humidity is too high, it is not only unfavorable to peanut pod development, but also causes the pod shells to discolor, reduces the oil content, and may even cause the pods to become moldy and deteriorate, losing their economic value.
2. Causes of waterlogging damage
The first cause of waterlogging damage in peanuts is low-lying terrain and heavy clay soil, which cannot drain excess water away, causing standing water and root rot; the second is a long rainy period or a season with excessive rainfall, when surface water and groundwater are too deep and cannot be drained away in a short time. Peanuts like drought and fear moisture, and rain and waterlogging have a relatively large impact on their growth and development. After early senescence and waterlogging damage in peanuts, measures should be taken promptly to reduce damage and preserve yield.
3. Remedial measures
⟦NL>First of all, standing water should be drained promptly. According to the standing water conditions in the field and the terrain, methods such as mechanical drainage and trench digging for drainage can be used to find ways to drain the standing water from the field and minimize the time standing water remains in the field. When the soil water content is too high, the film should be broken promptly to disperse soil moisture, so that the soil permeability is good, thereby reducing the occurrence of rotten pods. After peanuts are flooded, soil nutrients are lost in large amounts, and in addition the absorption capacity of the root system is weakened. At this time, timely topdressing fertilizer is extremely beneficial for peanut growth recovery and increasing yield. After waterlogging damage, with high temperature and high humidity conditions, plus weak peanut growth and low stress resistance, various diseases and insect pests will occur, so timely investigation and control are needed to prevent the spread of the disease.
