What harm will waterlogging bring?
1. Soil hypoxia: rotten roots and dead seedlings caused by excessive accumulation of water and soil hypoxia.
2. Root system frustration: Root system respiration is inhibited, causing "physiological drought" and lodging.
3. Production of toxins: In an oxygen-deficient environment, aerobic microorganisms are extremely active and produce a bunch of harmful substances that poison the roots of crops.
4. Fertilizer loss: If there is too much water, the fertilizer melt will be washed out more or less, and it will flow out and infiltrate with the water.
5. Roots died in the sun: After the rain has passed and the weather is clear, the roots exposed by the rain washed away are easy to be sunken.
6. Pests and diseases: The affected crops are already very fragile, and the high temperature and humidity environment can easily induce pests and diseases.
How can we reduce the losses caused by waterlogging
1. Primary drainage: Drain as soon as possible, and directly use pumping or digging methods to reduce the soaking time; clear stubble and land preparation in fields that have been seriously damaged.
2. Arrange the crops: the root system is easy to fall down due to damage, it should be corrected manually after drainage, and the silt on the surface of the crop should be carefully washed with clean water. At the same time, rotten leaves and residual leaves should be trimmed and sorted. For crops that can still grow after the disaster, such as eggplants, peppers, etc., properly trim the dense foliage
Reduce plant burden and prevent wilting caused by physiological disorders; for melon vegetables, remove old yellow leaves at the root base.
3. Cultivation and soil cultivation: timely cultivation and cultivation of soil to improve soil compaction, poor ventilation and other soil problems, and timely cultivation of soil to prevent lodging.
4. Appropriate topdressing: fertilizer loss is too much. After cultivating the soil, it is necessary to supplement nitrogen, phosphorus and potassium quick-acting compound fertilizer, and topdressing potassium dihydrogen phosphate on the foliar surface to promote the development of new roots and new leaves. It is also recommended to use foliar fertilizer for supplementary elements, which has a quicker effect and helps the plant to restore health.
5. Prevention and control of pests and diseases: After the flooding, the weather changes to fine weather. At this time, the humidity in the field is high and the weather temperature is also high, which is the best time for high incidence of pests and diseases. Coupled with plant weakness, it is easy to cause serious damage or even abortion. The major farmers should be based on their own crops and the occurrence of diseases and insect pests.
Law is timely to do prevention. Prevention should be the main focus of prevention, and highly toxic pesticides should not be used to avoid phytotoxicity.
