If the terrain is low-lying, a pump can be used for drainage if possible. Speed up and lower the water level in time. For flooded vegetable fields, the ground should be vacated to prevent vegetables from being flooded for too long and reduce losses. Timely drainage can restore the root capacity of vegetables as soon as possible, avoid waterlogging and reduce the death of vegetables caused by stagnant water.

2. Vegetable management

Straighten the vegetables lying down due to stagnant water in time to avoid squeezing each other, then cultivate the soil properly and spray the right amount of foliar fertilizer. If the soil is hardened, then it is necessary to loosen the soil in time, improve the structure of the soil, and restore the growth of the roots. Moreover, it is necessary to carry out artificial watering in time, clean the soil on the leaves, and pay attention to ensuring that the water quality is clean.
