First, timely support the vegetable plant. It is necessary to correct the lodging of the vegetables, reduce the phenomenon of mutual extrusion, and properly cultivate the roots. The second is to spray foliar fertilizer in time. After the rainstorm, the roots of the vegetables are poorly capable of absorbing water and fertilizer. At this time, the foliar fertilizer should be sprayed in time. Generally, 0.2% potassium dihydrogen phosphate + 0.5% urea solution can be used to make the vegetables quickly recover. The third is to scatter the wood ash in time. Spreading grass ash can absorb water, reduce soil moisture, increase nutrients, improve the environment, and prevent diseases. The convenience of rural sources should be applied in time. The fourth is to cultivate the loose soil in time. After the rain, the soil is compacted. When the soil is slightly dry, the soil is ploughed to improve the soil structure and improve the root activity. The fifth is to promote rain-proof cultivation. Covering the top of the greenhouse with plastic film, shading net and other materials can not only avoid the direct germination of rainwater, but also effectively improve the temperature, light, humidity, gas and other microclimates in the shed, and reduce the number of chemical control and the amount of drug used.
