Is it good to rain after planting or transplanting vegetables? Why?

After sowing or transplanting vegetables, it is necessary to water them continuously to keep soil moisture, which is beneficial to seedling emergence and rooting. Isn't it good to rain after planting vegetables or transplanting rice seedlings?

When planting vegetables in spring, it is easy to lower the ground temperature with a little rain in Mao Mao, accompanied by northwest wind, which will delay the germination of vegetables or slow the emergence of seedlings, which will easily lead to seed rot.

After vegetables are sown in the open field, if it rains, it will help to keep soil moisture, but it will also lead to soil hardening, which is not conducive to seed emergence. It is necessary to cover the ground with a layer of decomposed farm manure, straw curtain or wheat bran in advance, or cover the ground with plastic film and canopy to prevent raindrops from hitting the ground.

Planting vegetables in autumn is most afraid of water accumulation, which affects seed respiration and needs to be prepared for drainage. In Chu Qing, the temperature rises suddenly during the rainstorm, and the seedlings will burn during the seedling stage, so it is necessary to pay attention to shading.

To raise seedlings in protected areas in winter, it is necessary to add plastic film, clean up snow and sundries, and ensure the temperature. If necessary, heating facilities should be added in the shed.

Most vegetables are transplanted by seedlings, which is to prevent all kinds of natural disasters and facilitate small-scale control of temperature, humidity and light. However, some vegetables have high density, so it is necessary to strengthen management when raising seedlings. Only ensuring enough seedlings is the first step in vegetable production, otherwise everything is empty talk.

After transplanting vegetables, as long as it is not heavy rain or continuous rain, rain is much better than insolation, which is relatively easy to manage. After transplanting vegetables, new roots will soon grow. As long as the roots are well rooted, the water absorption capacity and nutrient absorption capacity will increase, and the stress resistance will also increase.

The most difficult thing to manage in vegetable transplanting is the time before rooting. If it rains heavily, cover it with a canopy in advance to prevent raindrops from directly hitting the seedlings and causing damage to the stems and leaves, and also to prevent soil hardening. Continuous rainy days only need drainage, as long as there is no water, seedlings can be guaranteed to take root and sprout.

Seedlings are usually kept in the shade or shed, which is tender and weak. Before taking root, it will be sunny after the rain, so we should do a good job of shading and cooling, spray clear water or foliar fertilizer when necessary, and maintain a high air humidity. After gradually removing the sunshade net, the seedlings will adapt to the external environment.
