Henan will usher in a large-scale precipitation! What is the effect of rainstorm+heavy rainstorm+thunderstorm and gale on crops?

The impact on crops is enormous. After extreme weather such as heavy rain, it is likely to harvest damaged crops and destroy the soil, resulting in crops being unable to be planted again.

How destructive is extreme weather such as rainstorm to crops?

Heavy rain is sharp and destructive, and it is easy to cause water accumulation when industrial and agricultural drainage pipes are not smooth. The pores of the soil layer are full of water, which leads to the lack of oxygen in the roots of terrestrial plants and the limitation of crop yield. When there is no sunshine in rainstorm days, the high efficiency of photosynthesis of green plants will be affected, and the respiration of plants will be weakened, which will hinder the upward transportation of crop carbonate and lead to the lack of basic raw materials for photosynthesis in leaves. Rainstorm temperature will also cause harm to the flowering period of crops, leading to powder blockage, thus reducing the fertilization rate of fruits and falling flowers and fruits. Many germs germinate in high humidity natural environment, such as diseases and pests such as high temperature and low temperature gray mold, which will have an impact on crops. A large amount of water will also lead to the production of many Fusarium wilt pathogens and damage crops, such as bacterial wilt, angular leaf spot and other pests and diseases. After the rainstorm, the buds of new trees germinate rapidly, which will lead to the breeding of many pests.

What impact will it have on the environment after heavy rain and extreme weather?

Waterlogging will happen after heavy rain. Waterlogging refers to storing water in the field after rain, which exceeds the flood control capacity of crops. The key to the stain is that the groundwater level is high and the soil water content is often in a full state. There is too much water in the theme active layer of crop root system, which is not conducive to crop growth and development and causes pollution disasters. Waterlogging and sewage disasters coexist in most areas, and sometimes they can't exist completely alone, so they are usually called waterlogging disasters.

Waterlogging disaster is caused by heavy rain, and the drainage pipeline is not smooth, which is easy to cause waterlogging. The pores in the soil layer are full of water, which leads to the lack of oxygen in the roots of terrestrial plants, inhibits the physiological activities of the roots, improves the whole process of suspected gas, and produces toxic substances, thus limiting crop yield. Rainstorm is one of the main climate disasters in China, and its harm mainly includes flood disaster and flood disaster. When the rainstorm temperature occurs, more lightning strikes and strong winds often lead to flash floods, river floods, floods, crops, engineering buildings, material supply, human and animal casualties, crop production reduction or extinction, and traffic and communication obstacles. Heavy rain can cause disasters immediately, but it is also easy to cause geological and environmental disasters such as collapse, landslide and landslide. Rainstorm and flood disasters involve industrial and agricultural production, transportation, communication, facilities, urban operation, people's daily life, ecological environment protection and so on.
