Henan will welcome large-scale precipitation! What is the impact of heavy rain+heavy rain+thunderstorm and strong wind on crops?
The impact on crops is enormous. After extreme weather such as rainstorm, it is likely that the damaged particles of crops will not be harvested, and the soil will be destroyed, so that crops cannot be planted again.
How destructive is extreme weather such as rainstorm to crops?
The rainfall of rainstorm is sharp and destructive. When the industrial and agricultural drainage pipes are not smooth, it is easy to cause water accumulation. The porosity of the soil layer is filled with water, which leads to the lack of oxygen in the roots of terrestrial plants, which will lead to the limitation of crop production. Without 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 be harmful to the flowering period of crops, leading to powder blockage, thus reducing the fertility rate of fruits and falling flowers and fruits. Many pathogens germinate in high humidity natural environment, such as diseases and pests such as high temperature and low temperature gray mold, which will affect crops. A large amount of water will also lead to the production of many wilt pathogens and damage crops, such as green wilt, angular leaf spot and other pests and diseases. After the rainstorm, the buds of new trees germinate rapidly, which will cause many pests to breed.
what impact will the rainstorm and extreme weather have on the environment?
Waterlogging disaster will occur after rainstorm. 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 soil water content is often in a full state because of the high groundwater level. 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. However, waterlogging and sewage disasters coexist in most areas, and sometimes they cannot exist completely alone, so they are usually called waterlogging disasters.
Waterlogging disaster is caused by rainstorm, and the drainage pipeline is not smooth, which is easy to cause waterlogging. The porosity of the soil layer is filled with 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 the production of crops. Rainstorm is one of the major climate disasters in China, and its harm mainly includes flood disaster and flood disaster. When the rainstorm temperature occurs, more lightning strikes and winds often lead to mountain floods, river floods, floods, crops, engineering buildings, material supply, human and animal casualties, crop production or production, 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 workers and peasants' production, transportation, communication, facilities, urban operation, people's daily life, ecological environment protection and so on.
