With the intensification of global climate change, extreme weather events such as high temperature, drought, heavy rain and hail have occurred frequently, posing a severe challenge to agricultural production. Under these extreme climatic conditions, how to effectively protect crops and ensure their normal growth and development has become an urgent problem to be solved in the agricultural field. As an efficient shading tool, the black sunshade net has shown significant protective effects in this regard.The main function of the black sunshade net is to block sunlight and reduce direct sunlight, thereby reducing the surface temperature and the temperature of crop leaves. In hot weather, the shade net can significantly reduce the temperature of the environment in which the crops are located, reduce the transpiration of the leaves, maintain water balance, and improve water use efficiency. This not only helps crops resist high temperature heat damage, but also reduces physiological drought caused by excessive water evaporation.In the dry season, the black sunshade net also plays an important role. By reducing the absorption of solar radiation heat, the shade net can reduce the air temperature and soil temperature in the covered area, slow down the evaporation rate of soil moisture, which is conducive to maintaining soil moisture and improving the drought resistance of crops. In addition, the sunshade net can also reduce the mechanical damage of strong winds to crops, protect the soil structure, and reduce the loss of soil and fertilizer.In the face of extreme weather such as heavy rain and hail, black sunshade net also performs well. It can reduce the direct scouring of crops by heavy rain, reduce the mechanical damage of hail to leaves and fruits, and reduce the degree of crop damage. At the same time, the sunshade net can also provide a certain insulation effect to prevent crops from suffering from frost damage in cold weather.In addition to the protective effect against extreme climates, black sunshade net can also reduce ultraviolet radiation and reduce the incidence of pests and diseases. The microenvironment covered by the sunshade net is conducive to the healthy growth of crops, reduces the breeding of pests and the spread of viruses, thereby reducing the use of pesticides and is conducive to the sustainable development of agriculture.In summary, black sunshade net has a significant protective effect on crop growth under extreme climatic conditions. It can not only reduce temperature and maintain humidity, reduce heat damage and drought pressure on crops, but also prevent mechanical damage from heavy rain and hail, provide insulation effect, and reduce the occurrence of pests and diseases. Therefore, the widespread application of black sunshade net in agricultural production is of great significance for improving crop resistance, ensuring food security and promoting sustainable agricultural development.
