1. As high temperature with drought is the most harmful to crops, and it is impossible to control the occurrence of high temperature weather at present, start with drought resistance and timely irrigation, not only to achieve the purpose of temperature regulation with water, but also to ensure the water supply of crops and reduce the high temperature hazard. For example, early rice in the filling stage can be irrigated frequently with shallow water, irrigated daily and drained at night or sprayed (according to the test, the field temperature can rapidly drop by 2-5 degrees Celsius, the relative humidity can increase by 10% - 20%, and the effective time is about 2 hours. The higher the temperature, the better the effect of cooling and humidifying after spraying) to reduce the field temperature, increase the humidity, and prevent "high temperature forcing ripening", Increasing 1000 grain weight, strengthening field water management for late rice in seedling stage can also prevent seedlings from burning under high temperature and dying due to lack of water;
2. Fertilization outside the root and spraying phosphorus and potassium fertilizer can be used to enhance the high-temperature resistance of crops (rice, etc.);
3. Vegetables can be cultivated in protected areas such as shading nets (with the functions of blocking strong light, reducing high temperature, preventing evaporation, etc.) to achieve the goal of stable yield;
4. For orchards, irrigation can increase the water supply of fruit trees or cover the trees with straw to reduce the temperature and prevent water evaporation, which can also play a role in reducing the high temperature hazard;
5. Peasant friends should do a good job in cooling and heatstroke prevention, especially avoid working in the field before and after noon (sun exposure).
