Since late July, there has been a high temperature and little rain weather in the South with the longest duration, the widest range of influence and the largest average intensity since 1961. The drought has developed rapidly and superimposed high temperature and heat damage, posing a serious threat to autumn grain production. The situation of agricultural drought resistance and disaster reduction is extremely severe. We should deeply understand the important significance of fighting high temperature and heat damage and drought to the overall situation of economic and social development, resolutely shoulder the political responsibility of ensuring national food security, do a good job in disaster prevention and mitigation, and go all out to win the war of fighting high temperature and heat damage and drought to win the autumn grain harvest. The notice stresses that agricultural and rural, water conservancy, emergency, meteorological and other departments at all levels should strengthen emergency duty, strengthen communication and consultation, fine and accurate dispatch of disasters, and study and judge the impact. We will continue to carry out prediction and forecast of disastrous weather, especially high temperature and drought, timely release early warning information, intensify disaster scheduling, refine the growth of crops affected by disasters to counties and plots, scientifically assess the impact of high temperature, heat and drought by regions, types and crops, sort out and put forward targeted disaster prevention and mitigation measures one by one, and provide scientific basis for accurate guidance. The circular stresses that every effort should be made to open up water sources for drought resistance. The water conservancy departments should strengthen the scientific regulation and management of water sources such as rivers, lakes and reservoirs, strive to ensure the demand for agricultural irrigation water, dynamically adjust the water project scheduling scheme, accurately connect each irrigation area, carefully calculate and use each water, and ensure the water use in the critical period of crop growth; Prepare and improve the drought relief plan, and take measures such as emergency water transfer, new water source, temporary pump erection and staggered peak rotation irrigation according to local conditions to ensure the emergency water for drought relief. The emergency response department shall timely start and adjust the emergency response, preset the emergency response force and flood control and drought relief materials and equipment, organize and carry out water supply and living assistance for the affected people, and ensure the safety of drinking water for the people. The meteorological department shall timely dispatch and transport operational aircraft to the drought stricken areas, prepare sufficient rain rockets and other materials, and guide all localities to carry out artificial rain enhancement operations in a timely manner. The "Circular" stresses that measures to resist high temperature and heat damage and drought should be implemented in different regions and conditions, and measures to stabilize production and increase production should be taken in different stages of crops. In areas with irrigation conditions, according to the development situation of drought, the key measures of water temperature regulation, such as deep-water cooling, small water frequent irrigation, and flowing water cooling, should be implemented; In the hilly land, "wangtiantian", the end of the irrigation area and other areas lacking water resources, water should be pumped by machinery and mechanical wells, and the favorable opportunity should be seized to carry out artificial precipitation enhancement, and the socialized professional service team should be organized to carry out spraying of foliar fertilizer, drought resistance and water retaining agent and other operations; For the plots that are seriously affected or even have no harvest, the late autumn crops such as sweet potato and miscellaneous grains should be replanted in a timely manner, and the middle rice in suitable areas can be harvested and stored as regenerated rice. For medium-sized rice with reduced seed setting rate caused by high temperature and heat damage, it is necessary to seize the limited filling time, scientifically apply ear grain fertilizer, spray foliar fertilizer, enhance photosynthesis and grain filling rate, and strive to increase grain weight to make up for the loss of seed setting rate; Double cropping late rice
