First, mid- August weather forecast
Expected in mid-August, China's main rain area will be located in the eastern part of Northwest China, North China, Northeast China, Huang-Huai, late rainfall of 40 to 80 mm in some areas where the southern part of Northeast, the Huang-Huai northern, central and southern North China and other places There are 90 to 120 mm, and 140 to 180 mm in some areas. Most of the above-mentioned areas are 3 to 70 % more than normal , and the local area is 1 to 2 times more. In addition, there are multiple rainfalls in the coastal areas of South China and western and southern Yunnan, with rainfall ranging from 30 to 60 mm and local areas ranging from 80 to 120 mm.
　　 In mid-August, more rainy weather Zhouqu area, the cumulative rainfall is 40 to 80 mm, 90 to 150 mm (drawings) in some areas; 1 to 5 percent above normal times higher than normal in some areas above normal 2 More than double. The main rainfall periods will appear around the 11th to the 13th , 16th to 17th , and 19th .
　　 In mid-August, and more hot weather in the south, JAC, southern, northern and southern China, Sichuan, Chongqing and other places will have 5 to 8 in the light of day maximum temperature above 35 ℃.
　　 In mid-August, the Northwest Pacific and South China Sea will have 1 to 2 tropical cyclone.
Second, the possible impact of weather on agricultural production in mid- August
(1) There is more precipitation in the northeastern part of the country, and the soil in some areas is too wet, and the low temperature of rain and rain is not good for crop growth and development.
　　 In mid- August , due to the influence of rainfall, the southern part of the northeastern region will continue to be too wet. Some local farmland may have waterlogging, and the temperature is low. The low temperature and raininess are not good for soybean pods and corn grouting, and it is not conducive to spring wheat harvesting and season. Rice heading grouting.
(2) The drought in central and western China will be alleviated, but strong convective weather will easily cause crops to fall; the drought in some parts of Inner Mongolia will continue or develop.
　　 In mid- August , the precipitation in the eastern part of the northwestern region, North China, Huanghuai and other places will be more favorable, which will benefit the soil growth and alleviate the drought in central and western parts of North China. However, local thunderstorms and strong convective weather are likely to cause crops such as corn and cotton to fall. In the first ten days of Inner Mongolia, there is less precipitation, and the drought in the central and western regions will continue or develop, which is not good for crops and pasture growth.
(3) The high temperature weather in the southern region is unfavorable to the growth and development of cotton in southern rice and Yangtze River basins.
　　 In mid- August , the continuous high temperature weather in Jianghan, Jianghuai, Jiangnan, central and northern South China, and Sichuan Basin will affect the first-season rice flowering in the Yangtze River Basin, which will lead to an increase in empty shell rate and a decrease in seed setting rate. Unfavorable; it is very unfavorable for the growth and maturation of other local crops, vegetables, fruits, etc., which may lead to curling of leaves, falling flowers and fruit, etc., and reducing the yield and quality of vegetables, fruits and fruits.
(4) Tropical cyclones in coastal areas are not good for agricultural production
　　 In mid-August, the Northwest Pacific and South China Sea will have one or two tropical cyclone, which brought winds of storm easily and cause losses to the coastal areas of agricultural production.
Third, agricultural production advice
First, it is necessary to strengthen field management in all parts of the north to promote the formation of autumn harvest crops. Northeast China needs to pay close attention to the process of heavy precipitation, timely clearing ditch drainage, reducing the risk of waterlogging; the northwest region needs timely harvesting and drying spring wheat, and strive to return the grain to the warehouse; North China needs to seize the opportunity of precipitation, strengthen water storage and water conservation, rational irrigation, ensure crops It needs water for later growth and development; in areas where drought still exists, it is necessary to do drought and drought relief work.
Second, the first season rice fields and late rice fields in the Jianghuai, Jiangnan, northern South China, Sichuan, Chongqing and other places need to take active measures to reduce the impact of high temperature weather, so as to avoid high temperature heat damage. In addition, coastal areas in South China should pay attention to prevent tropical storms from causing losses to agricultural production.
Third, all localities need to strengthen the monitoring and control of pests and diseases of rice, cotton, corn and other crops.
