At present, the cotton in the Yangtze River valley is in the stage of flowering and bud, the spring maize is in the period of tasseling to milky maturity, the rice in one season is in the tillering to the booting stage, the early rice is in the stage of heading and filling to milk, and the late rice is in the stage of breeding. July 8 08 am to 08 pm on the 14th, the Yangtze River during heavy rainfall occurs, most of Jiangsu, Anhui, south-central, southeastern Hubei, northern Hunan and Jiangxi, Zhejiang and most, most of Guizhou, Chongqing most, southern Sichuan Precipitation in the southwestern part of Yunnan is more than 50 mm. The precipitation in southern Jiangsu, southern Anhui, southeastern Hubei, northeastern Jiangxi, northwestern Hunan, etc. reaches 100-300 mm, and precipitation in some areas exceeds 500 mm.

The heavy rainfall caused some paddy fields in southern Jiangsu, southern Anhui, southeastern Hubei, northeastern Jiangxi, and northwestern Hunan to be destroyed. Some of the rice and early rice were lodging, and the land was even damaged. In late autumn, some rice seedlings were delayed. In addition, the rainy and illuminating effect on the early rice filling rate, leading to the decline of 1000-grain weight in early rice, also affects the rice tiller in the first season.
Heavy rainfall caused some farmland to accumulate water, cotton, corn and other dryland crops fell, low-lying cotton fields were dead and dead, cotton buds fell off a lot, and corn quality was also affected. Heavy rainfall also caused poor drainage and low-lying farmland vegetables, fruits and other economic crops were flooded and soaked, rotten roots and dead leaves were not harvested.
At the same time, the rainy weather and the farmland waterlogging caused by continuous precipitation are easy to induce the occurrence and spread of rice blast, sheath blight, bacterial blight and cotton blight.
In addition, heavy precipitation also caused serious losses in fishery production, causing some fish ponds to overflow and fish, and infrastructure damage.
According to the Ministry of Agriculture scheduling situation, as of July 12, Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Chongqing, Sichuan, Guizhou eight provinces (city) due to heavy rains led to crops affected 1127.33 thousand hectares, of which disaster 384.67 thousand hectares, The harvest was 86.67 thousand hectares. According to the Hubei Provincial Department of Agriculture at 10:13 on July statistics, the province's crops affected area of 1018.82 thousand hectares, disaster 407.54 thousand hectares, one thousand hectares of crops 81.86; 76.67 fishery affected area of one thousand hectares; agricultural disaster direct economic losses of 4.723 billion yuan.
According to the China Meteorological Administration disaster reporting system, as of July 13, Anhui Province, crops affected area of 277.14 million hectares, of which crops area 29.07 million hectares, agricultural losses 989 million yuan; Jiangsu Nantong crops affected area of 23.60 million hectares, disaster area 11.96 thousand hectares; the area affected by crops in Zhaotong, Yunnan is 1.03 thousand hectares, and the agricultural loss is 0.08 billion yuan. As of July 14, Yancheng City, Jiangsu Province, crops affected 5.75 million hectares of crops 0.57 thousand hectares, in addition Qin Dong-jin had 80 fish ponds flooded loss of about 005 million yuan, agricultural disaster economic losses of about 027 million yuan; Hunan Yueyang The area affected by crops in the city is 14.30 thousand hectares, including 11.00 thousand hectares of disaster area , 3.50 thousand hectares of unrestricted area , and 113 million yuan of agricultural losses ; 4.30 thousand hectares of crops affected by Yiyang City, Hunan Province ; and 10.00 thousand hectares of corn in Bijie City, Guizhou Province , artichoke 0.27 thousand hectares and so on.
Future Agricultural Production Proposal
It is expected that in the next ten days, the rainfall area will be wide and the rain belt will be unstable. After the 14th , the rainfall area will be lifted to the Huaihe River Basin. On the 15th and 19th , there will be a significant rainfall process in the Huaihe River Basin, and some areas have heavy rain. Heavy rains, heavy rainfall will mainly occur on the 16-17th . On the 15th to 21st , the southwestern region will be dominated by rainy weather. The rainfall is generally 40-90 mm. In the northeastern part of Sichuan and Chongqing, the rainfall is 100-180 mm and the local area is about 200-300 mm. Heavy rainfall will occur. 15-18 days. At present, the Yangtze River Basin and the Huaihe River Basin are in the critical period of crop growth and yield formation. Suggestions:
　　 1. The Yangtze River Basin should seize the stage of weakening of precipitation, and pay close attention to the drainage and drainage. After the end of the precipitation process, it is necessary to timely cultivate the soil and fertilize, and reduce the adverse effects of water and fertilizer loss in the farmland. Replanting and replanting some unrecognized farmland in time to make up for the damage caused by the disaster. The cotton area should be pruned in time to improve the ventilation conditions of the cotton field and reduce the buds falling off.
　　 2. The Huaihe River Basin should pay attention to clearing the ditch and preventing the occurrence of waterlogging on the farmland.
　　 3. All localities should strengthen the monitoring and prevention of pests and diseases.
