At present, most of the early rice in Jiangnan and South China are in the heading to milky stage, and some early rice in the south of South China has matured; the late rice in the south of the Yangtze River and South China is in the sowing and breeding period. From July 1st to July 12th, most of the rivers in southern and southern China have a maximum temperature of ≥35°C for more than 5 days. The high temperature days in western Jiangxi, southeastern Hunan, eastern Guangxi, western Guangdong and northeastern China are 8 In 12 days, part of early rice heading flowering and grouting were affected to some extent. Early rice in central and eastern Hunan, parts of Jiangxi, Guangdong and parts of Guangxi showed "high temperature ripening" phenomenon.

In the south of South China, there are many high-temperature and low-rain weather, and it is necessary to prevent early rice from “high temperature ripeningâ€.
The meteorological department expects that in the next 10 days, the high temperature and low rainfall in the south of the south of the Yangtze River and the northern part of South China will generally be between 35 and 38 °C. Continued high temperature will affect early rice flowering pollination and full grouting, resulting in increased empty mites; late rice seedlings are also vulnerable to high temperature hazards.
It is suggested that Jiangnan and South China should strengthen the field management of early rice early stage, actively defend against high temperature hazards, do not prematurely break water, adopt temperature regulation measures of sprinkler irrigation and daily irrigation night to prevent premature aging of plants; when rice grain maturity reaches 85-90% Timely harvesting, threshing and drying to avoid losses caused by adverse weather. After harvesting early rice, we must pay close attention to the progress of the whole field to ensure timely transplanting of late rice.
In addition, it is expected that Tropical Storm No. 2 "Conson" will affect the coastal areas of South China around the 17th. It is necessary to take precautions against the wind and rain caused by tropical storms and cause losses to agricultural production.
