Early rice in the filling stage of Jiangxi should be strengthened and managed to be alert to high temperature
Affected by the subtropical high pressure, the recent hot and cold weather in Jiangxi Province, the highest temperature since July 18 is generally above 35 °C; according to the early rice high temperature ripening index calculation, on the 21st there are Pingxiang, Zhangzhou, Xinfeng, Gaoan, Nanchang 9 counties and cities such as Yushu, Shangrao County, Guangfeng and Xingan have reached the standard of mild high temperature ripening.
The meteorological department expects the province to be sunny and cloudy from 23 to 24, with some showers or thunderstorms in the afternoon to night; in the southern part of the country, there are showers or thunderstorms on the 25th to 26th, the north is sunny and cloudy, some afternoon showers or thunderstorms; on the 27th, the province is sunny.

According to the information of the Agricultural Meteorological Observatory, the growth period of early rice in Jiangxi Province is delayed by 1 to 13 days compared with normal year. Most of the current stage is still in the stage of high temperature and sensitive period. The continuous high temperature and low humidity will cause the seed setting rate and 1000-grain weight to drop. Affect the output. Therefore, it is recommended that the early paddy field in the filling stage should still be strengthened. Flow irrigation, daily irrigation, irrigation, etc. can be adopted to cool and humidify, improve the field microclimate and reduce the adverse effects caused by high temperature.
