Strong precipitation in northern Hunan, early rice should be harvested in advance

According to the Central Meteorological Observatory, in the next three days, China's heavy rainfall areas will be under pressure, and the main rainfall belt will be located in the middle and lower reaches of Chongqing and Guizhou to the Yangtze River. Especially in the south of the Yangtze River where rainfall has been quiet for many days, the rain will gradually strengthen. The long-lost rainfall will gradually ease the “high fever” in Jiangnan and other places. However, today and tomorrow, the high temperature weather is particularly high, and the Central Meteorological Observatory continues to issue high-temperature warnings. It is expected that there will be heavy rains in the south of Sichuan, Chongqing, central and northern Guizhou, northwestern Hunan, southern Hubei, southern Henan, and central and southern Susong, day to night, including northern Guizhou, southeastern Chongqing, and southwestern Hubei.

Agricultural advice

1. It is suggested that the plots with early rice maturity of more than 85% in Hunan and Jiangxi will be harvested in time before the arrival of heavy precipitation. The early rice has been harvested to pay attention to rain storage; the harvest completion area should speed up the preparation of land and paddy fields to ensure timely shift of late rice. plant.

2. In some parts of southern Jiangnan, there is still a high temperature with a daily maximum temperature of ≥35°C, which is unfavorable for early rice filling. It is recommended to use flow irrigation, daily irrigation or sprinkler irrigation to reduce the adverse effects of high temperature; most of southern China has more sunny and less rainy weather, Early rice filling and mature harvesting are beneficial overall.
