In the next 10 days, there will be a wide range of high temperature weather in the south.

At present, the first season rice in the Yangtze River Basin is in the heading to filling stage, and the cotton is in the flowering stage. The late rice in Jiangnan and South China is in the period of transplanting to green till tilling. From late July to early mid-August, most of the southern part of the country continued to have hot and hot weather. In central and southern Hunan, most of Jiangxi, central and western Zhejiang, north-central Fujian, and northwestern Guangxi, high temperature weather of more than 11 days ≥ 35 °C was common. The high temperature weather caused the late rice to be retarded in some areas, and the rice ear development and flowering pollination in a single season were also affected. Continued high temperature and low rainfall caused light to moderate drought in southern Hunan, north central Guangxi, southeastern Guizhou and eastern Yunnan. Linyi Fertilizer Network Copyright

It is expected that on August 13-15, high temperature weather with daily maximum temperature above 35 °C will occur in Sichuan Basin, Hubei, Jiangnan and South China. The highest daily temperature in parts of the eastern and southern Sichuan Basin can reach 37-39 °C; On the 22nd, Chongqing, Hubei, eastern Guizhou, Jianghuai, Jiangnan, and northern China continued to have temperatures above 35 °C. The highest temperatures in Chongqing, southern Hunan, southern Anhui, Zhejiang, and Fujian reached above 38 °C. Linyi Fertilizer Network Copyright

High temperature is easy to cause poor pollination, increase in empty shell rate, and increase in cotton buds, which affects the formation of yield. High temperature is very unfavorable for the growth and maturation of vegetables, melons, etc. It is easy to cause the leaves to curl, fall and fall, and even "burning", etc., to reduce yield and quality. At the same time, high temperature makes the fruits and vegetables difficult to preserve and the transportation loss increases. At the same time, the high temperature and low rainfall will lead to the continuous development of drought in southern Hunan, northwestern Guangxi, southeastern Guizhou and northeastern Yunnan.

1. At present, the positive production of rice in the southern region has formed a critical period. Pay attention to water temperature regulation and "daily irrigation" to avoid the occurrence of heat damage. The late rice area should maintain shallow water irrigation to alleviate the adverse effects of high temperature. Linyi Fertilizer Network Copyright

2. The cotton producing areas in the Yangtze River Basin should pay attention to topping and pruning, promote ventilation and light transmission, and timely water the cotton fields in the morning and evening to reduce the impact of high temperature and reduce falling flowers.

3. The dry areas in Hunan, Guangxi, Guizhou and other places should rationally allocate water resources, ensure water use in paddy fields, and strengthen water storage and water conservation to reduce the adverse effects of drought on crop growth and development. Linyi Fertilizer Network Copyright

4. All localities should strengthen the water management of vegetables, melons and fruits, and adopt measures such as tiling and scaffolding to reduce the temperature of the field, reduce the impact of high temperature, and ensure the supply of vegetables and fruits in summer.
