August 29th to August 22nd

Anhui

A continuous high temperature weather occurred in the province. Continuous hot weather, high temperature and short rain led to the rapid decline of soil moisture in Anhui and the rapid development of drought.

On August 14~16, there was an obvious precipitation process in our province, which played a good role in alleviating high temperature and drought.

But due to uneven precipitation, the large and part of Huaibei

Drought severity

It has not been completely relieved.

In mid August, the precipitation in the Huaihe River, the central part of Yangtze Huaihe River, the western part of the Yangtze River and the southern part of the Yangtze River were more than 1 to 2 times larger than that in the southern part of the Yangtze River. Most other areas were less than 2 to 1 times.

At present, Anhui is at the critical stage of growth and development of autumn harvest crops, cotton is in flower and boll stage; summer soybean is generally blooming and pod setting; sweet potato is in the forming stage of potato tuber; summer maize is generally tassel; the summer maize is in the stage of booting stage; the first heading of Jianghuai rice and some early maturing varieties are grouting one by one.

23 days later, the temperature of the whole province eased, and the mid - term rainfall was obvious.

At present, the temperature conditions of 25~32 C are suitable for crop growth and grain filling.

Future weather trends and Countermeasures

According to the latest forecast of Anhui Meteorological Observatory, Anhui province has many

Thunder shower

The weather may be accompanied by severe convection such as short-time heavy rainfall, thunderstorm and strong winds.

At present, the autumn harvest crops in Anhui will enter the critical period of growth in the middle and late stages. Thunderstorm weather is expected to further alleviate or relieve the drought in the early stage.

However, we should pay close attention to the possible effects of strong winds and other severe convective weather on the crops in place, and take early measures to mitigate the losses.

Accordingly, it is suggested that:

1. We should strengthen the management of late rice field management. We should insist on intermittent irrigation during the grain filling stage to keep the field dry and wet.

2, to cotton in the flowering and boll stage, we should prune and branch frequently, so that the farmland can maintain good ventilation and light pmission conditions, and reduce the abscission of cotton bolls and bolls.

3. After the severe convective weather such as short-time heavy rainfall, thunderstorm and strong wind, the farmland should be draining and waterlogging timely. Besides, the lodging crops should be timely seeding, washing seedlings, cultivating soil and fixing roots, supplementing quick acting fertilizers, and promoting crop recovery.

4. the weather conditions of high temperature and high humidity are also conducive to the occurrence and spread of pests and diseases such as rice planthopper and so on.
