The future of Anhui will help ease the drought, and the rain and topdressing should be done well.

Since March, Anhui Province has experienced high temperature and low rainfall along Huaihe River in the north. Since mid-April, drought has recurred in most areas and has continued to develop. By the end of April, most areas in the north of the Yangtze River had varying degrees of drought, and the area of ​​moderate to heavy drought increased. Due to weak precipitation and effective irrigation in early May, the current drought has eased slightly.

After the winter wheat returned to green, the combination of light, temperature and water meteorological conditions was better, which promoted the transformation and upgrading of winter wheat seedlings, and the overall growth was better than normal. After mid-March, the drought has developed again, and the water supply in the farmland is insufficient, which is not conducive to the growth of winter wheat in the vigorous growth stage. According to the survey of seedlings in early May, the height of wheat seedlings in most areas along Huaihe River is lower than normal. In some areas, the leaves of wheat are curled and the number of green leaves is less than normal. However, the total number of ears per mu is slightly better than that of the same period of last year. If the late drought continues to develop, wheat is insufficiently grouted and production may be affected.

Insufficient water also caused difficulties in transplanting early rice in parts of the south of the Yangtze River, and local high-grid land could not be transplanted; the seedlings of spring, sowing and drought crops such as cotton and corn were weak.

According to the forecast of the Anhui Meteorological Observatory, by the 11th, the province had a relatively obvious rainfall weather process from north to south, and may be accompanied by strong convective weather such as thunderstorms and strong winds. Among them, the rainfall process in the main wheat producing areas is today, the process rainfall is generally 10 to 30 mm, and the local is more than 50 mm, while the average temperature in the province is reduced by 6 to 8 °C.

At present, winter wheat along the Huaihei River has begun to grout, and the drought in most parts of Anhui Province is expected to be alleviated or relieved after this precipitation, which is conducive to increasing grain weight and reducing empty grain in the late winter wheat. According to this suggestion:

1. There will be obvious precipitation along the Huaihei River in the next few days, which can effectively alleviate the current drought. Therefore, the dry areas that are being irrigated or ready for irrigation can stop irrigation, so as to avoid wasting manpower and financial resources and causing unnecessary economic losses.

2. At present, the value of wheat production is in a critical period. For the fields with poor soil fertility, it is necessary to timely apply fertilizer to ensure the nutrient demand of wheat grouting.

3. Due to the large amount of rainfall in the local area of ​​this precipitation, it is necessary to pay attention to clearing the ditch in time to prevent the waterlogging from affecting the late growth of winter wheat. In addition, the windy weather is likely to cause the winter wheat to fall down. After the rain, it is necessary to check the wheat field in time, and if it happens, it will be timely and righted.

4. At present, in most areas of the province, the reservoirs in the ponds are insufficient or dry, and all localities should use the timing of the precipitation to store more water for the purpose of summer sowing.
