3. Rizhao The sunshine hours in eastern Inner Mongolia and Xilin Gol League are 62-117 hours, and the percentage of sunshine is 44%-81%. In other areas, the sunshine hours are 33 to 81 hours, and the percentage of sunshine is 24% to 59%.

4. Compared with the same period of the previous year, the number of windy days in the strong winds is close to normal or less than one to two days in most parts of Inner Mongolia.

5. From the 14th to the 15th of the rainstorm period, there were 50-82mm heavy rains in Kaqi and Ningcheng, Chifeng City, Inner Mongolia, and Tuo County, Hohhot City.

Second, soil moisture analysis

1. Soil moisture measurement and analysis

In the middle of Inner Mongolia, the situation in the central and western parts of Inner Mongolia increased significantly, and the situation in the north-central part of the central and eastern regions decreased slightly. At present, the area of ​​public opinion of Class I and above, Class II, Class III and below is 23.9, 71.9 and 185,000 square kilometers respectively, accounting for 20.9%, 62.9% and 16.2% of the total area respectively; compared with the same period of last year. The area of ​​the first type decreased by 149,000 square kilometers, the area of ​​the second type increased by 395,000 square kilometers, and the area of ​​the three types of concrete decreased by 246,000 square kilometers. Compared with the first half of August, the area of ​​the first type decreased by 112,000 square kilometers. The area of ​​the second type of plutonium increased by 500,000 square kilometers, and the area of ​​the three types of plutonium decreased by 388,000 square kilometers.

2. Soil moisture prediction

It is expected that in the next five days, there will be uneven distribution of small showers or small thunderstorms in Inner Mongolia, and moderate rain in the south-central part of the central and western regions. Due to the lack of precipitation in the next five days, soil moisture in most areas of the region will decline. trend.

3. Important weather events and their impact on agricultural and livestock production

In the first ten days, the southern part of Xing'an League and the northeastern part of Tongliao City suffered from drought due to less precipitation, mainly affecting corn grouting. Most of the central and western regions were affected by precipitation from 13 to 16 days, and the drought has eased.

The precipitation weather process within ten days effectively increased soil moisture and eased or relieved the drought in the central and western agricultural areas. At present, most of the corn in our area has entered the stage of milk ripening. The suitable precipitation and temperature are conducive to corn filling and maturity. Most of the agricultural meteorological conditions in the eastern area are conducive to the growth and maturity of the corn stage. The potato is in the stage of tuber growth, and the suitable soil moisture condition is the key factor determining high yield. The effective precipitation on 13-16 days has a certain effect on the tuber enlargement. Low-lying land with excessive precipitation should strengthen drainage and ventilation to prevent premature senescence of the roots and reduce production.
