Shanxi South Winter Wheat is about to return to green, wheat irrigation needs to prevent phlegm and freeze overnight

According to the survey data of the thawed meteorological observatories (10 in southern part of Shanxi Province) on February 8 (the soil in most stations in the north and south-central areas is still frozen), most of the counties (cities) in the south have light soil layers. To moderate drought, some counties (cities) have 1 to 3 cm of dry soil; the bottom is better than the table, and most of them are suitable. After the test on February 8, the province's general decline was small to medium snow, local snowfall, snow in some counties (cities), which is conducive to the increase of soil moisture, but the precipitation in Yuncheng is less, and the drought will continue.

0~20cm: The relative humidity of the county (city) in Houma, Xinyi and Hepinglu in the south is between 40% and 50%, and it is in moderate drought state; Hejin, Wenxi, Lushan, Yuanqu and Salt Lake in the south The relative humidity of the districts and counties (cities) is between 50% and 60%, which is in a slightly dry state; the cities and towns such as Yucheng and Linyi are in a state of approximation.


20~50cm: The relative humidity of the county (city) in the south is 50-50%, which is in a mild drought state; Hejin, Houma, Xinyi, Pinglu, Salt Lake District, The counties (cities) such as Yucheng and Linyi are in a proper state.


In the next few days, the province's province is dominated by cloudy weather on sunny days, accompanied by snow or light snow, which has little effect on drought relief. As the winter wheat in the southwestern part of the mountain is about to enter the greening period, the current drought is not good for its smooth return to green. Therefore, it is suggested that the southern wheat area should do a good job of winter wheat irrigation and drought relief according to the temperature and lyric conditions to ensure the smooth return of winter wheat. When irrigating, it should be noted that the soil should be completely irrigated before irrigation, so as to avoid freezing and freezing, so that the wheat is subjected to freezing damage.

The specific forecast is that during the day of February 11th, the whole province is cloudy with cloudy days; during the day of February 11th~February 12th, the province is sunny and sunny, and there are small snow in parts of the west; February 12th~February 13th daytime The province is cloudy and cloudy, with light snow; February 13th to February 14th during the day: the province is sunny and cloudy; February 14th to February 15th during the day: the province is cloudy and sunny; February 15 Daytime ~ February 16 Daytime: There are snow in parts of the north and central part of the province, and 4~5 northwest winds in the north central part; February 16th to February 17th day: the whole province is cloudy and sunny .
