After the wheat emerged, the high temperature in most parts of the province and the precipitation continued to be low, and the soil moisture and drought management system analyzed the drought conditions in West Henan, Henan, Henan, Henan and other regions. The phenomenon of seedling ridges and ridges occurs and has an adverse effect on the growth of wheat seedlings. Soil moisture content in some areas is always at a low level, which is not conducive to the cultivation of strong seeds before winter.
In the late winter, the temperature of the whole province is low, but the temperature is stable and the amplitude is not large. Because the growth of the wheat is slow and the water is less during this period, the unfavorable moisture condition has little effect on the growth of wheat and is conducive to safe wintering. The soil moisture and drought management system results showed that soil moisture content was adequate in most parts of the province, except for a few land masses in northern Henan and western Henan, where soil moisture content was between 66% and 85%. Appropriate lyrical conditions are favorable for the delivery and growth of wheat before winter.
Soil moisture content and drought management system measured the relative water content of 0-20cm soil layer increased by 2.14 percentage points, and the relative water content of 20-40cm soil layer increased by 2.17 percentage points. Compared with the same period of the previous year (see Figure 2-2), the average relative water content of the 0-20cm soil layer at the monitoring point of the soil moisture and drought management system in the province was 7.25 percentage points higher than the mean value of the relative water content of the 20-40cm soil layer. 2.09 percentage points.
From the overall analysis of the soil moisture and drought management system, most of the wheat crops in the returning green season were significantly better than the same level in the previous year, which provided sufficient conditions for the growth of the winter wheat to its jointing stage; When wheat is sowed at the end of the crop, the site preparation is extensive, and the rain and snow in the middle and mid-February are less and the soil loses moisture quickly. Therefore, the output will be affected by the shortage of tillers and spikes in the later period.
