The variance analysis and correlation analysis of the soil moisture content, slope position and aspect of the soil moisture tester by the soil moisture tester showed that the soil moisture content of shrub lands in different slope directions was significantly different, and the slope direction factor was significantly positively correlated with the soil water reserves. . There is no difference in soil moisture reserves between different slope positions. The lowest soil moisture storage on sunny slopes and semi-sunny slopes was Caragana korshinskii. Soil moisture measurements showed that soil moisture consumption of Caragana korshinskii was higher than that of other shrubs; Haloxylon ammodendron and Sassafras tsugae were lower than other shrubs.
Plant roots in deep soil layers are well developed, especially 20cm away from the trunk. The root system is well developed and deep, and can absorb water from deep soil to supplement the water consumption in the 20-80cm soil layer; the soil moisture tester found that the root system is 60cm away from the trunk. Shallow and low density, the water consumption in the soil layer is difficult to replenish from the deep soil, resulting in water absorption in the soil layer and the surrounding soil 20cm away from the trunk, and the root system is deep and dense at 20cm from the base of the trunk, making it from the trunk Soil moisture storage at the base 20cm is greater than 60cm and 100cm; this phenomenon needs further observation and study.
The analysis of the soil moisture tester shows that there are differences in the distribution characteristics of soil moisture levels at different soil depths. In the 0-20cm soil layer, the soil moisture content does not change much with the distance from the trunk, because this depth is a weak layer of soil moisture, and vegetation has little effect on the change of soil moisture content. In the 20-80cm soil layer, the soil moisture meter at the 100cm from the trunk showed the highest numerical content, lowest from the trunk at 60cm, and centered at 20cm from the trunk.
Compared with other shrubs, the transpiration intensity of Caragana korshinskii, Caragana mongolica, and Carassius auratus in the shady slope deserts was lower than that of other shrubs, and the soil water consumption was less. The soil moisture reserves of bells and locusts were lower and the soil water consumption was greater. The study of soil moisture tester showed that the transpiration intensity of Caragana kansui in semi-shaded slope was lower than that of other shrubs, and the soil water consumption was less; the transpiration intensity of half-day flower was greater and the water consumption of soil was greater.
