The main limiting factor for the recovery of plant growth in the Loess Plateau is the effect of water in the soil. The key to the spatial variation of soil moisture in the loess region lies in the rational allocation of vegetation and effective utilization of soil moisture. The study of soil moisture tester shows that the slope direction, slope, and slope position of the slope scale soil moisture distribution at different levels, the influence of different plant species, and the vertical and horizontal distribution and time distribution of soil moisture have different effects. However, the laws of soil moisture change are less studied in the western Loess Plateau.
Using a combination of a soil moisture tester and a drying method (105°C) to calibrate the neutron meter, the neutron meter is calibrated as a volumetric water content, and the mass water content measured by the drying method is multiplied by the soil bulk density (the bulk density is determined With the ring cutter method, it is also converted to volumetric water content. When the soil moisture tester was first measured, the drying method was used. Afterwards, it was measured with a neutron meter. Each layer was repeated 3 times and the average value was taken. The sampling time was August when the plant growth was relatively stable.
The relationship between soil moisture and aspect The data of soil moisture reserves of each sample were grouped according to the four orientations of sunny slope, semi-sunny slope, shady slope, and semi-shaded slope, and the mean value of soil moisture reserves of different slope directions could be obtained. The results of the soil moisture tester showed that the Yangpo slope had the lowest water storage capacity, the Yinpo slope had the highest water storage capacity, and the semi-sunny slope and the semi-shade slope were centered.
Through the above analysis of the soil moisture tester, we can see that in a certain range of slopes, the main influence of soil moisture content is the direction of slope development. The light intensity of slopes and slopes is large, and plant transpiration and soil water evaporation and transpiration are strong. The weak light intensity of shades and shady slopes, soil water evaporation and transpiration intensity are small. Therefore, the highest soil moisture storage is on the slope, followed by the semi-shaded slope, and the slope and slope are the lowest.
