摘要:Abstract: Vegetation types have important effects on soil moisture. Vegetation and soil moisture has certain feedback mechanism. To investigate the influence of different vegetation processing method of subtropical red soil water content, through the PR2 moisture meter type profile, we measured 100 - 400 mm soil volumetric water content of four types of test samples (Bare area, Cynodon dactylon strip covering, Cynodon dactylon over covering, Citrus net tillage) under different weather. The results show that: 1) Under the condition of drought and rainfall, the soil moisture content at the depth of 100 mm was the highest in the region of Cynodon dactylon strip covering ; 2) At the depth of 200 mm and 300 mm, the soil moisture content was the highest in the whole orchard, but the soil moisture content was the highest under the condition of strong and urgent rainfall in 300 mm; 3) The soil moisture content at the depth of 400 mm in each plot was higher than which of the 100 mm, 200 mm and 300 mm. It was still the highest in the whole orchard region at the same depth, which showed that the soil moisture in the shallow layer increased with the depth of soil layer; 4) Variance analysis showed that the Cynodon dactylon strip covering had a significant difference compared with other areas, which explained that Cynodon dactylon strip covering could significantly increase the soil water content. The research results could be used to provide a scientific basis for soil and water conservation in subtropical red soil.
