Abstract:Studies on soil water holding capacity and soil water supplying capacity of three soils originated from different parent materials, which are called Hongnianni ,Huangjinni,and hongshatu in Chinese, under different utilization styles showed that the general characters of soil water holding and soil water supplying are mainly governed by soil parent material. There are obviously differences of the plant effective soil water content among three soils, and the differences among soils were much more than that among utilization styles. The differences of soil utilization styles change the soil water characters in the low suction stage, and then improved the soil air conditions.
