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.
