ABSTRACT
In order to explore the physical properties of the soil in different land use patterns. In this paper,
the rhizosphere and non-rhizosphere soil under different land use patterns (Uncaria rhynchophylla
base, forest land and wasteland) in Uncaria rhynchophylla-producing areas of Jianhe County, Guizhou
Province were studied, and the distribution characteristics of soil physical indexes under different
land use patterns and their correlations were studied. The results showed that there were significant
differences in soil physical properties between rhizosphere and non-rhizosphere under different land
use patterns. Compared with forest land and wasteland, Uncaria rhynchophylla base can significantly
increase the soil water content, soil capillary porosity, and significantly reduce the soil bulk density.
The rhizosphere soil water content was as follows: Uncaria rhynchophylla base (21.09 g/cm3) < forest
land (20.19 g/cm3) < wasteland (19.19 g/cm3); The variation of soil capillary porosity was as follows:
Uncaria rhynchophylla base (45.04 g/cm3) > forest land (31.37 g/cm3) > wasteland (22.51 g/cm3). Most
of the physical indexes of rhizosphere and non-rhizosphere soil in forest land and wasteland showed
weak significant correlation. The correlation of soil physical indexes in wasteland is weak, and the
correlation between soil water content in rhizosphere and soil capillary porosity is strong. Different
land use patterns have a great impact on soil physical indexes, so the role of land use pattern should be
considered in the process of Uncaria rhynchophylla planting.
