- Abstract:
-
Local poplar branch was selected as amended materials, and simulated experiment with five amended patterns including mulching unground branch (UBM), mulching ground branch (GBM), incorporating ground branch(GBI), incorporating ground branch plus mulching unground branch (GBI+UBM), and control (CK) were designed for testing changes of C, N, P, K, bulk density, field water holding capacity, porosity, soil moisture content, microbial number and enzyme activities of desertification soil in Ningxia. The results showed that compared with CK, GBI and GBI+UBM significantly decreased bulk density, but increased soil total porosity, field water holding capacity, P, inorganic N, K, bacteria number, actinomyces number, fungi number, microbial biomass C and microbial biomass N, urease activity and cellulose activity (p < 0.05), and GBI+UBM was more effective than GBI (p < 0.05). However, UBM and GBM merely increased soil moisture content,actinomyces number and there no different between them(except soil moisture content). PCA showed the amended effects among treatments followed the order:GBI+UBM > GBI > UBM > GBM > CK. This study provides a successful case for sandy soil improvement in Ningxia and other arid and semiarid areas of North China.
