| Abstract: | Objective] The research aimed to provide theoretical references and scientific basis for the ecological environment construction and conversion of cropland to forest of Three Gorges Reservoir. Method] The soil sample of different age and depths conversion of farmland to planted tea in Zigui was choosed and the content of soil available P and microbial biomass P was analyzed. Results] The content of soil available P increased gradually and soil microbial biomass P increased firstly and decreased following.Soil available P and microbial biomass P decreased both with increase of soil deapth.Conclusion] The growth of tea tree was advantageous to the accumulation of P in the surface of soil and the improvement of soil quality. |
