| Abstract: | Soil nutrients, microorganisms and enzyme activities in mixed stands of Castanopsis fissa x Pinus elliottii and Schima wallichii x Pinus elliottii were studied. The results showed that compared with pure Pinus elliottii stand, Pinus elliottii mixed stands could increase organic matter content and improve the nutrient status of soil, especially for available nutrients of soil. The amounts of bacteria, actinomyces and enzyme activity in Pinus elliottii mixed stand were higher than those in pure Pinus elliottii stand, whereas their fungi amount was lower than the latter. |
