| Abstract: | An experiment was conducted to determine soil nutrient contents in a pure Pinus yunnanensis forest,a pure Alnus nepalensis forest and a mixed forest of P.yunnanensis-A.nepalensis.And nutrient contents of leaves and fine roots of P.yunnanensis and A.nepalensis were also studied.Results showed that the contents of soil organic matter,available phosphorus,hydrolyzable nitrogen,available potassium,total nitrogen,total phosphorus,total potassium,exchangeable calcium and magnesium in the soil of the mixed forest ... |
