湖南3种混交林土壤酶活性的差异研究
Soil Enzyme Activity Differences of 3 Types of Mixed Plantations in Hunan
摘要
Abstract
Taking 3 types of mixed plantations soil in Hunan as the research object and 2 types of pure planta-tions of Zelkova serrata and Cunninghamia lanceolata as the control. The activities of soil enzymes such as catalase, peroxidase,protease and urease were analyzed to evaluate the effects of different mixed modes on plantationsland. The results showed that most of the soil enzyme activities had significant differences under different mixed planta-tions mode,especially the surface layer was more obvious. In all mixed plantations mode,the soil enzyme activities of mixed plantations were significantly higher than pure Cunninghamia lanceolata plantations. The rule of soil en-zyme activities in difference soil layers was the surface>middle>lower. In the hill country area,the mixed planta-tions (Cunninghamia lanceolata : Zelkova serrata : Choerospondias axillaris=6 : 2 : 2) had better effect of impro-ving soil enzyme activity.关键词
