中国东南部红壤旱地种植系统的生物学及其应用研究——Ⅵ 红壤果园土壤酶活性与土壤微生物生物量研究初报

STUDIES ON THE BIOLO GY AND THE APPLICATION OF THE CROPPING SYSTEM ON THE UPLAND RED SOIL IN SOUTHEAST CHINA——Ⅵ. Preliminary studies on the activity of soil enzymes and soil microbial biomass of orchards on the upland red soil

本研究对红壤果园土壤微生物生物量与土壤酶活性进行初步分析,表明随着红壤果园利用年限的增长,土壤酶活性与土壤微生物生物量显著提高,过氧化氢酶、转化酶、脲酶的活性与土壤微生物生物量可以表征红壤旱地熟化程度与肥力水平。

This paper deals with the soil microbial biomass and the activity of soil enzymes of orchards on the upland red soil. Analysis shows that the activity of soil cnzyrnes and soil microbial biomass increase with the years of cultivation of the orchards. Therefore, the activity of catalase, invertase, urcase and soil microbial biomass can symbolize the level of the soil fertility.
