The aims of this project were to establish the determination method of microbial biomass C and N and to clear their metabolism in rhizosphere soil of upland crops.(1985): A close relationship between ATP content by TEA-NRB method and biomass C by chloroform fumigation method was obtained, and the calculation factor of 870 was proposed to convert the ATP content into soil microbial biomass C.(1986): The determination method of microbial biomass N in rhizosphere soil of upland crops was examined. It was indicated that the chloroform fumigation-incubation method and the direct extraction method of biomass N just after the fumigation were available to measure the biomass in rhizosphere. Changes in biomass C in rhizosphere soil during the growing season of upland rice was measured.

本课题旨在建立高地作物根际土壤微生物量碳、氮的测定方法，明确其代谢规律。（1985年）：结果表明，TEA-NRB法测定的ATP含量与氯仿熏蒸法测定的生物量C之间存在密切的相关性，并提出将ATP含量换算为土壤微生物量C的计算因子为870。（1986）：对高地作物根际土壤微生物量氮的测定方法进行了研究。结果表明，氯仿熏蒸-培养法和熏蒸后直接提取生物量氮法是测定根际生物量的有效方法。测定了高地生长季根际土壤生物量碳的变化。
