摘要
本文是在前人提出的氯仿熏蒸分解法测定土壤微生物生物-C的基础上,经过对比试验研究的实践,作了适应性的修改。这种新方法可直接应用于酸性土壤微生物生物-C的测定。现暂称之为烘杀抽提容量分析法。该法较之前者更为方便,有效,而且能够大大缩短测定周期。
According to the experiment condacted by combining the extraction method reported in recent years for measuring soil microbial biomass C with the practices of chloroform-fumligation method used in our works, a new method by the way of beat-sterilization, salt-extraction and volumetric analysis for measuring Microbial biomass C in acid soil is suggested. This methed is more convenient and efficient, and the measuring period can be greatly shortened as conpared with the chloroformfumigation method.
