摘要
同时测定13种不同土壤精氨酸氨化速率、ATP含量、微生物生物量碳和葡萄糖诱导呼吸速率。精氨酸氨化速率0.1~17.1mgNH4-N/h·kg土,与土壤ATP含量、微生物生物量碳和葡萄糖诱导呼吸速率之间,存在极显著的相关性。比起其它土壤微生物生物量分析方法,精氨酸氨化法既简单、快速,又不需要昂贵的设备,可作为土壤微生物生物量测定方法。但是,当土壤含有大量易分解有机物质时,加入精氨酸时,NH4-N产生量极少,多被微生物固定。
Agrinine ammonification rate,biomass C,soil ATP
content and substrate induced respiration were determined in 13 soils.Arginine ammonification
rate was 0 1 to 17 1mg NH 4 N/h·kg soil.There were significant linear relationships between
arginine ammonification rate,microbial biomass C,soil ATP content and substrate induced
respiration.Comparing with other techniques,arginine ammonification technique was much
simpler,faster and cheaper.This technique can be used as a simple technique for estimating
soil microbial biomass except the soil containing high decomposable organic matter.
