摘    要:系统评述了土壤微生物生物量磷的测定方法、含量、周转、C/P及其影响因素.土壤微生物生物量磷周转速度快,是植物有效磷的重要来源,但是易受外界影响,在土壤中含量变化范围比较大.熏蒸提取法是测定土壤微生物生物量磷含量最常用的方法,但是该法对于不同类型的土壤不具通用性.新鲜土样经氯仿蒸汽熏蒸24h,提取效果比较好;不同类型的土壤选择的浸提剂不同,酸性土壤宜用Bray-1提取剂,而碱性土壤宜用Olsen提取剂;转换系数K,亦需根据土壤类型进行校正.未来研究应侧重在几个方面:完善测定方法;土壤微生物生物量磷与土壤供磷能力、土壤磷素转化的关系;形态组成;土壤微生物生物量磷与土壤质量的内在关系.

关 键 词:土壤  土壤微生物生物量磷  熏蒸提取法  研究进展

Abstract:Soil microbial biomass phosphorus(SMBP)is not only an important source of plant available phosphorus,but also one of key biological indexes of soil quality.The aim of this review is to summarize the research results at home and abroad on SMBP.The determination method,contents in soils,turnover,C/P and other affecting factors of SMBP as well as existing problems in SMBP research are included.The SMBP is sensitive to environmental change,so the content is changing in a relatively large range in the soil.The m...
Keywords:soil  soil microbial biomass phosphorus (SMBP)  Fumigation-extraction method  research progress
