土壤磷(P)分级方法的新进展,使人们有可能较深入的了解磷在土壤中发生的各种转化过程。采用直接测定微生物含磷量的方法,现已可以对微生物作为植物的磷源和磷的贮藏库以及磷在土壤中重新分配的途径方面起的作用作出评价。本文的目的是对发生在根际的机物和微生物群落之
New advances in soil phosphorus (P) classification methods have made it possible to gain a deeper understanding of the various transformation processes that occur in the soil. The method of direct determination of the phosphorus content of microorganisms is now available to evaluate the role of microorganisms as a reservoir of plant sources of phosphorus and phosphorus, and as a means of redistributing phosphorus in the soil. The purpose of this paper is to study the organisms and microbial communities that occur in the rhizosphere
