对８ 种肥力水平差异较大的红壤进行了微生物量磷与土壤磷之间的相关性研究⒚结果表明，红壤微生物量磷与土壤全磷、土壤有机磷以及土壤速效磷之间存在明显正相关⒚红壤微生物量磷尤以与土壤速效磷关系最为密切，提示两者之间存在某种动态平衡；同时，要提高红壤固定磷的利用率，可通过刺激土壤微生物的生长，促进微生物对红壤磷的周转和循环来实现⒚ The results showed that there was a significant positive correlation between microbial biomass P and soil total phosphorus, soil organic phosphorus and soil available phosphorus in red soil with eight different fertility levels. The soil microbial biomass phosphorus in red soil is especially closely related to soil available phosphorus, suggesting that there is some dynamic balance between the two. At the same time, in order to increase the utilization of fixed phosphorus in red soil, it can stimulate the growth of soil microorganisms, Turnaround and recycling to achieve ⒚
