摘要
本文研究不同施肥条件下．土壤微生物生物量的变化，根据实测结果可知，无机肥可使土壤微生物生物量提高，无机有机肥配合使土壤微生物生物量增加较多，直接施用有机肥料可刺激土壤微生物生长．使土壤微生物生物量增加最多。具有发达根系的植物使土壤微生物生物量维持在较高的水平，土壤微生物生物量的变化可做为栽培管理措施对土壤肥力影响的灵敏指标。
Biological mass change of the soil microbes on condition of different fertilizers were studied in this paper,Organic manures could stimulate,and increase greatly microbial Biomass.Cooperation of organic and inorganic fertilizers could show significant effect on soil microbe growth.The plants with much root system could keep the biological mass higher level compared with not croping,The microbial biomass could be regarded as a sensitive parementer in the effect of cultivation and managing measures on soil fertility
