OBJECTIVE
To study the characteristics of soil microbial variation during Salvia miltiorrhiza crop rotation.
METHOD
the conventional cultivating microbial method was used to study the microbial number and communities structure and soil microbial biomass phosphorus (SMBP) was determined by chloroform vapor extraction method. The data was then analyzed by SPSS software.
RESULT
With the increase of the crop rotation years, the numbers of bacteria and actinomycetes in soil also, but the fungi and SMBP decreased.
CONCLUSION
Microbial mechanism of crop rotation of the planting S. miltiorrhiza is the regulation of microbial number and bacteria physiological communities, the process rebuilds the soil ecological system balance. Microbial communities in soil need at lest 2 years to get to restore, after planting S. miltiorrhiza, which consisting with traditional planting experience.
目的
研究丹参轮作过程中土壤微生物变化特征。
方法
采用常规培养微生物方法研究微生物数量和群落结构，通过氯仿熏蒸提取法测定土壤微生物生物量磷（SMBP）。然后用SPSS软件对数据进行分析。
结果
随着轮作年限增加，土壤中细菌和放线菌数量增加，但真菌数量和SMBP下降。
结论
丹参种植轮作的微生物机制是对微生物数量和细菌生理群落的调节，该过程重建了土壤生态系统平衡。种植丹参后，土壤微生物群落至少需要2年才能恢复，这与传统种植经验相符。
