摘要
针对哈尔滨黑土28a长期定位施肥现状进行土壤生理转化菌群测试分析,采用稀释平板法和MPN法测定不同施肥处理土壤的微生物各生理群的数量。结果表明:施肥处理的土壤微生物多样性指数最高,微生物种类多,群落结构较复杂,同不施肥处理之间的土壤微生物群落结构组成存在显著差异。
The paper investigated the analysis soil physiology transformation bacterium aiming at the status of long-term located fertilization on black soil for 28 years in Harbin city. Using diluted plate and MPN method to mensurate different fertilization treat- ment of soil micro-organisms.The results showed that: the treatment of fertilization has the highest multiform soil microorganism in the experimentation and different kinds of microorganisms, and it has remarkable difference with the different treatments in the soil microorganism community configuration.
