4Relation between siol microbial diversity and enviromental facters There is a moderate relationship between Soil microbial diversity and organic matter;and a week relationship between soil microbial diversity and soil moisture.

4土壤微生物多样性与环境因子的关系土壤微生物多样性与土壤有机质之间存在中度相关关系；与水分之间的关系表现为弱的相关关系，与植物群落呈负的弱相关。

The results showed that soil microbial numbers and biomass in Leymus chinensis and Stipa grandis grassland were higher than those were in degenerative Artemisia frigida and sandy rare-tree grassland significantly.

典型草原不同生态分布类型的土壤微生物量大小有显著不同，土壤微生物的数量与生物量的分布规律基本一致，且与土壤有机质的分布相关联。

The effect of lead treatment on the soil microbial biomass carbon, microbial biomass nitrogen, micro-bial activities, rice physiological indices and rice biomass in the interactive system of soil-rice-lead and microbe, were studied by a greenhouse pot experiment. Lead was applied at six different levels in two different paddy soils, namely 0, 100, 300, 500, 700 and 900 mgkg^(-1) soil.

盆栽试验研究了土壤－水稻－铅－微生物相互作用的体系中，外源铅不同处理水平CK、100、300、500、700、900mgkg^(-1对两种水稻土壤微生物生物量碳、氮，微生物活性，水稻生理指标及生物量的影响。

Furthermore, rhizosphere effect of plants on soil microbial community construction was also found.

研究结果表明，栽培年限对根际土及根围土中的微生物种群结构有显著影响；人参和西洋参栽培土壤中的微生物种群结构也存在差异；寄主植物对土壤微生物种群结构的影响表现有根际效应。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
