土壤微生物

The changes of Cr and Fe concentration were measured during Co-culture experiment and slurry experiments. The microbial reducing ability of different chromate concentrations and the effect of chromate on dissimilatory iron reduction in paddy soil were investigated.

通过接种土壤微生物的混合培养及土壤泥浆培养试验，测定了厌氧培养过程中Cr和Fe浓度的变化，研究了不同浓度铬酸盐的微生物还原能力及不同浓度铬酸盐对水稻土中氧化铁还原的影响。

The microbes dynamics rule during tobacco life cycle in various types of soil might be a new consideration to understand the development of especial features of flue-cured tobacco. soil type ; edaphon ; dynamics ; flue-cured tobacco

因此加强对土壤微生物种群与土壤类型之间在烟叶生长期的相关规律研究，可以丰富烤烟根际微生态方面的内容，并为研究烤烟根际微生物与优质烟叶生产之间的关系，以及这种关系对烤烟产量品质的影响提供理论基础。1材

At the same time, a continuous restraint on the edaphon, including those existing in the tested roots will happen when 50g wood vinegar are added into 1kg organic manure and 30kg soil.However, the influence of pyrolignerous acid and guaiacol were not same with wood vinegars. The reason that wood vinegars can much active the edaphon effectively, is not only the pyrolignerous acid or guaiacol reacted.

此外，通过采用木醋液中的两种主要成份醋酸与愈创木酚对比试验，表明其对土壤微生物数量的影响与木醋液不相关，木醋液能起到增加土壤微生物数量的作用，虽然有可能是其他物质在起主导作用，但更有可能的是多种物质的综合作用。

Microbial population changes in farmland soil of different aged H. lupulus was investigated, and microbial number and diversity index in soil of different aged H.

通过测定22，20，18，8和5年啤酒花农田土壤微生物区系的变化，分析了不同植龄土壤微生物数量及多样性指数与啤酒花产量和品质的关系。

With the study of temporal-spatial distribution of siol microbial diversity,we found species richness index,diversity index and evenness index had a falling trend,and the downtrend was slighly different.

在研究土壤微生物的时空分布中发现，土壤微生物现物种丰富度指数、多样性指数、和均匀度指数随海拔升高，都呈缓慢下降趋势，并且在不同地区下降趋势略有差别。

The paper deals with the effect of long-term fertilization and mulching on the functional diversity of soil microbial community using Biolog technique.

应用Biolog技术探讨了不同施肥处理与地膜覆盖对土壤微生物功能多样性的影响，从微生物功能多样性的角度评价施肥与地膜覆盖对土壤质量的影响。

Other methods such as Biolog GN analysis,phospholipids fatty acids analysis and nucleic acid-based analysis can be used to study and characterize soil microbes which currently cannot be cultured,a...

使用Biolog分析、磷脂脂肪酸分析和核酸分析等方法，可研究和表征那些现在还不能够被培养的土壤微生物，从而获取关于土壤微生物群落多样性的更多和更完整的信息。

The soil microbial community structure is improved with the application of organic manures. AWCD and Shannon index of soil microbial communities are greatly related to the incidence of the diseases.

土壤微生物群落的AWCD和Shannon index与作物发病情况有较好的一致性，显示施肥提高土壤微生物多样性，对土传病害的防治有重要的影响。

In order to maintain its normal life activity in adverse circumstance, the microorganism can strengthen its metabolizing intensity.

从本研究的结果及前人的研究结果来看，重金属污染胁迫下土壤的微生物生态效应，在土壤微生物生物量、生理生化代谢活性、种群结构及其动力学特征以及生物修复的机理等基础理论和应用研究上取得了一定的研究成果。

Comparing with traditional cultivation system (two seasons planting cucumber with fallowing in summer), planting leafy vegetable anti garlic in summer increased the yields of the two crops anti the soil microbial biomass carbon content, total microbial population, and sucrase activity, decreased the amounts of soil nematode and root-knot nematode, and maintained a relative high Shannon-Weaver index. Planting crown daisy, garlic, and spinach in summer increased soil sucrase activity by 8.9%, 89.5%, and 36.9%, and the planting of crown daisy and garlic also increased the Shannon-Weaver index by 7.7% and 9.4%, respectively.

结果表明：夏茬休闲期种植速生叶菜和青蒜增加了土壤微生物量碳含量、微生物总量和蔗糖酶活性，维持了较高的Shannon-Weaver指数，减少了线虫和根结线虫的数量，增加了各茬作物产量，夏茬种植茼蒿、菠菜、青蒜后土壤蔗糖酶活性分别增加了8.9%、36.9%和89.5%，夏茬种植茼蒿和青蒜后Shannon-Weaver指数分别提高了7.7%和9.4%。

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。
