土壤微生物

Hence,in this study, the change of soil microbial communities were investigated through direct current field ,which is supposed of provide a theory basis for soil electrokinetic bioremediation technology.

而电场作用下土壤微生物群落的变化与利用电场生物修复效率密切相关，本文鉴此研究了直流电场作用下对土壤微生物群落多样性的变化规律，以期为电动生物修复技术的应用提供了一定的科学理论依据。

The results show that the combined application of organic fertilizers could control three kinds of the soilborne diseases,such as tomato bacterial wilt,Fusarium wiltFusariu...

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。

The results indicated that organic fertilizer at a rate of 75000 kg/ha or organic fertilizer (75000 kg/ha) with compound fertilizer at a rate of 300 kg/ha had higher effects on genetic diversity of soil microbial community under field conditions. Treatment of fertilizers as base application at level of 600 kg/ha resulted in decrease of DNA sequence richness index and diversity index of soil microbial communities, and the similarity coefficient of DNA sequence from soil microbial communities was the lowest compared with control. Organic fertilizer treatment was conducive to increasing DNA sequence diversity index and evenness index of soil microbial communities.

结果表明，在本试验条件下，基肥为75000kg/hm^2有机肥处理和75000kg/hm^2有机肥加300kg/hm^2复合肥处理最好；基肥为600kg/hm^2复合肥处理使土壤微生物群落DNA序列丰富度指数和多样性指数显著下降，与对照的DNA序列相似系数最低；有机肥处理有利于土壤微生物群落DNA序列多样性、均匀度和黄瓜产量的提高。

Total amount of microbe in polluted soil was also more than that in normal soil.

污染土壤中微生物的数量高于无污染土壤微生物的数量。

The relationship between soil microbial number and organic matter, total N, available N, and available P of soil samples, and the ecological effect of soil microbial physiological community participating nitrogen cycle in this area were also discussed.

同时讨论了土壤微生物数量与土壤有机质、全N、有效N和速效P的相关性及微生物生理群在该场区氮循环中的生态作用。

However, only about 1% of soil microbes are cultivable with traditional techniques, others are all uncultured microorganisms.

摘要摘要：土壤是微生物最重要的生境，土壤微生物具有极大的多样性。

Only about 1% of soil microbes are cultivable with traditional techniques, others are all uncultured microorganisms.

土壤是微生物最重要的生境，土壤微生物具有极大的多样性。

In order to investigate the succession of soil microbial community with ecosystem development, soil samples of three successional stages (i.e., barren stage, cryptogamic crust stage and herbaceous vascular plant community stage) from two tailings wastelands (Yangshanchong tailings wasteland discarded in 2001 and New Tongguanshan tailings wasteland discarded in 1991) were collected and soil microbial biomass was determined by methods of typical plate culture' and molecular biology.

该研究以2处（即，铜陵杨山冲尾矿废弃地和铜官山新尾矿废弃地）不同时期弃置的、处于3个演替阶段（原生裸地阶段、隐花植物结皮阶段和草本维管植物群落阶段）的铜尾矿废弃地为研究对象，利用传统培养法和分子生物学法相结合的手段对土壤微生物量和土壤微生物群落结构变化及其影响因素进行了调查。

However, only about 1% of soil microbes are cultivable with traditional techniques, others are all uncultured microorganisms.

土壤是微生物最重要的生境，土壤微生物具有极大的多样性。

The analysis of diversity shows that some of the manuring treating will advance the soil bactrial community diversity index, evenness and richness which was high from the sample without manuring. Different manuring could increase the soil bactrial community parameter effectively but discrepantly.

多样性分析显示，部分施肥土壤的微生物群落多样性指数、均匀度指数和丰度均高于对照，处理间的各土壤微生物群落参数差异较大。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
