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。

Again, the inhibiting effect on microbial activity is associated with limiting the availability of water for microbial growth.

同时，对微生物的活性的抑制效果与限制微生物对水的利用有关。

This paper addresses some of the issues limiting the development and adoption of microbial inoculants by briefly reviewing the mode of action, inoculant production and performance of several of the more promising organisms that increase availability and uptake of plant nutrients in agriculture.

本文拟通过对能提高作物养分吸收及有效性的几种比较有前途的微生物的作用方式及接种剂生产和效果作一简要回顾，以说明限制微生物接种剂的发展和采用的一些因素。

The positive effects include invert of sugar into alcohol by yeast and invert of malic acid into lactic acid by lactobacillus etc.

摘 要：在整个葡萄酒的酿造生产过程中，不同的微生物起着不同的作用，酿酒酵母将糖转化成酒精，乳酸菌会将苹果酸转化成乳酸等，这些是正常的发酵过程；而醋酸菌会使葡萄酒发生酸败，产膜酵母会使葡萄酒起膜浑浊，霉菌会影响酒的风味等，这些是有害微生物的作用。

The decreasing trends in the size, activity and diversity were also observed with increasing soil depth. Five kinds of plants (Chinese Tamarisk, Reed, Lalang Grass and Capillary Wormwood Herb, Common Seepweed) had obvious positive effects on the microbial communities.

耐盐细菌在耐盐微生物中占绝对优势，放线菌次之，真菌最少；微生物群落具有明显的垂直分布特征，数量、活性和多样性均随土层深度的增加而下降。

Six application rates of lead acetate were added to obtain the Pb concentrations of 0, 100, 300, 500, 700 and 900 mg·kg -1 soil.

结果表明，2种土壤在外源铅含量为100和300 mg·kg-1时，土壤微生物生物量有微小增加，而高浓度铅污染使土壤微生物生物量显著降低。
