固氮的

The changes of population density of Rhizosphere bacteria, fungi and actinomyces, and the types and population density of nitrogen-fixing bacteria, phosphobacteria and potassium-bacteria in different types of soils were studied.

研究了不同肥力烟区根际细菌、真菌和根际放线菌的数量变化，以及固氮细菌、磷细菌和钾细菌的数量和种类的变化。

The amount of ammonfying took absolute dominance while that of cellulolytic was the lowest. Aerobe azotobacter played an important role in fixing nitrogen while aerobe bacteria was vital in fibrin-dissolving.

氨化细菌总数处于绝对的优势，纤维素分解菌的数量最少，好气固氮菌在固氮活动中起主要作用，纤维素的分解主要是好气性菌在起作用。

In this paper, based on the research home and abroad, the benefits of ecology, economy, society and their integration of contour hedgerow system of nitrogen-fixing plants in Ningnan County of Sichuan have been analyzed and assessed systematically with analytical hierarchy process.

本文在国内外已有研究基础上，采用层次分析法对四川省宁南县马桑坪的等高固氮植物篱种植模式的生态效益、经济效益、社会效益及综合效益进行了较为系统的分析和评价。

New ideas and technologies in proteomics would impregnate new activities for the development of BNF.

蛋白质组学新思想、新技术的引入，为固氮研究的发展注入了新的活力。

To illustrate how information on an input's value might affect its use, use of nitrogen, phosphorus, potassium, and a nitrogen-providing inoculum on the production of soybean are examined.

为了说明投入值的信息怎样影响其应用，这里对氮、磷、钾和具有固氮作用的接种剂在大豆生产中的施用做了分析。

Industries for production and distribution of legume inoculants containing the nitrogen-fixing soil bacteria rhizobia have been well established for more than 60 years.

在过去的60多年里，建立了生产和销售包含土壤固氮细菌的豆科接种剂的工业。

Soil net N nitrification would increase with the increase of the %FNDA of Lespedeza bicolor. Lespedeza bicolor could fix a large amount of N〓, but was also likely to increase the N leaching loss.

胡枝子固氮作用越强，土壤有机氮的净硝化量就越大，胡枝子在从大气中获取大量〓的同时，很可能会增加氮素的淋溶损失量。

Also,the differences between those in sandy habitat and those in non-sandy habitat are significant.2 There existed two common factors called macroelement factor and trace element factor,which indicate the contents of macroelements and trace elements in the plants respectively.

豆科与禾本科相比，豆科植物因其具固氮能力，所含大量元素水平较高，而禾本科植物因细胞壁硅质化，含微量元素稍高；沙质生境因其养分贫瘠，植物的大量与微量元素均较非沙质生境中的低；特别是本区地带性土壤-栗钙土与特异性生境沙带中的疏林沙土相比，疏林沙土上植物大量与微量元素含量较栗钙土区植物明显偏低。

Biological nitrogen fixation, which provides all the plants on the globe with 75% of fixed nitrogen, is one of the important projects in life science.

生物固氮为全球的植物提供75%的氮素，是生命科学中的重大课题。

Unless they succeed,the yield gains of the Green Revolution will be la rgely lost even if the genes in legumes that equip those plants to enter i nto a symbiosis with nitrogen fixers are identified and isolated,and even if the transfer of those gene complexes,once they are found, becomes poss ible.

除非他们能取得成功，不然的话，绿色革命的产量收益将在很大程度上损失殆尽，即使豆科植物中使这些植物有条件进入到与固氮细菌共生关系的基因可被辨识出来和分离开来的话，且即使这些基因综合体，一旦被发现之后，其移植得以成为可能的话。
