根瘤菌

To study the diversity and phylogeny of Rhizobia strains from Sesbania cannabina in Jinshajiang arid river valley in Sichuan province, China.

揭示金沙江干热河谷区这一特殊地理环境下田菁根瘤菌的多样性和系统发育地位。

Tropici was below 90%. Rhizobia of Sesbania cannabina in Jinshajiang arid river valley are highly diverse, they are closely related to Rhizobium, Sinorhizobium and Agrobacterium.

金沙江干热河谷区田菁根瘤菌具有较为丰富的多样性，在系统发育地位上分布于Sinorhizobium、Agrobacterium和Rhizobium三个属。

Rhizobium A spherical or rod-shaped nitrogen-fixing bacterium that can live either freely in the soil or symbiotically in the root nodules of leguminous plants and a few other species ,such as alder.

根瘤菌属：一种球形或杆状的固氮菌，可以在土壤中独立生存，也可与豆科植物和其他的植物如赤扬共生。

Tephrosia vogelii is all treasures, not only can extract the root, stem or leaf to rotenone, but not strict on the environment, can make use of sloping land, wasteland cultivation, the roots contain rhizobia, can be free of fixed nitrogen in the air, can play to improve The role of the soil.

非洲山毛豆浑身是宝，不仅其根茎叶皆可提取到鱼藤酮，而且对环境要求不严，可利用坡地、荒地种植，其根部含有根瘤菌，可以固定空气中的游离氮，可起到改良土壤的作用。

Rhizobia populations in soils are composed of many strains and, in some soils, many species.

土壤中根瘤菌群体由许多菌株组成，在一些土壤中有许多种。

Number of effective rhizobia in the soil at planting

播种时土壤中有效根瘤菌的数量

Thus, the infrared spectra analysis can reflect the relationships of rhizobia, but in practice, there were some difficulties.

因此，红外光谱分析在一定程度上可反映根瘤菌的分类地位，但实际应用起来，仍有一定的困难。

This effect of mineral N assumes there is adequate numbers of effective rhizobia available to the crop to maximize BNF.

矿质氮的这种效果是假定有大量的有效根瘤菌可使作物的生物固氮达到最大。

These results indicated that 92 strains of soybean Rhizobia isolated from one soil type in Honghu County exhibited a great variation.

以上研究结果表明，生活在同一小样本土壤中的大豆根瘤菌也存在丰富的遗传多样性。

The symbiosis formed by rhizobia and legume host plays an important role in agriculture.

根瘤菌与豆科植物形成的共生固氮体系在农业生产中具有重要作用。

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.
