The results showed that methamidophos inhibited the growth and activity of bacteria, Actinomyces and Azotobacter at different degree, but stimulated the growth of fungi; the results also showed that soil respiration and ammonification was stimulated, however, soil nitrogen fixation, nitrification and Fe－reduction was inhibited.

结果表明，甲胺磷对细菌、放线菌和固氮菌群的生长具有不同程度的抑制作用，而对真菌却有一定的刺激效应；土壤的呼吸作用、氨化作用增强，自生固氮能力、硝化作用以及铁离子价数转换作用减弱。

This character will be useful for cooling requirement of HTSC. Based on the experiment, a novel configuration of the pulse tube refrigerator with a build in frozen cryogen accumulator is proposed as an example of possible applications.

由于氦氮混合工质中固氮组分的出现，使得制冷机在关机后依旧可提供一段时间的稳定温度平台，这一特性将在诸如高温超导器件的冷却等方面具有潜在的应用价值。

It must be emphasized that performance of inoculant and the amount of N legumes derive from BNF is directly linked to crop management including application of N fertilizer.

必须强调的是，接种物的表现和豆类作物从生物固氮获得的氮量与包括施用氮肥的作物管理直接有关。

Anyway our present investigation on the occurrence of of nodulin homologs in rice may provide clue to the nitrogen-fixing potential of rice.

我们对于水稻中存在的结瘤素基因的同源基因研究，将为水稻结瘤固氮潜能的研究提供更多的线索。

And nodulation genes. We are interested in t he studies of int eraction between two symbiotic partner in

本实验室研究工作的主要方向是研究固氮基因、结瘤基因的结构和调节的分子机理，我们的兴

Purpose of the experiment was searching for the method of cutting reproduction of Elaeagnus mollis., providing a foundation for the clonic selection in the wild population, and offering sufficient quantity of clone stocks for studying the relation between growth and nitrogen—fixing root tubercle bacteria.

本试验的目的是研究翅果油树扦插繁殖方法，在其野生群体中进行无性系良种选育的效果，以及翅果油树生长与固氮根瘤菌之间的关系，为接种■氮根瘤菌提供足够数量的无性系苗木。

Seed yield, nitrogen accumulation and BNF by nodulated soybeans growing in a very P-deficient soil increased dramatically with P inputs.

在非常缺磷的土壤上生长的结瘤大豆的籽粒产量、氮积累量和生物固氮量均随增加磷的投入显著增加。

Nitrogenase activity of nitrogen-fixing bacteria was measured by acetylene reduction assay combined with gas chromatography.

运用乙炔还原法测定了固氮细菌的固氮酶活性，通过测定菌落周围产生的透明圈和混浊圈大小对磷细菌的溶磷活性进行比较，采用火焰分光光度计测定了钾细菌的解钾活性。

Makes the decency coal, the pearlite and the vermiculite carries on between the root nodulebacteria and the alfalfa variety match as the matrix, alfalfas nitrogen fixation effect and thegrowing trend is higher than other two kind of matrix, the decency coal may first take the highlyeffective strain screens matrix.

以风化煤为基质进行根瘤菌与苜蓿品种之间的亲和性的匹配试验中，苜蓿的固氮效果和长势均高于珍珠岩和蛭石这两种基质。因此，风化煤可优先作为高效菌株筛选的基质。

In this study, NBPT mixed proportionally with urea and NBPT without urea were applied to the soybean plants to analyze the effect of NBPT on the soybean root growth in root vigor, root nodule number and weight, and the activity of nitrogen fixation of root nodule.

为探索利用NBPT提高大豆生长发育的途径，对施用NBPT的大豆，利用氧化还原法，乙炔还原法和凯氏定氮法分别测定了大豆根系活性，根瘤固氮活性和植株含氮量，并测定了大豆根瘤的数量和重量。
