固氮作用

This system raised soil fertility and soil productivity through increased biological nitrogen fixation and by providing cattle manure.

这一体系通过豆科作物的生物固氮作用和牛粪还田使土壤肥力和土壤生产力得到提高。

To be hosts for nitrogen-fixing bacteria.

这其中的一个新颖思想就是，在植物的染色体内注入并非是该植物自然构造一个部分的那些不相关联的因基：具体而言，这一思想是，在非豆科植物内注入这样一些基因，倘若这些基因可被辨识出来并被分离开来，而这些基因业已使豆科植物宜于充当那些具备固氮作用的细菌的寄主。

One such novel idea is that of inserting into the chromosomes of plants discrete genes that are not a part of the plants' natural constitution; specifically, the idea of inserting into nonleguminous plants the genes, if they can be identified and isolated, that fit the leguminous plants to be hosts for nitrogen-fixing bacteria.

The swainsonine mainly originated from the metabolism of Oxytropis endophyte, and its concentration was related with the nitrogen fixation of nodule, but not genetic characteristics.

棘豆中苦马豆素主要来源于内生菌的代谢产物，其含量与根瘤菌固氮作用有密切关系，而与遗传无关。

The 0-40cm soil layer soil mean value looked that mixes by the interlacing broadcasts the lawn soil ulmin, the alkaline hydrolysis nitrogen content to be highest; The fast-acting phosphorus, the fast-acting potassium are highest by the unicast awnless brome lawn content; The colleague mixes broadcasts lawn pH to be biggest.

无芒雀麦对土壤要求不严，耐贫瘠、严寒，耐碱性也较强，需氮较多，适宜与紫花苜蓿、沙打旺、野豌豆、百脉根、红三叶等豆科牧草混播，借助豆科牧草固氮作用，促进无芒雀麦良好生长[4]。本实验就是无芒雀麦单播草地和与紫花苜蓿混播草地对土壤理化性质的影响进行比较。

Research areas include biological nitrogen fixation in sustainable production, nutritional value of clover and grass, plant pathogens and overwintering problems, feeding hygiene etc.

研究领域包括可持续生产的生物固氮作用、苜蓿和草的营养价值、植物病原体和越冬问题以及饲养卫生学等。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
