固氮菌

The number of bacteria, fungi, ammonifier and nitrobacteria were positively correlated with the biomass of growing roots and absorbing roots, while the number of nitrogen-fixing bacteria was negatively correlated with absorbing root biomass.

细菌、真菌、氨化细菌和硝化细菌数量与生长根和吸收根生物量之间显著正相关；固氮菌则仅与吸收根生物量显著负相关；而纤维素分解菌与根系生物量的相关关系不显著。

The change of remaining litter weight was the largest in the earlier 30 days during 60-day litter decomposition, and there was no significant difference in subsequent 30 days. The phenolic acid content of litter was significantly reduced with the decomposition time prolonging, and the releasing quantity of phenolic acid was the highest at the tenth day. The amounts of soil Aerobic azotobacter, Ammonifier and Aerobic cellulose-decomposer and the soil chemical properties such as pH, phenolic acid content, NH+4-N and available phosphorus were significantly affected by the litter aqueous extract of four decomposition stages.

凋落物分解的60d中，凋落物残留量在前30d内变化最大，30d后无显著变化；凋落物中酚酸含量随分解时间的延长，呈显著降低的趋势，且在分解10d时，酚酸释放量最大。4个分解动态的凋落物浸提液显著地改变了土壤好气性自生固氮菌、氨化细菌、好气性纤维素分解菌的数量和土壤pH值、酚酸含量、铵态氮、有效磷等化学性质。

Nitrogen fixation caused by azotobacter was one of the important origins of nitrogen resources in alpine grassland.

固氮菌的固氮作用是高寒草地土壤氮素的重要来源之一。

In this paper, under laboratory condition , the dynamic influence of both single and combined pollution of carbofuran and cadmium on the number of azotobacter was studied.

本文在实验室条件下，研究了克百威与镉单一及复合污染对土壤中好气性自生固氮菌数量的动态影响。

The physiological properties of azotobacter CN-2 and P-bacteria CP-5 were studied, which are related to mechanism of increasing production on crop.

对生物肥料的供试菌株固氮菌CN-2和磷细菌CP-5进行了与作物增产机理有关的生理特性研究。

It has also been proved that azotobacter CN-2 has a property of secreting hormone material similar to IAA.

固氮菌CN-2还具有分泌吲哚乙酸类植物激素的功能。

Eight methods for the recovery of polyhydroxyalkanoate from the Azotobacter chroococcum G-3 were used to optimize extraction and digestion conditions.

本论文对圆褐固氮菌G—3菌株聚羟基烷酸的八种提取方法进行了优化研究。

N-fixing Azotobacter species have been used as inocula in trialsin Russia, Eastern Europe, and India with inconsistent results.

在俄罗斯、东欧和印度，在试验中固氮菌的一些品种被用来制成菌剂，但效果并不一致。

Bacterial ferritin from Azotobacter vinelandii can directly and quickly pick reduction electrons from a metal platinum electrode or provide electrons to it.

棕色固氮菌细菌铁蛋白能直接快速地从金属铂电极上得到电子或提供电子给铂电极。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
