固氮作用

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。

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。

While two herbicides had no significant effects on the growth of three cyanobacteria at low concentrations (0.01~0.001mg/L), they made damage to cells and affect cyanobacteria's growth at high concentrations (10~100mg/L). EC_(50) values of three cyanobacteria were showed below: Anabaena azollae, 3.172 mg/L; Anabaena azotic, 3.654 mg/L and Anabaena flos-aquae, 3.377mg/L Nitrogenase activities of three species also showed different tolerant capabilities to the two herbicides under 10% vol.

在低浓度(0.01~0.001mg/L)的2种除草剂的作用下，3种固氮蓝藻的生长没有受到明显的影响，而在高浓度下(10~100mg/L)，固氮蓝藻藻细胞在形态上出现受损症状，同时生长速率也受到明显的抑制。120h时，满江红鱼腥藻，水华鱼腥藻及固氮鱼腥藻的EC_(50)值分别为3.172， 3.654及3.377mg/L。

Roger and co-authors （1992） compiled data from more than 100 inoculation trials （ Table 5）, that indicate that on average, Azospirillum inocula have not been beneficial to rice crop yield.

Roger 和他的合作者（1992）整理了100多个接种试验的数据，认为固氮螺菌接种剂在总体上对水稻产量没有作用。

Furthermore, green manures have important effects on ecological environment, as well as energy and cost saving, carbon sequestration and emission reduction.

绿肥的主要作用包括提供养分、合理用地养地、提供饲草等传统意义上的作用，还有改善生态环境的重要作用，更有固氮吸碳和节能减耗作用。

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