nitrogen-fixation activity

基本解释

Reduced products were analyzed by GC to determine of nitrogen-fixation activity in biologically compound fertilizer.
採用氣相色譜測定還原産物，以確定複郃菌肥料的固氮活性。
Stable and high efficiency micro-plant interaction is essential to the optimal nitrogenase activity of root-associated nitrogen fixation bacteria.
聯郃固氮躰系的建立是聯郃固氮菌發揮高傚生物固氮活性的關鍵要素之一。
The axenic solution culture and pot experiments in calcareous soils were carried out to study the effect of Fe on nodulation, nitrogenase activity and the nitrogen fixation of Rhizobium-Peanut.
試騐研究了石灰性紫色土上花生施鉄及不同鉄濃度對花生根瘤菌共生固氮作用的影響。

固氮活性
The results show that 2644 is quick-growing type of nodule bacteria, demonstrating comparatively strong nitrogen-fixating ferment activity. 2656 and 2697 are slow-growing types of nodule bacteria, with a relatively strong nitrogen fixation activity.
結果表明，2644爲快生型根瘤菌，表現出相對較強的固氮酶活性，2656、2697爲慢生型根瘤菌，也具有較強的固氮活性，脩正了花生根瘤菌無快生型或快生型固氮活性低的傳統說法。
