nitrogen-fixation activity

基本解释

Reduced products were analyzed by GC to determine of nitrogen-fixation activity in biologically compound fertilizer.
采用气相色谱测定还原产物，以确定复合菌肥料的固氮活性。
Stable and high efficiency micro-plant interaction is essential to the optimal nitrogenase activity of root-associated nitrogen fixation bacteria.
联合固氮体系的建立是联合固氮菌发挥高效生物固氮活性的关键要素之一。
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.
试验研究了石灰性紫色土上花生施铁及不同铁浓度对花生根瘤菌共生固氮作用的影响。

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.
结果表明，2644为快生型根瘤菌，表现出相对较强的固氮酶活性，2656、2697为慢生型根瘤菌，也具有较强的固氮活性，修正了花生根瘤菌无快生型或快生型固氮活性低的传统说法。
