1.
This article laid great emphasis on the method and procedure of in situ determination of pelagic nitrogen fixation rate in aquaculture ponds, and some improvements, such as the use of syringe as incubator and the adiustment of the amount of yielded gas volume, were proposed.
侧重应用乙炔还原法进行养殖池水层生物固氮作用原位测定的具体操作步骤 ,并提出了应用医用注射器作为原位培养容器和对培养后生成的气体体积进行了校正的改进措施。
2.
The optimal pO2 of nitrogen fixation,respiration rate of stem nodule bacteroids, nodule leghemoglobin and cytosol soluble protein were reduced by water deprivation.
测定不同ｐＯ２下离体茎瘤固氮活性以ｐＯ２为６０％最高；当把茎瘤切碎后，茎瘤皮层的扩散屏障作用降低或失去，最适ｐＯ２降至４０％，说明Ｏ２是茎瘤固氮作用的限制因子。
3) fixation of nitrogen
氮素固定作用
4) symbiotic nitrogen fixation
共生固氮作用
5) asymbiotic nitrogen fixation
非共生固氮作用
6) groundnut nitrogen fixation
