| 摘 要： | :研究了在不同配比的NO3- -N与NH4 +-N下大豆根瘤的生长及根瘤固氮酶活性和叶片全氮含量的变化。结果表明 :7种配比的NO3- -N与NH4 +-N均降低根瘤鲜重 ,抑制根瘤固氮酶活性 ,但提高叶片全氮含量。叶片全氮含量与根瘤鲜重、根瘤固氮酶活性之间呈显著负相关

Study on the Relations between Commensally Nitrogen Fixation and the Total Nitrogen Content of Leaves in Soybean |

| Abstract: | The nodule′s growth,nodule nitrogenase activities and the total nitrogen content of leaves were researched in soybean under different proportion of NO 3 --N and NH 4 +-N fertilizer.The results indicated that seven proportion of NO 3 --N and NH 4 +-N reduced fresh nodule weight and inhibited activity of nodule nitrogenase,but increased the total nitrogen content of leaves.The negative correlation between the total nitrogen content of leaves and fresh nodule weight,nodule nitrogenase activity were significant respectively. |
