摘要
硝酸还原酶对氮素非常敏感,其酶活力与施氮量呈显著正相关,且能较好地反映蔗株体内的氮素代谢。钾对该酶亦有促进作用。因此,把硝酸还原酶活力作为诊断蔗株氮素营养水平的指标是有可能的。
The nitrate reductase is very sensitive to nitrogen treatment, and has positive correlation with fertilizer quantity. This enzyme can re- flect better the metabolism of nitrogen in vivo, and be promoted by po- tassium too. Therefore, it is possible to use the activity of nitrate redu- ctase as a parameter of diagnosing the nitrogen nutrition in sugarcane.
