摘要
论述了不同形态氮素对甜菜硝酸还原酶活性、谷氨酰胺合成酶活性及蔗糖合成酶活性的影响,并在影响生理生化过程的基础上,对氮素形态和甜菜生长发育及产质量的相关性进行了分析,提出了不同形态氮素配合施用是提高甜菜保护酶系统活性及其抗逆性的有效途径。
The effect of different nitrogen forms on nitratase, glutamine synthetase and sucrose synthetase in sugarbeet was summarized, and the correlation between the nitrogen forms and growth, development, yield and quality of sugarbeet was analyzed under physiological and biochemical influences. In addition, the application of different nitrogen forms in proper proportion was suggested for increasing the activity of protective enzyme system and resistance of sugarbeet.
