摘要
氮素水平影响玉米的产量和生理特性,合理施用氮素与获得较高产量和改善生理性状有密切关系。本研究从玉米植株形态、干物质积累、非结构碳水化合物、叶片光合特性、品质和产量等方面阐述氮素水平对玉米产量生理的影响。
Previous studies showed that great change in yield and physiological traits,desired traits and high yield could be obtained through controlling level of N.This paper summarized the physiological changes,including growth of plant,dry matter accumulation,photosynthetic efficiency,non-structural carbohydrates,quality of seeds and yield could be caused by level of N.
