摘    要:通过氮素水平对甜菜干物质积累与分配影响的研究表明:甜菜植株干物质积累量与施氮量呈显著正相关,r=0.979**。提高施氮量能增加甜菜各器官干物质积累量,但施氮量超过120kg/hm2时,再增施氮肥的处理则块根增长幅度减少。干物质分配随施氮水平的提高呈现出T/R比增加的规律,只有适宜施氮,使叶根生长协调,才会获得较高产量。

关 键 词:甜菜  氮素水平  干物质积累  分配

Abstract:There is a significant positive correlation between nitrogen amount and dry matter's accumulative amounts in sugarbeet plant, r=0.979**. increasing the nitrogen amounts, the dry matter accumulative amounts in all sugarbeet organs can be increased, but the sugarbeet root increase range is not few until nitrogen amount is 120 kg/ha. The T/R ratio of the dry matter distribution increase with the increase of nitrogen amounts in sugarbeet. Only applying a fit amount for roots and leaves growing well and a high yield can be harvested.
Keywords:Sugarbeet  Nitrogen amount  Dry matter accumulation  Distribution
