| 摘 要： | 试验结果表明,随着施氮量的增加,甜菜根产量的增加趋势是平缓的,当施氮量达到150kg/hm2,根产量不再增加;随施氮量的增加,茎叶产量明显增加,茎叶重与根重比也增大,同时糖浸出液中钾、钠等不纯性物质的含量增加,导致含糖率下降,产糖量降低。

| Abstract: | The experimental results showed that the root yield of sugar beet were slowly increased while increasing the nitrogen amounts,the leaves and tops yield and the T/R ratio were obviously increased with increasing the nitrogen amounts;the sugar content and sugar yield were decreased while potassium and sodium from sugar beet soak increased with increasing the nitrogen amounts. |
