| 摘 要： | 硝酸钠在我国北方的黑土、白浆土等贫钾偏酸性土壤上施用,对甜菜有显著增产效果,与尿素比增产11.2％,在强石灰性土壤上施用也有一定的增产效果。故在钾素缺乏的土壤上施钠肥,可起到以钠代钾的作用。但施钠肥可使根中钠的含量增高,影响出糖率,也会增加土壤中钠的残留,因此应在低钠潮湿的土壤上合理使用。

| Abstract: | Sugarbeet could get yield increasing significantly when sodium nitrate supplied in the black soil and poor soil with low potash and acid soil of North China, yield increased 11.2% while compared with urea and the yield have certain increasing in the limy soil. So, it replaced the role of potash when the sodium supplied in the poor soil with potash. But the sodium content could be increased in the root with sodium supplied, reducing recoverable sugar and residual sodium also Increased in tne soil,thus it could be supplied rationally in low sodium and moist soil. |
