| 摘 要： | 研究了脲甲醛缓释氮肥与尿素不同混合比例施用对油菜(Brassica campestris L.)产量和农艺性状的影响。结果表明,脲甲醛缓释氮肥与尿素以1∶2的比例混合施用时效果最佳,且应注意与磷、钾肥以及微量元素配合施用。另外,如果只施用尿素作为氮肥时,就要采用分段施用的管理措施。

Study on Appropriate Proportion of Slow Release Nitrogen Fertilizer in Rape |
| |
| Abstract: | The effects of different mixing ratio between slow release nitrogen fertilizer of urea formaldehyde and urea on the yield and agronomic traits of rape were studied. The results indicated that, the best mixing ratio was 1 to 2 for slow release nitrogen fertilizer of urea formaldehyde and urea, and phosphorus, potash and trace elements should be combined application with. In addition, urea should be applied by stages when only urea was used as nitrogen fertilizer. |
