| 摘 要： | 通过试验示范探索拿敌稳对水稻穗期氮肥使用量的调控,综合分析结果:水稻施用拿敌稳免去穗肥(氮素)对水稻产量性状影响不大,而且防治稻瘟病效果较好,水稻抗倒伏能力强。建议在水稻始穗期和齐穗期各喷一次药,每次用药量为15 g/667 m^2,这样既减少化肥使用量,同时又达到了防治稻瘟病效果。

| Abstract: | This study was conducted to explore the effect of Nadiwen on the amount of nitrogen fertilizer used in rice spike stage.The comprehensive analysis results showed that the application of Nadiwen without panicle fertilizer(nitrogen)had little effect on rice yield and characters,and the effect of rice blast control was good,and the lodging-resistance capability was strong.It is suggested to spray it once at the beginning heading stage and full heading stage of rice,and the dosage is 15 g/667 m^2 each time,which can not only reduce the amount of chemical fertilizer,but also achieve the effect of rice blast control. |
