| 摘 要： | 对等行、宽幅2种播种方式及单层喷药、双层喷药、无人机喷药3种喷雾方式对冬小麦成株期叶锈病的控害及增产效果进行研究。结果显示:在相同喷药方式条件下,与常规等行播种相比,宽幅播种对叶锈病防效显著(病株率降低70%),增产效果明显(22.77%);常规单层喷雾和无人机均可显著降低叶锈病病株率70%左右,双层喷雾效果不显著,但是产量均较对照明显增加15%以上。

| Abstract: | 2 kinds of planting methods and 3 spraying methods were applied to control and increase the yield of winter wheat seedling leaf rust. The results showed that under the same spraying mode, compared with the conventional equidistant row sowing,broad width sowing had a significant effect on leaf rust(diseased plant rate decreased by70%), and the effect of increasing yield was obvious(22.77%). Conventional single layer spray and UAV significantly reduced the incidence of leaf rust disease by 70%, and the effect of double layer spray was not significant, but the yield increased by more than 15% compared with the control. |
