为掌握克胜·蜻蜓-1 6无人机的多种技术参数及其病虫防治技术,研究了克胜·蜻蜓-1 6无人机超低量喷雾在小麦田的雾滴沉积分布及对赤霉病的防治效果。结果表明,克胜·蜻蜓-1 6无人机飞行高度距作物上部2m,前进速度4 m/s,每667 m~2喷药液量1L,每667 m~2添加克胜专用喷洒助剂10 mL,药液在小麦上部、中部、下部叶片的沉积量分别为0.51、0.40、0.32μg/c m~2,在小麦整个植株上的沉积率达48.8%,均比未添加克胜专用喷洒助剂的药液沉降率要高。在小麦扬花初期,采用无人机喷药,每667 m~2用己足50 mL+又胜20 mL+克胜专用喷洒助剂10 mL喷雾,5 d后再用己足+克胜专用喷洒助剂进行第2次喷雾,对小麦赤霉病的防效达78.4%,优于其他采用无人机喷药、未添加助剂的处理,且与人工电动喷雾器处理间防效差异不显著。采用无人机喷洒己足、又胜防治小麦赤霉病,未发现小麦生长异常。
In order to grasp a variety of technical parameters of kunsheng dragonfly -1 6 UAV and its pest control technology, the study of the kudzu dragonfly -1 6 UAV spray in the wheat field droplet distribution and Fusarium head blight control effect. The results showed that the Kesheng dragonfly -1 6 flight altitude was 2 m above the crop and the speed of advance was 4 m / s. The spray liquid per 667 m ~ 2 was 1L, and every 667 m ~ 2, 10 mL. The deposition rate of the liquid in the upper, middle and lower leaves of wheat was 0.51,0.40,0.32μg / cm ~ 2, respectively. The deposition rate of wheat on the whole plant was 48.8% Agent liquid sedimentation rate is higher. In the early flowering wheat, the use of unmanned aerial vehicles, every 667 m ~ 2 with 50 mL + has won 20 mL + Kesheng special spray additive 10 mL spray, 5 d and then have enough + grams of special spray additives The second spray, the control effect of wheat scab over 78.4%, better than other UAV spraying, without adding additives treatment, and artificial electric sprayer control effect was not significantly different. Drones sprayed by UAVs was enough to win the control of wheat scab. No abnormal growth of wheat was found.
