摘要
本文开展了T40植保无人机喷洒绿木霉可湿性粉剂+多粘类芽孢杆菌可湿性粉剂混合药剂防治龙牙楤木叶斑病试验。结果表明:在两块试验地上,植保无人机飞行高度为6~8 m,飞行速度7 m/s,喷雾宽度8~10 m,喷雾量10~13 L/min,雾滴喷洒颗粒均匀。喷洒过后处理组病株率相较于空白组分别低了17.78%、18.89%,相对防治效果分别为76.79%、81.39%。无人机施药具有成本低、方便易操作、效率高等优点,推荐在实践中使用无人机喷施混合药剂防治龙牙楤木叶斑病。
In this paper,T40 plant protection UAV sprayed with Trichoderma viridis wettable powder+Bacillus polymyxoides wettable powder to prevent leaf spot disease of Ascochyta araliae.The results show that:In the two test sites,The flying height of the plant protection UAV is 6-8 meters,the flying speed is 7 meters/second,the spray width is 8-10 meters,the spray volume is 10-13 liters/minute,and the droplets are sprayed evenly.compared with the blank group,the disease rate in the sprayed group was 17.78%and 18.89%lower,and the relative control effect was 76.79%and 81.39%,respectively.Uav application has the advantages of low cost,convenient operation and high efficiency.It is recommended to use UAV spraying mixed agents in practice to prevent leaf spot of Ascochyta araliae.
