摘要:

为研究植保无人机不同作业参数对稻飞虱防治效果的影响,在浙江省金华市早稻孕穗期和晚稻分蘖期分别开展田间试验,分析用水量、作业高度和飞行速度对防治效果的影响。结果表明:用水量是影响无人机防治效果的首要因素,孕穗期每667 m2用水量4 L较2 L对稻飞虱的防治效果提升19.95~25.59百分点,分蘖期每667 m2用水量3 L即可实现最佳防治效果。作业高度对防治效果的影响因生育期而异,孕穗期作业高度2~3 m防治效果较为稳定;分蘖期作业高度从2 m升至4 m,防治效果差异较大。飞行速度4 m·s-1与5 m·s-1之间差异不明显。在适宜作业参数下,无人机施药防治效果与背负式电动喷雾器相当,且对水稻生长无不良影响。综上,水稻分蘖期植保无人机推荐作业参数为高度2 m、每667 m2用水量3 L、速度4 m·s-1;孕穗期推荐作业高度2~3 m、每667 m2用水量4 L、速度4~5 m·s-1。

Abstract:

To investigate the effects of different operational parameters of plant protection unmanned aerial vehicle(UAV)on the control efficacy against rice planthoppers,field trials were conducted during the booting stage of early-season rice and the tillering stage of late-season rice in Jinhua City,Zhejiang Province,China. The effects of spray volume,operating height,and flight speed on control efficacy were analyzed. The results showed that spray volume was the primary factor affecting the control efficacy of UAV. At the booting stage,increasing spray volume from 2 L to 4 L per 667 m2 improved the control efficacy by 19.95-25.59 percentage points;at the tillering stage,a spray volume of 3 L per 667 m2 was sufficient to achieve the optimal control efficacy. The effect of operating height on control efficacy varied with growth stage:at the booting stage,operating heights of 2-3 m provided relatively stable control efficacy;at the tillering stage,increasing operating height from 2 m to 4 m resulted in considerable differences in control efficacy. Flight speeds of 4 m·s-1 and 5 m·s-1 showed no significant difference in control efficacy. Under appropriate operational parameters,UAV application achieved control efficacy comparable to that of knapsack electric sprayer,with no adverse effects on rice growth. In conclusion,the recommended operational parameters for UAV application at the tillering stage of rice are operating height of 2 m,spray volume of 3 L per 667 m2,and flight speed of 4 m·s-1;at the booting stage,the recommended parameters are operating height of 2-3 m,spray volume of 4 L per 667 m2,and flight speed of 4-5 m·s-1.
