摘　　要：根据文献分析,明确植保无人机精准投放赤眼蜂卵球的具体技术指标,对提高水稻二化螟的生物防治效果具有重要的意义。通过采用三因素三水平正交试验对卵球投放高度、无人机飞行速度及卵球初始投放速度等投放精度相关指标进行分析,同时对卵球不同投放间隔处理的防治效果进行明确。结果表明:无人机飞行速度对于卵球漂移率的影响最大,其次是高度,最后是卵球初始速度。卵球投放高度10m、无人机飞行速度3m/s、卵球初始速度为3m/s的投放精确度最优组合,间隔8~16m投放1个卵球的防治效果相当。实现无人机精准投放赤眼蜂,要综合考虑无人机作业效果、赤眼蜂田间防治效果及作业成本等多种因素,从而更好地推动赤眼蜂在农业上的应用。以上结果可以为采用赤眼蜂卵球防治水稻二化螟提供一定的参考。The specific technical indicators for precise drone deployment of Trichogramma egg balls are crucial for improving the biological control effect on rice-stem borer.A three-factor and three-level orthogonal experiment was conducted to analyze the precision-related indicators of egg ball release height,drone flight speed,and initial release velocity.The results indicate that drone flight speed has the greatest impact on egg ball drift rate,followed by height and then initial release velocity.The optimal combination for release accuracy is a release height of 10 meters,a drone flight speed of 3 m/s,and an initial release velocity of 3 m/s.Intervals of 8~16 meters between egg ball releases result in similar prevention effects.To achieve precise drone deployment of Trichogramma,it is necessary to consider multiple factors such as drone operation effectiveness,field protection effect of Trichogramma,and operational cost,thereby better promoting the application of Trichogramma in agriculture.The above findings provide a reference for using Trichogramma egg balls for controlling rice-stem borer.
