摘要: 为筛选出适合植保无人机喷施球孢白僵菌制剂防治水稻二化螟的最佳飞行参数,本文利用大疆公司T20型植保无人机喷施球孢白僵菌制剂,探索不同飞行参数(飞行高度、飞行速度)对球孢白僵菌制剂沉积量(单位面积内球孢白僵菌孢子沉积个数)的影响,对筛选出的最优飞行参数进行田间试验并调查防治效果。飞行高度和飞行速度两个因素分别对单位面积内球孢白僵菌制剂沉积量存在显著影响,其中飞行高度因素对其影响更为显著,但两者之间的交互作用对其影响不显著;当飞行高度为1.5 m、飞行速度为3.0 m/s~5.0 m/s时,球孢白僵菌制剂沉积量高于其他处理;当飞行高度为1.5 m、飞行速度为5.0 m/s时,田间防治水稻二化螟的防治效果可达到75.34%。通过本研究,确定了植保无人机喷施球孢白僵菌制剂防治水稻二化螟的最佳飞行参数为飞行高度1.5 m,飞行速度5.0 m/s,水稻二化螟的田间防治效果可达75.34%以上。由此可见,利用植保无人机喷施球孢白僵菌制剂防治水稻二化螟的防治效果明显,具有大面积推广应用的价值。

Abstract: The optimal flight parameters of plant protection UAV suitable for Beauveria bassiana formulation spraying to control rice stem borer were established with the Dajiang T20 plant protection UAV through measuring the effects of different flight parameters (height and speed) on the deposition of B. bassiana formulation (the number of fungal conidia deposited per unit area). The optimal flight parameters were tested in the field experiments for their effects on pest control. The results showed that the deposition of B. bassiana formulation was significant influenced by both the flight height and speed of UAV, with the flight height being more important and no significant interaction of the two factors. When the flight height was 1.5 m and the flight speed was 3.0 m/s-5.0 m/s, the deposition of B. bassiana formulation was higher than those of the other flight treatments; when the flight height was 1.5 m and the flight speed was 5.0 m/s, the control efficiency against rice stem borer was 75.34% in field experiment. In conclusions, the optimal flight parameters for the plant protection UAV to spray B. bassiana formulation for rice stem borer control are flight height of 1.5 m and flight speed of 5.0 m/s, which can achieve a pest control efficiency of more than 75%. Herein it is of significance for large-scale application plant protection UAV to spray B. bassiana formulation for rice stem borer control in field.
