摘 要：【目的】随着现代农业技术的不断发展，机械化程度不断加快，亟需探究不同植保机械对水稻虫害的防治效果。【方法】课题组以背负式电动喷雾器、自走式喷雾机、植保无人机为主要试验机械，以水稻稻纵卷叶螟和稻飞虱为试验对象，分别设置4 个处理：背负式电动喷雾器施药处理、自走式喷雾机施药处理、植保无人机施药处理和对照组（CK）。【结果】从稻纵卷叶螟防治效果看，与对照组相比，自走式喷雾机防治效果最好，在用药后6天、10天，处理后虫量分别为0.6万头/亩和0.47万头/亩， 防效分别达到94.46%和95.66%。从稻飞虱防治效果看，与对照组相比，背负式电动喷雾器防治效果最好，在用药后6天、10 天，处理后虫量分别为8.7万头/亩和7.5万头/亩，防效分别达到67.54%和72.01%。【结论】3种植保机械处理均能防治这2种水稻虫害，虽然背负式电动喷雾器和自走式喷雾机相对来说效果更好，但采用植保无人机处理能够进一步降低水稻虫害防治的时间和成本。

Abstract: [Objective] With the continuous development of modern agricultural technology and the acceleration of mechanization, it is urgent to explore the control effects of different plant protection machinery on rice pests. [Method] The research group took backpack electric spray, self-propelled spray and plant protection UAV as the main test machines, and rice leaf roller and rice planthopper as the test objects. Four treatments were set up respectively: backpack electric spray application treatment, selfpropelled spray application treatment, plant protection UAV application treatment and control group (CK). [Result] From the perspective of the control effect of the rice leaf roller, compared with the control group, the self-propelled spray had the best control effect. After 6 days and 10 days of treatment, the amount of insects after treatment was 6 000 heads/mu and 4 700 heads/mu, respectively, and the control effect reached 94.46% and 95.66%, respectively. From the perspective of the control effect of rice planthopper, compared with the control group, the backpack electric spray had the best control effect. After 6 days and 10 days of treatment, the amount of insects after treatment was 87 000 heads/mu and 75 000 heads/mu, respectively, and the control effect reached 67.54% and 72.01%, respectively. [Conclusion] 3 Mechanical treatment of plant protection can prevent and control these two kinds of rice pests. Although backpack electric spray and self-propelled spray are relatively effective, using plant protection UAV treatment can further reduce the time and cost of rice pest control.
