摘要
论述海燕 6 5 0 B轻型飞机防治森林害虫的作业技术 ,系统探讨诸因素与防治效果和作业效率的关系。结果表明 ,海燕 6 5 0 B轻型飞机在风速小于 3m/ s,飞行高度在 10 - 2 5 m间 ,作业速度 110 km / h时 ,利用超低量喷洒技术 ,运用风动式雾化器喷洒白僵菌生物制剂与化学农药的混合剂防治森林害虫 ,防治效果好 ,经济效益高。
The operating technique on controlling forest pests by Haiyan 650B light airplane was summarized, and the relationship of various factor with the effect and efficiency of control was discussed systematically. The result indicated that when the wind velocity is less than 3 meter per second, the Haiyan 650B light airplane flied 10 to 25 meter in high with the speed of 110 kilometer per hour, spraying the mixture of biological preparation (such as Beauveria bassiana ) and pesticide to control forest pests can get good effect and high efficiency, by use of hyper few quantity spray.
