1981～1982年由民航沈阳管理局、辽宁省农业科学院植保所、民航总局科研所和台安县农业局共同协作,在台安县进行了飞机低容量喷洒乐果乳剂防治高粱蚜试验。为了达到低容量喷雾的要求,民航22大队改装了超低容量喷洒设备,使喷液量由0.1～0.3公斤增至1公斤左右,农药剂型改乐果油剂为乐果乳剂,每架次喷洒面积为800～1000亩。1981年试验作业8架次,面积为3365亩,示范作业62架次,面积为49600亩,1982年试验作业9架次,面积为4500亩,生产防治作业94架次,面积为74800亩。两年来总共飞行作业173架次,防治面积达132265亩。在防治效果不低于常规喷雾(95%以上)的情况下,提
From 1981 to 1982, Shenyang Civil Aviation Administration, Plant Protection Institute of Liaoning Academy of Agricultural Sciences, CAAC Scientific Research Institute and Taian County Bureau of Agriculture worked together to carry out low-capacity aircraft spraying dimethoate emulsion control test on aphids in Taian County. In order to meet the requirements of low-volume spraying, the Civil Aviation 22 Battalion remodeled an ultra-low volume spraying equipment to increase the liquid spray volume from 0.1 to 0.3 kg to about 1 kg. Pesticide-based pomegranate oil is a dimethoate emulsion. The spray area per rack 800 ~ 1000 acres. In 1981, there were 8 sorties of vehicles with an area of 3,365 mu and 62 demonstration projects with an area of 49,600 mu. In 1982, there were 9 test operations and an area of 4,500 mu. There were 94 prevention and control operations with an area of 74,400 mu. In the past two years, a total of 173 sorties were flown and the control area reached 132,265 mu. In the control effect is not less than the conventional spray (95% or more), mention
