在上海民航局和杭州民航局的支持协同下,我场于1967年首次在茶树上进行大面积飞机防治试验,获得成功。防治面积为7052亩次,主要防治对象为茶尺蠖、茶二叉蚜和茶橙瘿螨。药剂及浓度为:敌敌畏:水=1.20:100;敌百虫:乐果:水=0.90:0.13:100;敌百虫:乐果:水=0.90:0.20:100;乐果:水=0.20:100。试验结果表明,飞机喷治对茶尺蠖和茶二叉蚜的效果较好,一般一、二令茶尺蠖喷药后
With the support of Shanghai Civil Aviation Authority and Civil Aviation Administration of Hangzhou, I successfully conducted a large-scale plane control experiment on tea plants in 1967 for the first time. Control area of 7052 mu times, the main control object for the tea scallops, tea aphids and tea orange spider mites. Drugs and concentrations: dichlorvos: water = 1.20: 100; trichlorfon: dimethoate: water = 0.90: 0.13: 100; trichlorfon: dimethoate: water = 0.90: 0.20: 100; dimethoate: water = 0.20: 100. Test results show that the jet spray on the tea scallop and tea aphides better effect, usually one or two orders after the 尺 蠖 spraying
