摘要
新研制的ＨＵ２－ＨＷ１型超低容量喷洒设备及ＮＴ１００ＧＰＳ导航系统与海燕６５０Ｂ飞机配套技术，首次应用于广西武鸣林区防治森林病虫害。２．５％ＥＣ溴氰菊酯用０＃柴油稀释为油剂，施药量（乳油）为３０、４５ｍＬｈｍ－２；水剂则为６０ｍＬｈｍ－２。航空超低容量喷洒防治松毛虫平均死亡率依次为９６．４％、９８．３％和９７．６％；松茸毒蛾为９３．６％（水剂）。１０００亿孢子ｇ－１球孢白僵菌，施孢子量为１２０ｇｈｍ－２（其配比：孢子水吐温－８０盐＝５１０００．５０．５）。搅拌均匀，再加３．０Ｌ水稀释，航空超低容量喷洒防治马尾松毛虫和松茸毒蛾，平均死亡率依次为６７．７％和５０．３％。
When being equipped with the petrel 650B motor glider,the HU2 HW1 spraying equipment of ultra low volume (ULV) and the NT100 Global Positioning System (GPS) were first applied in the forest region in Wuming County,Guangxi,for control of forest pest and disease there. When 2.5% EC deltamethrin was diluted with 0 # Diesel oil and sprayed at 30 and 40 mL·hm -2 during an aerial spraying,the average mortality rates of pine caterpillar were 96.4% and 98.3% respectively. When 2.5% EC deltamethrin was diluted with water and sprayed at 60 mL·hm -2 in a similar spraying,the average mortality rates of pine caterpillar and Dasychira axutha were 97.6% and 93.6% respectively. 100 billion spores·g -1 Beauveria bassiana was sprayed at 120 g·hm -2 being mixed at the formula of 5 spores∶100 water∶0.5 Tuwen 80∶0.5 salt,plus 3 liter water for further dilution,the death rates of pine caterpillar and D. axutha were 67.7% and 50.3% respectively.
