1965年上海农业药械厂试制成功一种手提烟雾机(见图),利用脉冲式喷气发动机排出的高温气体之热能和高速气流之动能,使液态烟剂受热与冲击挥发成烟雾。烟雾的颗粒小,沉降缓慢,因此飘浮远,便于进行大面积纵深喷烟。在南方森林植物检疫站的组织下,我们于1965年在江西弋阳用该机进行了防治马尾松毛虫的生产试验。试验证明,该机具性能良好,机体轻巧灵便,适于树高、林密、坡陡的山区使用。
In 1965, Shanghai Agricultural Yakeli successfully piloted a hand-held smoke machine (see photo), which made use of the thermal energy of the hot gas and the kinetic energy of the high-speed air discharged from the pulsed jet engine to volatilize the liquid smoke and smoke into the smoke. Small particles of smoke, slow settling, so floating far, easy to carry out a large area of deep smoke. In the southern forest plant quarantine station under the organization, we in 1965 in Yiyang, Jiangxi with the aircraft for the production of pine caterpillar control test. Test proved that the good performance of the machine, the body lightweight and flexible, suitable for tree height, forest dense, steep slopes of the mountain use.
