北京市植保站注意解决病虫测报技术人员在田间观测难度大、劳动强度大等问题,下功夫试验研究多种测报调查工具。近两年,在八十年代初以来的研究工作基础上,进一步试验示范粘虫自动捕蛾器(见本期封面,顺义县麦田设置的一组自动捕蛾器),经不断改进,取得令人满意的效果。粘虫自动捕蛾器内置杨枝把,外罩玻璃钢套,可定时自动关闭并熏蒸,测报技术人员只需在方便时将自动捕蛾器开启并取回粘虫蛾即可,到翌日清晨已定时刻捕蛾器又自动下落关闭。由于其省时、
Beijing Plant Protection Station to address the pest forecasting technical staff in the field of observation is difficult, labor-intensive and other issues, make efforts to test a variety of survey reporting tools. In the past two years, on the basis of the research work since the early 1980s, further experiments were carried out to test the demonstration of the instability of the armyworms (the cover of this issue, a group of automatic catching moths set up in the wheat field of Shunyi County) Satisfaction of people. Mythimna autotrophic moth built-in Yang Zhi, cover glass steel sleeve, can be automatically shut down and fumigation regularly, the reporter only at the convenience of the automatic catching moth open and retrieve the armyworm can, to the next morning has been set Moth catches the moment and automatically fall off. Because of its time saving,
