为了研究物理防治在综合防治措施中的效能,1978年我们与本院农训班协作,在8—11月间观察了1000支光金属卤化物灯(以下简称卤灯) 的诱虫效果,并与20支光黑光灯(以下简称黑灯) 和200支光电灯(以下简称白灯),进行诱虫比较.现将观察结果,报导如下: 一、灯具安装和试验经过采用江苏师范学院研究成功的金属卤化物灯中效果较高的镓钴灯.灯管固定在钢筋三角架上,架上设防雨帽、集虫漏斗及集虫箱.集虫箱分层装15毫米、8毫米、3毫米三种不同规格的铁丝筛.光源照顾不同高度的农林作物,离地面3.5米,离灯2米设百叶箱一只,安放触发器和限流器等附件,灯北以3米多高的铁路路基为屏障,其他三方面是水稻田和菜地.
In order to study the effectiveness of physical control in comprehensive prevention and control measures, in 1978 we cooperated with our agricultural training course to observe the trapping effects of 1000 photo-metal halide lamps (hereinafter referred to as halogen lamps) from August to November And 20 light black light (hereinafter referred to as black light) and 200 light (hereinafter referred to as white light), compared with the attractant now observation results are reported as follows: First, the installation and testing of lamps After the success of the Jiangsu Institute of Technology Of the metal halide lamp higher gallium cobalt lamp. The lamp is fixed on the steel tripod, the shelves set rain hat, set funnel funnel and set of worm shelves. Set worm shelves layered 15 mm, 8 mm, 3 Mm three different specifications of wire mesh sieve.Light source to take care of different levels of agriculture and forestry crops, 3.5 meters from the ground, 2 meters from the lamp set a shutter box, place the trigger and restrictor and other accessories, the lamp north to 3 meters high Railway subgrade as a barrier, the other three areas are paddy fields and vegetable fields.
