我省大面积利用黑光灯诱杀农业害虫的试验,于去年八月份才开始,今年继续与中央第四机械工业部协作,在十三个县、市的十六个单位中进行。试验作物有水稻、甘蔗、棉花和桑树等四种,试验面积达18550亩,安装了20瓦的黑光灯351支。一般均在三月下旬开始亮灯,至6月底止,共诱杀了4822.5市斤害虫,其中单支黑光灯一夜最多的能诱杀3.4市斤,害虫种类近二百种。因此,在各种试验作物上都显示了一定的防治效果。现将试验结果整理如下,以供生产上参考应用。一、黑光灯对水稻害虫的诱集作用及田间效果
The pilot project of trapping and killing agricultural pests in large areas using black light in our province did not start until August last year. This year, it continued to cooperate with the Fourth Machinery Industry Department of the Central Government in 16 units in 13 counties and cities. The test crops include rice, sugar cane, cotton and mulberry and other four kinds of test area of 18,550 acres, the installation of 20 watts of black light 351. Generally began to light up in late March until the end of June, trapping a total of 4822.5 kilograms of pests, of which a single black light up to 3.4 kilograms per kilogram overnight, nearly 200 species of pests. Therefore, in a variety of experimental crops have shown some control effect. The test results are summarized below, for the production of reference applications. First, the black light on rice pests trap effect and field effects
