近年来,苏联及其他国家,采用烟雾剂毒杀林内的吸血昆虫及森林害虫。1956年我国东北林区开始利用(26)111-A和(6)111-A2种烟雾剂,毒杀林区吸血昆虫。同年10月间,林业部用(26)111-A烟雾剂,进行马尾松毛虫毒杀试验。1957年继续在中南、华东、东北、西南等地,组织分点进行技术上的传授和推广。兹将几次放烟试验的体会,综合分述如下,以供实地使用烟剂时的参考。
In recent years, the Soviet Union and other countries use smog to kill blood-sucking insects and forest pests in the forest. In 1956, Northeast China’s forest areas started to use (26) 111-A and (6) 111-A2 aerosols to kill the blood-sucking insects in the forest areas. In the same year in October, the Ministry of Forestry used (26) 111-A aerosol to test the toxicity of Masson pine caterpillars. In 1957 continue to be in South Central, East China, Northeast China, Southwest and other places, organize points for technical transfer and promotion. We hereby give a few examples of the experience with the smoke test, which is summarized as follows for reference when using tobacco smoke in the field.
