在毛主席革命路线指引下,我县积极发展杉木用材林,造林质量逐年提高。但在丘陵地区造杉,普遍发生了蚁害。据调查,有的地区杉木被害率达60％以上。防治土白蚁的危害,已成为发展杉木基地建设中急待解决的问题。近两年来,我们进行了人工挖巢,化学防治,生物防治等多次试验,初步找到了用烟剂熏杀白蚁的好方法。其方法简便易行,省工省钱,易于推广。一、具体做法 1.掌握白蚁分群规律,发动群众普查移殖孔。移殖孔又叫分群孔、羽化孔、分飞孔。移殖孔直接通向主道(一般1米左右)。主道
Guided by Chairman Mao’s revolutionary line, our county actively developed the use of Chinese fir timber and the quality of its afforestation increased year by year. However, in the hilly areas fir, ants commonly occurred. According to the survey, in some areas the damage rate of Chinese fir is over 60%. Prevention and control of soil termites hazards, has become an urgent need to solve the problem of the construction of the fir base. In the past two years, we carried out artificial digging, chemical control, biological control and many other tests, initially found a good way to smother termites with tobacco smoke. The method is simple and easy, saving workers money, easy to promote. First, the specific approach 1. Grasping the rules of termites, mobilization of mass census colonies. Migration hole also known as sub-group hole, eclosion hole, sub-fenestration. Migration hole leads directly to the main road (usually about 1 meter). The main road
