采用化学除草开设与维护森林防火线,是一项因地制宜的技术。根据国内研究报导,目前喷施以草甘膦为主剂的化学除草施工,一般采用高容量喷雾技术,每亩用水在40公斤以上,这对山峦起伏、坡度大、取水远的桂北山区开设森林防火线来说(特别是山脊地段),是限制高容量喷雾施工的一项主要因素。而采用工农—16型手动喷雾器与1.0毫米口径的喷头片配套,进行中容量喷雾,减少用水量,是解决取水难的关键问题。
The use of chemical weeding to set up and maintain forest fire prevention lines is a well-established technology. According to the domestic research reports, at present, spraying chemical glyphosate-based chemical weeding construction generally uses high-capacity spray technology, with a water consumption of more than 40 kg per mu. For the forest fire line (especially ridge areas), it is a major factor limiting the construction of high-volume spray. The use of workers and peasants -16 type manual sprayer and 1.0 mm nozzle nozzle supporting the amount of spray in the capacity to reduce water consumption, water is difficult to solve the key issues.
