林地杂草丛生,不仅会与幼林争光,争水、争肥,还会促进林内病虫滋生,严重影响林木生长。我国南方大部分林地地形复杂,气候多变,用人工方式除草要消耗巨大的人力、财力,而且速度缓慢。但使用化学药剂除草,既能尽快解决草害问题,又能降低除草成本与劳动强度,提高经济效益。草甘膦、森草净是高效、低毒、广谱性芽后除草剂,又是内吸、传导性除草剂,能防除林地内的一年生禾本科、莎草科类杂草,阔叶草和林地灌丛等。 Woods overgrown, not only glory with young, competing for water, fertilization, but also to promote the breeding of pests in the forest, seriously affecting the growth of trees. Most of China’s southern woodland topography complex, changing climate, artificial way to weeding to consume huge human and financial resources, but also slow. However, the use of chemical weed control can not only solve the grass-pest problem as soon as possible, but also reduce the cost and labor intensity of weeding and increase economic benefits. Glyphosate, Sencao net is efficient, low toxicity, broad-spectrum post-emergence herbicide, but also suction, conductive herbicides, can control woodland annual gramineous, Cyperaceae weeds, broadleaf grass And woodland shrubs and so on.
