杂草是顽强的生存竞争者。尤其是白茅(尖刀草)、铁线草(狗牙根)、蒿类、紫茎泽兰等恶性多年生杂草已普遍对分布于山区缓坡、沟谷和山腹等地带的茶桑果园及其它经济林木园构成严重为害,甚至已使有的园地走向荒废而绝产。为适应现代生态农业的发展和合理地利用山地资源,迫切需要应用优良的化学除草剂。草甘膦(Glyphasate)是一种高效、安全的新型除草剂。于1985年在大理州局部地区进行了小范围使用,收到了一定的效果。为进一步寻求其因地制宜的应用技术,提高
Weeds are tough survival competitors. In particular, weeping perennial weeds such as Imperata cylindrica (Ctenopharyngodon idellus), Clematis (Bermudagrass), Artemisia species, and Eupatorium adenophorum have generally been widely distributed in tea mulberry orchards and other economic forest gardens distributed in areas of gentle slopes, valleys, Constitute a serious harm, and even some of the park has been abandoned to abortion. In order to adapt to the development of modern ecological agriculture and make rational use of mountain resources, it is urgent to apply good chemical herbicides. Glyphasate is a highly effective and safe new herbicide. In 1985, a small area of Dali Prefecture was used in a small area and received some results. In order to further seek its application of technology to local conditions, improve
