在华北落叶松幼林地采用草甘膦、威尔柏化学除草剂,以不同浓度进行化学除草试验,并观察了草本、灌木植物喷施除草剂后的外观反应。结果表明:用草甘膦、威尔柏对华北落叶松幼林地进行除草,不仅除草效果好(75.9%～96.8%),而且成本低(47.2%～78.9%)。
Glyphosate and Wilbur’s chemical herbicide were used in young Larix principis-rupprechtii and chemical herbicides were tested in different concentrations. The appearance reaction of herbaceous and shrub plants was observed after they were sprayed with herbicide. The results showed that weeding grass with Larix principis-rupprechtii with glyphosate and Wilber’s could not only weed the soil well (75.9% -96.8%) but also low cost (47.2% -78.9%).
