摘要
为有效灭除草地害草轮叶马先蒿,采用2,4-D丁酯在巴音布鲁克高寒草地进行了不同时期不同剂量化学防除试验。结果表明,防除轮叶马先蒿的最佳时期为盛花期;最佳药品用量是0.066 mL/m2;喷施2,4-D丁酯后,草地植被生态环境得到明显改善,轮叶马先蒿被部分或完全灭除,优良牧草垂穗披碱草在草地群落中占据优势地位,同时杂类草新疆假龙胆受到一定的抑制,草地质量明显提高。
The herbicide 2,4-D butyl ester was used to control Pedicularis verticilata efficiently. The best time for control of P. verticilata was florescence and the concentration was 0. 066 mL/m^2. The grassland vegetation ecological environment was obviously improved after spraying 2,4-D butyl ester herbicide. P. verticilata was entirely or partially controlled and the high quality forage Elymus multicaulis became dominant. The harmful grassland weed Gentianella turkestanorum was inhibited to some degree. In summary, grassland quality was efficiently improved.
