摘要: 棘豆的大面积滋生繁衍是草地退化的一个重要标志,对草原畜牧业发展构成了重大危害。文章通过自配制除草剂——"灭棘豆"对棘豆杀灭效果的试验研究得出结论:"灭棘豆"的最佳推广用药量为1 350~1 650 mL·hm-2,喷药最佳时间是在棘豆盛花期。它灭除棘豆死亡率达92%以上,对草原可食牧草和环境无害。"灭棘豆"可以作为一种经济有效且适宜大面积灭除棘豆的除草剂而大面积推广。

Abstract: The prosperous development of Oxytropis ochrocephala is a serious symbol of grassland degradation,which greatly harms the animal husbandry.A kind of herbicide "Miejidou" confected by the author of this thesis was experimentally used to destroy Oxytropis ochrocephala.The effective quota of "Miejidou" is 1 350~1 650 mL·hm-2,and the best spraying time is at the bud period.In such case the death rate of Oxytropis ochrocephala surpasses 92%,and it does not contaminate the edible herbs and pollute environment as well.This method is suitable for extending in large area.

Key words: Oxytropis ochrocephala, grassland degradation, herbicide, ecological rehabilitation
