摘要
禾本科醉马草是天然草原上分布广,对牲畜为害最大的主要毒草之一。本试验用除草剂——草甘膦和耕作两种防除方法,结果以10%草甘膦11.25kg/ha^+皂粉3kg的防除处理最理想,禾本科醉马草死亡率达97.8%,草场质量显著改善。在年降雨量380mm以上,地形平坦的地区采用耕翻重建人工植被亦可达到消灭禾本科醉马草的目的。
Achnatherum inebrians (Hance) Keng is one of main poisonous weeds which is widely distributed over natural grassland and most harmful to livestock. This paper researches two methods to control the weed to use herbicide and ploughing.The result shows the death rate of Achatherum inebrians is up to 97.8% herbicide. Glyphosate (the available compenet is 10% and Glyphosate 11.25kg/ha + soap powder 3kg/ha) and the quality of the range is signally improved. Under the conditions of an annual rainfall of more than 380mm, Achnatherum inebrians can be eliminated by ploughing the grassland and reestablishing the artifial vegetion.
