(一) 理論根据西北的天然草原上,特別是放牧过重的亞高山草原及高山草原的較干燥处,往往有大面积的醉馬草叢。(Sfjpa inebrians或Achnafherum inebrians)由于这是一种毒性頗强,不为家畜釆食的毒草,其他牧草尽管已为过重的放牧所严重的破坏,但它仍能茂盛生长,芃息不已,严重降低了草原的生产力。在初春牧草缺乏,家畜飢餓时,且可为家畜采食而引起中毒和死亡。在这些地区如何清除醉馬草,是一项应該考虑的課題。用焚燒草叢的方法加以清除,方法簡便,易于推广,这是进行本試驗的主要目的。 (A) Theory According to the natural grassland in the northwest, especially over-grazing sub-alpine grasslands and alpine grasslands in the more dry, often have a large area drunk horse grass. (Sfjpa inebrians or Achnafherum inebrians) Since this is a toxic toxin that is not consumed by domestic animals, other grasses, despite being severely damaged by overgrazing, are still flourishing, enduring, and grave Reduce grassland productivity. Lack of pasture in early spring, livestock hungry, and can cause poisoning and death for livestock feed. How to rid Drunken Ways in these areas is a topic that should be considered. The method of burning grass to be removed, the method is simple and easy to promote, which is the main purpose of this experiment.
