甘肃棘豆(Oxytropis Kansuensis Bunge)是主要分布于我国西北及西南部分草原的多年生豆科植物,其根系发达,枝条繁多,抗逆性强,生物产量巨大。但因其含有有毒成分,不能被草食家畜直接利用,并且常造成大批马、山羊、绵羊等家畜中毒死亡。这就给草畜矛盾本来就很突出的西北牧区带来了更大的威胁。近些年来,虽然研究出了一些有效的化学 Oxytropis Kansuensis Bunge is a perennial leguminous plant mainly distributed in the northwestern and southwestern part of China. Its root system is developed with many branches, strong resistance and huge biological yield. But because of its toxic components, can not be used directly by herbivores, and often cause a large number of horses, goats, sheep and other livestock poisoning death. This brings a greater threat to the northwestern pastoral areas where the contradiction between grass and livestock has always been prominent. In recent years, although some effective chemistry has been developed
