天然草原上收贮的野干草,群众习惯上称之谓“羊草”,实际上羊草(Aneu-rolepidium chinse kitag.)只是其中的主要成份之一。在东北草原上以羊草为建群种形成的植被类型,占相当大的比例,主要作为采草场利用。近年来由于草原利用不够合理,加之旱、涝、盐硷等自然灾害的影响,草原普遍退化,优良牧草减少,劣质牧草增多,产草量下降,造成冬春饲草不足,牲畜抗灾能力减弱。1983年4月末西部地区一场大风雪,就有两万多头(只)牲畜死亡,其原因虽多,但缺草是主要原因之一。
Wild hay stored on natural grasslands, the masses habitually called “Leymus”, in fact Leymus chinensis (Aneu-rolepidium chinse kitag.) Is only one of the main ingredients. In the northeastern grasslands of Leymus chinensis for the formation of vegetation types of vegetation, accounting for a large proportion, mainly used as mining grassland. In recent years, due to the unreasonable utilization of grassland and the natural disasters such as drought, flood and salinization, the grasslands are generally degraded, the fine forage is reduced, the inferior forage is increased, and the yield of grass is reduced, resulting in insufficient fodder in winter and spring and weakened capacity of livestock to resist the disaster. At the end of April 1983, a snow storm in the western region had more than 20,000 dead (only) animals, for many reasons. However, lack of grass is one of the major causes.
