近年来,由于自然环境恶化,荒漠化加剧,以及过度放牧等不利因素的影响,对羊草草甸草原构成了严重威胁。因此,羊草草甸草原的保护和人工草地的重建已引起关注。根据羊草可进行无性繁殖和有性繁殖的特点,将重度退化的天然羊草草场、弃耕地、撂荒地和退耕地进行翻、耙、播种优良羊草种子,建立稳产高产的羊草人工草地是改变吉林西部生态环境的有效方法,也是迅速提高草地生产力的重要措施。
In recent years, due to the deterioration of the natural environment, desertification, and over-grazing and other unfavorable factors, it posed a serious threat to the meadow grassland. Therefore, the protection of the meadow grassland of Leymus chinensis and the rebuilding of artificial grassland have attracted much attention. According to the characteristic of asexual reproduction and sexual reproduction of Leymus chinensis, the natural degraded Leymus chinensis grassland, abandoned farmland, fallow land and returned farmland were turned over, harrowed and sown with good Leymus chinensis seeds to establish a stable and high-yield Leymus chinensis artificial grassland It is an effective way to change the ecological environment in the west of Jilin Province and also an important measure to rapidly increase grassland productivity.
