| 摘 要： | 通过披碱草与羊草混播进行草地改良，播种当年产草量为1200kg·hm^-2，植被覆盖度达70％。第二年产草量为3750kg·hm^-2，植被覆盖度达80％。第三年产草量为4500kg·hm^-2，植被覆盖度达90％。是防止苏打盐碱土草原退化的有效措施。

| Abstract: | Analysis of mixed sowing Dahuria wildregrass and Chinese leymus to improve grassland was conducted, The results showed that the amount of grass yield was 1200 kg·hm^-2 in the first year and the covered rate of vegetation was 70%, In the next year,the amount of grass yield was 3 750 kg·hm^-2 and the covered rate of vegetation was 80 %. In the third year the amount of grass yield was 4 500 kg·hm^-2 and the covered rate of vegetation was 90%. It indicated that it was an effective measure to prevent grassland from getting worse in soda saline-alkali soil. |
