摘　　要：对当地野生草种麦宾草进行了驯化栽培的初步研究。结果表明:麦宾草在海拔高度3 800m左右的果洛地区在栽培条件下能完成整个生育期生长,栽培当年高度可达到16.0cm,盖度达到60%,第2年株高可达到110cm,盖度达到96%;栽培当年干草产量为1 266.8kg/hm2,第2年、第3年和第4年的干草产量分别为7 959.4kg/hm2,6 462.4kg/hm2,5 244.1 kg/hm2,种子产量分别为1 000.2kg/hm2,880.6kg/hm2,790.5kg/hm2。该草种是适合三江源区黑土滩退化草地植被恢复与重建的优良草种,也是高寒草甸地区建植高质量的生态型或刈用型黑土滩人工草地的优良草种。Domestication and cultivation of local wild Elymus tangutorum have been studied. The results showed that Elymus tangutorum could finish the whole growth period under cultivation in Guoluo region where the altitude is about 3 800m. The height was 16.0cm ,the coverage was 60% in the first year ,and llOcm, 96% in the second year. In first year,the yield of hay was 1266.8kg,/hm2. In the second ,the third year and the fourth year,the yield of hay was 7959.4 kg/hm2 ,6462.4kg/hm2 ,5244. 1kg/hm2, the yield of seeds was 1000.2kg/hm2 ,880.6kg/hm2 ,790.5kg/hm2. respectively. Therefore ,it was a fine species for rehabilitation and rebuilding in black soil beach deteriorated grassland in yellow river , changjiang river and lanchang river.
