摘要
从 36个苜蓿品种中筛选出适宜海拔 2 550～ 2 80 0 m的高寒山区种植的苜蓿 7个 ,采取灌冬水的措施 ,当年越冬率在 53%～ 92 %。第 2年越冬率在 76.6%～ 10 0 % ,年产干草5736.0～ 11985.5kg/hm2 。第 3年产干草在 3510 .8～ 12 0 0 0 .8kg/hm2 。使苜蓿向高海拔、高寒山区推进 ,对于解决高寒山区特别缺乏优良豆科牧草问题以及对于今后草地更新可资利用的草种具有一定的意义。
From 36 alfalfa cultivars, 7 were screening out for suitable planting in alpine region with an alfitude of 2 550～2 800 m.The overwintering rate in the same year reached 53%～92% and 76.6%～100% in the second year. The annual production of hay was 5 736.0 ～ 1 198.5 kg/hm 2 , and 3 510.8～12 000 kg/hm 2 in the third year. It is considered that this experiment has certain significance in solving the lack of excellent leguminous forages and renewing the useful species in alpine regions.
