几个多年生牧草品种引种试验总结

A SUMMARY REPORT ON INTRODUCING EXPERIMENTS OF ELITE PERENNIAL FORAGE CULTIVARS

1985～1989年对八个多年生牧草品种的引种试验结果表明,公农一号紫苜蓿的产草量最高,五年生者每公顷为9.11吨,蒙古冰草的产草量最低。供试各品种均可在本地区采种,以肥披碱草的产种量为最高,四年平均每亩为57.95公斤。两个苜蓿品种的干草产量呈持续上升的趋势,种子产量每亩为10公斤左右。

From 1985 to 1989,we introduced and tested eight elite perennial forage cultivars-Awnless Brome(Bromus inermis), Siberian wildrye(Elymus sibericus), Leafy siberian wildrye,Tall siberian wildrye,Mongolian wheatgrass(Agropyron mongolicus),Alfalfa GN-1 and Alfalfa ZhD. Results indicate that the hay yield of alfalfa GN-1 is the highest one among them. The five-year-old alfalfa GN-1 plots can give 9.11t/ha. Meanwhile, the hay yield of Mongolian wheatgrass is the lowest. In fact,all of the above mentioned cultivars can produce mature seeds in this area. The four-year-old Tall Siberian wildrye plots can give 868.25kg of mature seeds per hectare. It is the highest yield of seed among them. The seed yields of the two alfalfa cultivars are about 150kg/ha,respectively. We noticed that the hay yields of the two legume cultivars tend to getting higher and higher in our plots.
