| 摘 要： | 在青南牧区“黑土型”退化草地上引种10个早熟禾品种,波伐早熟禾、青海扁茎早熟禾、冷地早熟禾、草地早熟禾、高山早熟禾、高寒肯塔基早熟禾和草地早熟禾巴林、康尼、肯塔基、超优异,通过3年的观测,除波伐早熟禾、青海扁茎早熟禾、冷地早熟禾和草地早熟禾4个品种能适应本区高寒气候,越冬率达80%以上,其余6个品种越冬率差,不能适应本区高寒气候。波伐早熟禾、青海扁茎早熟禾、冷地早熟禾、草地早熟禾4个品种第2年开始能完成完整的生殖生长,并在第2、3年产草量最高,第2年达到种子产量高峰。综合评比,波伐早熟禾、冷地早熟禾、草地早熟禾适应性好,产量较高,可作为本区“黑土型”退化草地植被恢复适宜的草种。

| Abstract: | Through observing and selecting 10 varieties of bluegrass introduced into in "Black Soil Type" degraded grassland in pastoral area of Qinghai-southern for 3 years which were poa poiphagorum,P.pratensis var.anceps,Gand.cv.Qinghai P.crymophila,P.pratensis,P.alpina,P.alpina KBG,P.pratensisl.cv.BALIN,P.pratensisl.cv.CONNL,P.pratensisl.cv.KBG,P.pratensisl.cv.SUPMERIT.The results show that four varieties could be adapted to the climate condition in the puna area and their wintering rates were over 80 percent.The four forages were P.poiphagorum,P.pratensis var.Anceps,P.crymophila,P.pratensis,The wintering rate of another six varieties were poor and couldn't adapt to puna climate condition.The four forages that were P.poiphagorum,P.pratensis var.Anceps,Gand.cv.Qinghai,P.crymophila,P.pratensis could be completed entire procreat grow from second year.The hay yield was highest in the second and the third year.Seeding yield arrived the highest point in the second year.The adaptability and the hay yiele of P.poiphagorum P.crymophila,P.pratensis were better on the basis of comprehensive compare and assess.They were choiceness forage varieties that were fit to rehabilitate the vegetation of "Black Soil Type"degraded grassland. |
