【摘要】 通过营养体移栽和种子繁殖两种途径 ,对当地野生草种草地早熟禾进行了驯化栽培的初步研究 ,试验结果表明 :草地早熟禾在海拔高度 40 0 0m左右的果洛地区在栽培条件下能完成整个生育期生长 ,栽培第 2年株高可达到 70cm以上 ,第 2年和第 3年的干草产量分别为 62 65kg hm2 和 5 692kg hm2 ,种子产量分别为 690kg hm2 和 64 5kg hm2 。具有发达的根茎繁殖能力 ,草地早熟禾既能进行种子繁殖也能进行根茎无性繁殖 ,是适合三江源区“黑土型”退化草地植被恢复与重建的优良草种 ,也是在高寒草甸地区建植高质量的打草或放牧人工草地的优良草种。更多还原

【Abstract】 Tame and cultivation of local wild Poa partensis have been studied through cultivation of nutritive organ and zoogamy of seeds,and the result have indicated that Poa partensis could finish the whole breeding period under cultivation in Guoluo region where the altitude is about 4 000m.The height was 70cm in the second year,and the yield of hay was 6 265kg/hm 2and 5 692kg/hm 2,the yield of seeds was 690kg/hm 2 and 645kg/hm 2 in the second and the third year,respectively.The agamogenesis of root system and zoogamy of seeds could carry out,and agamogenesis capacity of root system for Poa partensis was very upgrowth.Therefore,it was a choiceness species that was fit to rehabilitation and rebuilding of “black soil type”deteriorated grassland in of yellow river,changjiang river and lanchang river and it was also fit to establish artificial grassland for grazing or cradling hay. \ \更多还原
