| 摘 要： | 分析了多年生牧草4个混播组合连续4年的产量,结果表明:在4个组合中,以组合Ⅳ的产量最高,3年(播种当年除外)的平均鲜草产量为54 152.7 kg/hm2,干草产量为12 463.1 kg/hm2,与其他组合的产量差异达极显著水平,为四川省高寒牧区退耕还草以及人工草地的建设提供了科学的草种组合。

| Abstract: | Forage yields of mixture sowing combinations of perennial grasses from 2001 to 2004 were determined in this paper.The results demonstrated that in four combinations,combination(Elymus dahuricus 5(kg/hm~(2)),Lolium perenne 10 kg/hm~(2),Elymus sibiricus 5 kg/hm~(2),Medicago sativa 30 kg/hm~(2)) had the highest forage yield,average fresh weight and hay yield of three years(except for the planting year) were 54.152 t/hm~(2)and 12.463 t/hm~(2) respectively.And comparing with other combinations,the difference was significant at 0.01 level.It was the best combination in grassland planting and returning grassland from cropland of Sichuan Alpine Pasture Region. |
