摘　　要：采用在三江源区"黑土滩"种植试验牧草的方法,研究了不同种子处理方式、不同种植方式、不同草种组合对牧草主要生长性状的影响。结果表明,丸粒化技术处理的牧草较未丸粒化技术处理的牧草同时种植后,出苗密度在阴坡样地、阳坡样地分别提高了4.02%、16.04%;并且丸粒化牧草较未丸粒化牧草在单株叶片数、株高、最大根长上也有所增加;直播方式适宜丸粒化牧草及阴坡样地未丸粒化牧草的种植,翻地、耙地、播后镇压方式适宜阳坡样地未丸粒化牧草的种植;同德老芒麦(Elymus sibircus Linn.cv.Tongde)、披碱草(Elymus dahuricus Turcz)的生长状况显著好于青海冷地早熟禾(Poa crymophila Kengcv.Qinghai)和青海中华羊茅(Festuca sinensis Keng cv.Qinghai);同一牧草种类中,单播方式比与燕麦(Avena sativa Linn)组合混播的方式其生长性状指标都有所提高。The influence of different seed treatment methods, planting methods and pasture species on major pasture growth characters was studied by planting pasture on ＂Black soil patch＂ in the source of three rivers. Results indicated that the seedling density treated with pelletizing on adretto and schattenseite increased 4.02 % and 16.04 % respectively compared with non-pelletizing. Meanwhile, leaves number, plant height and largest root length were somewhat increased, pelletizing compared with non-pelletizing pasture. Direct seeding method was suitable for planting of pelletizing pasture and non-pelletizing pasture in adretto sites, and plowing, harrowing and packing after planting method were suitable for planting of nonpelletizing pasture in schattenseite sites; The growth performances of Elymus sibircus Linn.cv.Tongde and Elymus dahuricus Turcz were better than those of Poa crymophila Keng cv.Qinghai and Festuca sinensis Keng cv.Qinghai, significantly. All growth character indexes of mono-culture Avena sativa Linn were somewhat increased compared with mixed culture A. sativa in the same pasture species.
