摘要
在新疆天山北坡中山带选用紫花苜蓿(Medicago sativa)、红豆草(Onobrychis viciaefolia)、无芒雀麦(Bromus inermis)、冰草(Agropyron cristatum)、披碱草(Elymus dahuricus)等8种牧草,旱作建植豆禾混播、豆科及禾本科单播多年生人工草地。运用AHP和DTOPSIS分析法进行产量、营养品质、土壤养分综合比较,旨在筛选适宜于该区域及类似生态区域推广种植的旱作人工草地类型。结果表明:在本地区最适宜的混播人工草地类型是红豆草+无芒雀麦+冰草+苇状羊茅混播;最适宜的单播人工草地类型是红豆草。
In order to screen out the optimal forage species grown in the middle zone on northern slope of Tianshan mountains, Medicago sativa Linn, Onobrychis viciaefolia Scop, Bromus inermis Layss, Agro pyron cristatum Gaertn, Elyraus dahuricus Turcz, Festuca arundinacea Schreb, Psathyrostachys j uncea Nevski, Elymus sibiricus Linn were used as experimental materials to establish artificial grassland of gras- ses and legume grown in monoculture or in mixture. In the experiments forage yield, nutritional quality and soil nutrient were analyzed by AHP and DTOPSIS methods. The results showed that in this area the best mixed seeding is Onobrychis viciaefolia Scop+ Bromus inermis Layss+ Agropyron cristatum Gaertn+ Festuca arundinacea Schreb, and the best single seeding is Onobrychis viciaefolia Scop.
