| 摘 要： | 本文分析了不同地类与飞播成效的内在关系,提出了选择播区的标准。应用模糊聚类分析方法,划分出飞播草场类型,并提出了适宜的草种组合及播量。试验采用棋盘式和重复式作业法,显著地提高了均匀度及成效。混播草场的建成,从根本上改变了飞播形成的单一的沙打旺草场景观,取得了显著的效益。

| Abstract: | This paper analyses internal relations between various earth's surface and sowing re- sults,and puts forward the criteria of sowing-aera selecting.Grassland types are classified through analyses of fuzzy cluster,and the types of seed mixing and quantity of sowing are obtained.The aerial mixed sowing technique of chessboard and repeated model is used in the study to increase the evenness and result of sowing.The mixed seeding grassland set by plane has fundamentally changed the prairie landscape of simple Astragalus adsurgens pall,and it has achieved obvious benefits. |
