| 摘 要： | 采用L9(34)正交设计,利用草种组合、施肥量、播种方式、豆禾比例进行4因素3水平试验,探讨退耕坡地草地建设方式,试验结果表明:退耕坡地草地的建植首先需要考虑草种的搭配,其次是禾本科和豆科牧草的比例,第三是肥料的使用,第四是播种方式。在贵州中部地区退耕坡地适宜的草地建植方式为:草种为鸭茅+苇状羊茅+白三叶+多年生黑麦草,豆:禾=1:9,肥为N:P2O5:K2O=20:30:20,播种方式为翻耕条播。

| Abstract: | Adopt L9 (34)perpendiculaeity design, Utilize the seed assembled, Applying fertiliaer amount, Sowing style, The peas and grass proportions are carried on four elements three hydraulics test. The experiment is showed:the seed species combination was the key factor,the peas and grass proporionswas the second. Third is the applying fertilizer. The 4th is sowing style. The optimal combination on retreats plow grassland in the GuiZhou area : Dactylis glomerata+fescue+white clover+perennial, grass+peas=1:9, N: P2O2: K2O=20 : 30 : 20, the sowing style was drilling. |
