摘　　要：通过对夏收后不同复播方式下饲草料地上生物量和营养成分进行分析,并利用隶属函数值法评价其综合经济效益。研究结果表明,混播较单播饲草料的产草量和粗蛋白含量明显高,粗纤维含量降低。6种复播方式中初岛燕麦+中豌六号混播组合所获取的综合经济效益最高,这为伊犁地区夏收复播饲草料模式的选择提供参考。Through comparative analysis of the forage biomass and nutrients under different multiple sowing methods after the summer harvest, and evaluate the comprehensive economic benefit by using subordinate function values. The results show that, forage grass production and crude protein content of mixed sowing was significantly improved than the unicast, crude fiber content was decreased. Mixed sowing combinations which obtained the highest comprehensive economic benefits is Arena sativa L. ＋ Pisum sativum L. in six kinds of re-sowing methods,this can provide a reference for the re-sowing forage mode selection after the summer harvest in Yili Prefecture.
