摘　　要：试验旨在筛选适宜在黔西南州栽培的饲草品种。以12个饲草品种为研究对象,采用随机区组设计,设3次重复,共36个小区。通过田间试验比较了同一生长期不同饲草品种在该地区的生产性能、营养品质及相对饲用价值,采用熵权法TOPSIS对各品种进行综合评价。结果表明,12个饲草品种均能在贵州省黔西南州完成整个生育期,适应性较好。普拉达株高和鲜草产量均最高,分别为517.24 cm和123.95 t/hm^(2),其次为绿巨人、3701和大力士。燃力士、WL656HQ和前景的干鲜比、叶茎比均较高。燃力士、前景、WL712、WL656HQ和普拉达的粗蛋白均较高,为19.13%DM~24.63%DM。丰甜的粗脂肪含量最高,为3.36%DM。WL656HQ的粗灰分含量最高,为9.52%DM。曲辰9号、桂青贮5号和兴农单1505的粗纤维含量均较低。曲辰9号的酸性洗涤木质素、中性洗涤纤维和酸性洗涤纤维含量均最低,相对饲用价值最高。研究显示,普拉达、绿巨人、WL656HQ、WL712的综合表现优于其他品种,可作为黔西南州饲草种植的推广品种。The aim of the experiment was to screen the forage varieties suitable for cultivation in the Southwest Guizhou.The growth performance,nutritional quality and relative feed value of twelve forage were compared using a field experiment in the same growth period,and their comprehensive performance data were quantitatively evaluated using entropy weight method TOPSIS analysis.The results showed that the twelve forage can complete the whole growth period in Southwest Guizhou,showing good adaptability.The plant heigh and fresh yield of Prada were the highest at 517.24 cm and 123.95 t/hm^(2),followed by Lüjuren,3701 and Hercules.Burning golem,WL656HQ and Foreground had the higher of dry to fresh ratio and leaf to stem ratio.The crude protein of Burning golem,Foreground,WL712,WL656HQ and Prada were the higher ranged from 19.13%DM to 24.63%DM.The ether extract of Fengtian was the highest at 3.36%DM.The crude ash of WL656HQ was the highest at 9.52%DM.Quchen NO.9,Gui silage No.5 and Xingnongdan 1505 had the lower crude fiber.Quchen NO.9 had the lowest acidic lignin,acid detergent fiber and neutral detergent fiber,meanwhile these relative feeding value was the highest.The study indicates that the comprehensive performance of Prada,Lüjuren,WL656HQ and WL712 are better than others,which can be used as the main variety of cultivation in Southwest Guizhou.
