苎麻用作青贮作物的生产性能评价
Hubei Agricultural Sciences(2018)
Abstract
通过对苎麻(Boehmeria nivea L.)鲜茎叶和混合青贮营养成分及生物产量的测定,结果表明,牧苎0904全年鲜茎叶总产量133.2 t/hm2,中饲苎1号全年鲜茎叶总产量120.9 t/hm2,牧苎0904和中饲苎1号收割平均高度为69.45和65.40 cm.牧苎0904和中饲苎1号营养成分检测前三茬的粗蛋白质、粗脂肪、酸洗纤维(ADF)、中洗纤维(NDF)、粗灰分、Ca、P含量基本一致.以50%苎麻+50%玉米青贮料较100%玉米青贮料的粗蛋白质、粗脂肪含量高,适合作反刍动物的青贮料.
