摘　　要：为挖掘小黑麦藏饲1号在高海拔地区的最佳栽培技术,本研究以小黑麦藏饲1号品种为试验材料,采用大田裂区设计试验,探究播种方式(条播、撒播)、播种密度(15,17.5,200 kg/667 m2)和有机肥施用量(800,1000,1200 kg/667 m2)对小黑麦藏饲1号生育期、株高、干草产量、营养品质的影响,确定其最佳栽培模式。结果显示,在条播条件下,播种密度为17.5 kg/667 m2、有机肥施用量为1200 kg/667 m2时,小黑麦干草产量(279.7 kg/667 m2)、粗蛋白(3.59%)、粗脂肪(1.26%)、无氮浸出物(53.47%)含量高,粗灰分(5.8%)、粗纤维含量低(32.53%),营养价值高。In order to explore the best cultivation technology of Triticale Zangsi No.1 in high-altitude areas,this study used Triticale Zangsi No.1 as experimental material,and used field split plot design experiment to explore the effects of sowing methods(drilling,sowing),sowing density(15,17.5,200 kg/667 m2)and organic fertilizer application amount(800,1000,1200 kg/667 m2)on the growth period,plant height,hay yield and nutri⁃tional quality of Triticale Zangsi No.1,Determine the best cultivation mode.The results showed that under the condition of drilling,when the sowing density was 17.5 kg/667 m2 and the application amount of organic fertilizer was 1200 kg/667 m2,the hay yield(279.7 kg/667 m2),crude protein(3.59%),crude fat(1.26%),nitrogen free extract(53.47%),crude ash(5.8%),crude fiber(32.53%)and nutritional value of triticale were high.
