摘　　要：以3个品种的藜麦为研究对象,通过测定藜麦植株在不同生长时间的株高、真叶数、叶绿素含量、茎叶比、产量、纤维素、半纤维素、木质素、脂肪以及粗蛋白含量变化,确定作为青贮饲料的藜麦品种以及最佳采收时间。结果表明:格藜、蒙藜、条藜可分别在95,95,80 d时适宜采收作为青贮饲料的原材料;综合理化指标以及营养指标可知,蒙藜农艺性状、产量以及营养指标均优于其他品种。由此,蒙藜在生长约95 d时适合作为青贮饲料的原材料在吉林省种植。Three varieties of quinoa were used to determine the optimum harvesting time for silage by measuring the height,number of true leaves,chlorophyll content,stem to leaf ratio,yield,hemicellulose,lignin,fat and crude protein content of quinoa plants at different growth time.The results showed that Chenopodium glaucum,Chenopodium mongolicum and Chenopodium striatum could be harvested as raw materials for silage at 95 days,95 days and 80 days respectively;According to the comprehensive physical and chemical indexes and nutritional indexes,the agronomic characters,yield and nutritional indexes of Chenopodium mongolicum were better than those of other species.Therefore,Chenopodium mongolicum is suitable to be planted in Jilin province as the raw material of silage when it grows for about 95 days.
