摘　　要：本文阐述了六倍体小黑麦(×Triticale Wittmack)的发展历史、形态习性、饲草产量、营养品质、抗逆性、生产现状及应用前景,发现小黑麦产草量高,茎叶蛋白质、赖氨酸、粗脂肪含量高,粗灰分、无氮浸出物、中性洗涤纤维、酸性洗涤纤维含量低,饲用品质较小麦(Triticum aestivum)、玉米(Zea mays)、燕麦(Avena sativa)、高粱(Sorghum bicolor)好,籽粒和饲草经济效益高,抗逆性强,适应性广,小黑麦作为饲草在畜牧业中具有更广泛的利用价值,特别是在高寒牧区需加大其研究和发展的必要性和迫切性。This study analyzed the breeding history,morphological features,forage yield,nutritional quality,stress resistance,production status,and form of use of hexaploid Triticale( × Triticale Wittmack). It showed that Triticale has a high yield,high levels of protein,lysine,and crude fat,and low ash,low nitrogen-free extract,low neutral detergent fiber( NDF),and low acid detergent fiber( ADF) in the stem and leaves; the forage quality of Triticale is higher than that of wheat( Triticum aestivum),maize( Zea mays),oat( Avena sativa),and sorghum( Sorghum bicolor),and it has greater economic benefits regarding grain and forage,high resistance,and wide adaptability. Triticale is highly valued in animal husbandry as forage. We should increase the necessity and urgency of research and development on Triticale in alpine pastoral regions.
