摘　　要：针对西藏地区饲草季节性短缺问题,本研究在拉萨河谷农区引进粮饲兼用小黑麦(Triticosecale Wittmack)品种,以实现粮食与饲草生产的双重增效。对6个小黑麦品种(系)(豫饲601、豫饲602、中饲1048、中饲1640、中饲1877和中饲3241)进行春播试验,比较其在灌浆期和成熟期株高、鲜草产量、干草产量、茎叶比、营养品质以及成熟期籽粒产量及其构成因素。研究发现,豫饲601和中饲3241在饲草产量和营养品质方面表现出色,其中豫饲601在饲草产量和营养品质上更具优势。结论表明,豫饲601和中饲3241在西藏拉萨河谷农区春播的饲草产量高,具有推广种植的潜力,有望为该地区种植业结构优化调整做出贡献。Aiming at the severe seasonal shortage of forage grass in Xizang,the Lasa River Valley agricultural region,recognized as a key area for grain and artificial forage grass production,introduced the triticale varieties for both grain and forage.The goal was to achieve a win-win situation in both grain production and forage grass supply.Six triticale varieties(lines)(Yusi 601,Yusi 602,Zhongsi 1048,Zhongsi 1640,Zhongsi 1877 and Zhongsi 3241)were sown in spring.We compared their plant height,fresh grass yield,hay yield,stem to leaf ratio,nutritional quality,and grain characteristics during filling and maturation stages.The findings indicated that Yusi 601 and Zhongsi 3241 excelled in both yield and nutritional quality.Notably,the Yusi 601 variety(line)not only achieved higher yields but also demonstated significant advantage in nutrient composition.Both Yusi 601 and Zhongsi 3241 exhibited high forage yields when spring-sown in the Lasa River Valley agriculture region,indicating their potential for widespread adpotion in addressing forage shortages.
