【摘要】 【目的】研究不同小黑麦材料在川西北高寒牧区的适应性。【方法】以8个小黑麦品种（品系）为试验材料，测定其株高、有效分蘖数、鲜草产量、干草产量及营养价值。【结果】秋播小黑麦的有效分蘖数与产量显著正相关；甘农4号小黑麦的株高、有效分蘖数及产量显著高于其他材料，且粗蛋白含量和干物质消化率最高，酸性和中性洗涤纤维含量相对较低。【结论】甘农4号小黑麦的生产性能和营养价值优于其他材料，适宜于在川西北地区推广种植。更多还原

【Abstract】 【Objective】 To study the adaptability of different varieties(lines) of triticale in alpine pastures in northwest Sichuan.【Method】 Plant height, effective tiller number,fresh yield,hay yield and nutritional value were determined using eight different varieties(lines) of triticale as materials.【Result】 The results showed that the effective tiller number was significantly and positively correlated with triticale yield,and the plant height,effective tiller number and yield of Gannon 4 triticale were significantly higher than other varieties(lines) of triticale;meanwhile, the CP content and DMD were the highest, and the ADF and NDF content was relatively low.【Conclusion】 The production performance and nutritional value of Gannon 4 triticale were better than those of other varieties(lines), and it was suitable to be promoted in northwest Sichuan.更多还原
