| 摘 要： | 在新疆石河子进行了不同混播比例和不同刈割期对紫花苜蓿Medicago sativa和无芒雀麦Bromus innermis混播草地产量及品质影响的研究。结果表明：以紫花苜蓿50%（7.5 kg/hm2）+无芒雀麦50%（15 kg/hm2）混播比例的混播草地产草量最高，达到21.3 t/hm2，刈割期处理T2（紫花苜蓿初花期）产草量最高。刈割期对紫花苜蓿品质存在着明显的影响。处理T1（紫花苜蓿现蕾期）的粗蛋白含量最高，中性洗涤纤维和酸性洗涤纤维含量最低（P<0.05）；刈割期对混播草地无芒雀麦和紫花苜蓿品质存在一定的影响，其中混播处理A1（紫花苜蓿与无芒雀麦5∶5）紫花苜蓿和无芒雀麦的品质较好。

| Abstract: | The effect of different seeding rates and cutting time on forage yield and quality of alfalfa and smooth bromegrass mixed pasture was studied.The results showed that the forage yield of alfalfa and smooth bromegrass mixed at 50%(7.5 kg/hm2) and 50%(15 kg/hm2) achieved the highest(21.3 t/hm2).T2 treatment(cutting at alfalfa initial flowering stage)obtained the highest yield.Cutting time had significant influence on the quality of alfalfa.Crude protein content in T1 treatment(cutting at alfalfa bud period) wa... |
