摘　　要：为探讨合理的亚热带地区冬季牧草高产、高品质种植模式,本研究通过将多花黑麦草(Lolium multiflorum)分别与4种豆科牧草苕子(Vicia dasycarpa)、豌豆(Pisum sativum)、紫云英(Astragalus sinicus)、白三叶(Trifo-lium repens)进行混播,测定不同组合的生产性能和营养特性指标。结果表明,混播组合均表现出较好的适应性和鲜草产量以及良好的营养特性;在刈割3次的情况下,多花黑麦草+紫云英、多花黑麦草+豌豆、多花黑麦草+白三叶、多花黑麦草+苕子和多花黑麦草+苕子+紫云英组合的鲜草总产量分别为44 863.33、43 923.33、47 003.33、46 470.00和37 970.00kg.hm-2,豆禾比分别为0.076、0.198、0.085、0.116和0.137;在品质方面,多花黑麦草+苕子和多花黑麦草+白三叶组合的营养产出量较优,但前者粗蛋白总产量最高,各项营养产出量中,多花黑麦草+豌豆组合与多花黑麦草+紫云英组合较接近,但稍低于多花黑麦草+苕子和多花黑麦草+白三叶两个组合。综合分析比较不同种植模式下的产量和品质,以多花黑麦草+苕子和多花黑麦草+豌豆两个组合为最佳。In order to determine the regions with high, fresh yield, dry best mixture-plant group of different forages in winter for subtropical mass content and nutrient content, an study was conducted on planting Lolium multiflorum with four kinds of leguminous forages, including Vicia dasycarpa, Pisum sativum, Astragalus sinicus, and Trifolium repens respectively. Results showed that, all mixture-plant groups performed well at fresh yield and nutrient content. The total fresh yields of L. multiflorum＋A, siniscu, L. multi florum ＋P. sativum, L. multi florum＋ T. repens, L. multi florum＋V, dasycarpa, and L. multi- florum＋V, dasycarpa＋A, sinicus were 44 863.33, 43 923.33, 47 003.33, 46 470.00, and 37 970.00 kg ·ha-1 , and the legume gramineae ratio were 0. 076, 0. 198, 0. 085, 0. 116, and 0. 137 respectively. Refer to the nutrition, L. multi florum＋ V. dasycarpa and L. multi florum＋ T. repens had better performance than other groups, but L. multiflorum＋V, dasycarpa had a higher total crude protein content. L. multi- florum＋P, sativum and L. multiflorum＋A, siniscu had similar nutrition contents, but their nutrition contents were a litter lower thatn L. multiflorum＋V, dasycarpa and L. multiflorum＋T, repens. Based on the analysis and comparison on yield and quality of different groups, the optimum groups are L. multi- florum＋V, dasycarpa and L. multi florum＋ P. sativum.
