Abstract: Six annual-forage production systems,yield,and seeding-season order have been studied in Southwestern Sichuan Province.They are ryegrass-corn,ryegrass-sorghum×sudangrass,triticale-corn-corn,triticalesorghum×sudangrass,ryegrass+vetch-corn,and ryegrass+vetch-sorghum×sudangrass.Results show that the total forage dry-matter yield of all the six varieties averaged 30×103kg/hm2 plus per year,with that of triticale-sorghum x sudangrass the highest,amounting to 36.7×103kg/hm2 per year.The seeding period of the six varieties are efficiently organized,their productive period lasts more than 320 days a year,and their cropping frequency has reached 5~8 times per year.

摘要: 在川西南研究了多花黑麦草(Lolium multiflorum)-玉米(Zeamays)、多花黑麦草-高丹草(Sorghum×S.sudanes)、小黑麦(Tirticoseale wittmack)-玉米-玉米、小黑麦-高丹草、多花黑麦草+光叶苕子(Vicia villosa)-玉米和多花黑麦草+光叶苕子-高丹草6个一年生牧草生产系统的产草量和草种季节配置。结果表明:6个系统的干草产量都达到30×103kg/hm2以上,其中最高的小黑麦-高丹草系统达到36.7×103kg/hm2;6个系统都形成了良好的草种季节配置,生长期达到320d以上,一年的总收获次数为5~8次。
