[目的]通过不同混播比例、不同播种方式建植混播草地的研究,探索自然降水在500 mm以上的雨养地区,建植优质、高产、稳定与中长利用年限混播人工草地的技术途径.[方法]试验设鸭茅(Dactylisglomerata)与红豆草(Onobrychis viciaefolia)、无芒雀麦(Broumis inermis)与红豆草混播,混播比例为5∶5、4∶6、6∶4三种处理,各处理以1∶1行；2∶2行；3∶3行异行种植；在豆科牧草花期与禾本科牧草抽穗期,测定草地群落各种群组分的密度、高度与产草量,比较分析各处理的草地经济性状表现.[结果]在不同种植方式的处理中,1∶1行的种植方式,各项经济性状指标均优于其它种植方式；在不同混播比例处理中,红豆草与鸭茅混播,以6∶4混播比例的草群产量最高,在1∶1行处理中,平均可产干草1 276.8 g/m2；红豆草与无芒雀麦混播,6∶4与5∶5混播比例的草群产量最高,在1∶1行处理中,平均可产干草1 194.95和1 242.3 g/m2.[结论]试验区草地在建植的当年就表现出良好的长势与较高的生产性能,尤其是豆科牧草的产量大幅度增加,可极大地提升草地的质量.%[Objective] The technical way of planting high quality and high yield, stability and long -term use of mixed artificial grassland were researched based on the different seeding rates and different sowing ways in the area with rainfall of above 500 mm. [ Method] The experiment design set the mixture patterns that were Dactylis glomerata + Onobrychis viciaefolia and Bromus inermis + Onobrychis viciaefolia at the mixed sowing ratio of 5: 5,4: 6 and 6:4 three kinds of treatments and the treatment with 1:1,2: 2 and 3: 3 lines of different planting; when flowering and heading, the density, height and forage yield of community various group were studied and the economic characters were contrasted. [Result]The results showed that; various economic indexes are better than other planting patterns and at 1 line, the forage yield of mixed 6 :4 were higher than other mixed ones and the average yield could reach 1 276.8 g/m2 in Dactylis glomerata + Onobrychis vidaefolia and the forage yield of the ratios 6: 4 and 5: 5 were higher than other mixed sowing rate at I' 1 line, the average yield of which could reach 1 194.95 and 1 242. 3 g/m2 in Bromus inermis + Onobrychis viciaefolia. [ Conclusion ] Good growth vigor and high performance were showed, among which, the increases of legumes yield can greatly enhance the quality of grassland in planting year at the research site.
