| Abstract: | This experiment was to evaluate the producing characteristics of mixed cut-grassland with different ratio of whipgrass(Hemarthria compressa cv."Guangyi") and alfalfa(Medicago sativa cv."Shengshi") by measuring the height of plant,canopy and yield before each cut,and then supply a theoretical basis for the building and management of mixed cut-grassland.The results showed that the treatments of LC2(50% "Guangyi" +50% "Shengshi") and LC1(75% "Guangyi" +25% "Shengshi") were both the optional mixture combinations.In mixed grassland,the height of "Shengshi" was increased and that of "Guangyi" was decreased.And in all treatments,the average of leaf area index(LAI) of mixed grassland was lower than that of monocultured "Guangyi" grassland.Furthermore,the yield of mixed cut-grassland was more than that of monoculture. |
