对箭豌豆和一年生黑麦草不同混播比例的研究表明：混播的生物量高于单播，其积累模式为平稳增长型。在同一混播组合中，种间竞争力的强弱随着群落的发育而变化，在生育期间，黑麦草的竞争力高于箭豌豆。在不同混播比例中，随着黑麦草比例的增加，其种间竞争力呈下降趋势。一次性则割可获得较高的混播干物质产量，多次刈割可增加鲜草总产量，但不能提高干物质产量。
The research on the different mix proportion of pea and annual ryegrass showed that the mixed biomass was higher than unicast, and its accumulation pattern was steady growth. In the same mixed-sowing combination, the strength of interspecies competitiveness changed with the development of the community. The ryegrass’s competitiveness was higher than that of arrow-headed pea during the growing period. In different mix proportion, with the increase of the proportion of ryegrass, the interspecific competitiveness decreased. One-time cutting can be obtained at a higher yield of mixed dry matter production, multiple cutting can increase the total yield of fresh grass, but can not increase dry matter production.
