| 摘 要： | 研究5种禾本科牧草与草原二号苜蓿在不同混播方式下种群的生长高度、种间竞争率（CRi）及产草量。结果表明：草原二号苜蓿的生长不受单播、混播的影响,混播促进了禾本科植物的生长。随着豆科播种量的增加,各试验小区的产量增加。人工草地较天然草地有明显的增产作用。混播人工草地比单播人工草地又有显著的增产效应,其中2/3草原二号苜蓿＋1/3披碱草的混播组合比其他组合增产现象明显。综合结果表明,草原二号苜蓿和缘毛雀麦的混播组合具有合理的禾/豆比例和较高的生产力水平,为较合理的物种组合。 |

| Abstract: | Five gramineous grasses and Medicago varia were used to study the productivity under different mix-sowing treatments by measuring the height,competition rate(CRi)and aboveground biomass.The results showed that the height of Medicago was not influenced and the height of gramineous grasses was promoted by different mix-sowing treatments.The aboveground biomass in different plots increased with the seeding rate.Aboveground biomass was significantly increased especially in the treatment of 2/3 Medicago+1/3 Elym... |
