| 摘 要： | 连续13年测定了由白三叶(Trifolium repens)、多年生黑麦草(Lolium perenne)等5种牧草混播形成的群落的地七生物量,以比较各群落的稳定性.结果表明,地上生物量与物种数成正比,复杂组合的地上生物量高于简单组合.V4组合红三叶(Trifolium pratense)+白三叶(T.repens)+多年生黑麦草(L.perenne)+无芒雀麦(Bromus inermis Leyss)+紫羊茅(Festucarubra)]地上生物量最高.与其它群落比较差异极显著p<0.01);V1组合(红三叶(T.pratense)+多年生黑麦草(L.perenne)]对杂草的抗性和竞争力最差,群落最不稳定;V3组合(白三叶+紫羊茅)对杂草具有很强的抗性和竞争力,群落稳定性最好. |

| Abstract: | The aboveground biomass of each community make up of five kinds of forages,Trifolium repens,Lolium perenne,Trifolium pretense,Bromus inermis Leyss,Festuca rubra was continuously measured for 13a,which was in order to study the stability of mixed communities under the different components,The results showed there was a positive correlation between the aboveground biomass and the number of species,the aboveground biomass of the complex combination was more than that of the simple combination. The aboveground ... |
