摘要: 试验对‘广益’扁穗牛鞭草和'巫溪'红三叶单播及混播群落生物量、种间竞争力进行了动态研究,结果表明最佳混播组合为75%扁穗牛鞭草+25%红三叶。从整个混播群落看,扁穗牛鞭草生长快,植株高,其竞争力强于红三叶,在竞争中占优势。

Abstract: The dynamical studies on the biomass and interspecific competition of ‘Guangyi’ Limpograss[Hemarthria compressa(L. F.) R. Br. cv. Guangyi] and ‘Wuxi’ Red Clover(Trifolium repens L. cv. Wuxi) in monoculture and mixture were conducted in the experiment. The results show that the optimal mixture combination is 75% limpograss+25% red clover. In all treatment, limpograss grows quickly, and the plant is much higher, so its competition of limpograss in communities is superior to the red clover.

Key words: Limpograss[Hemarthria compressa(L. F.) R. Br.], red clover(Trifolium repens L. cv. Wuxi), biomass, competition, mixture
