摘要:

牧草混播是人工草地的重要种植方式之一,大量研究表明牧草混播具有显著的增产提质效果。了解其种间互作机理并探究其生态系统功能和服务,对于维持混播草地的稳定生产和实现人工草地种植的可持续发展具有重要意义。本研究根据目前国内外研究成果,从种间互补与竞争及地上、地下等方面分析了牧草混播的种间互作机理,从生态系统功能和服务角度论述了混播对牧草产量、品质提升、养分利用、土壤动物和微生物、系统稳定性等方面的影响。最后,指出未来我国人工混播草地研究中应注重有针对地选择特定功能的物种,明确影响物种间互作的因素,同时关注地上-地下耦联机制及草-畜互作等方面。

Abstract:

Use of forage mixtures is one of the important planting practices in establishment of intensively managed artificial grasslands to enhance productivity and quality. Understanding the mechanisms underlying species interactions, and exploration of the ecosystem functions and services are essential to management for stable production and sustainability. Here, based on the recent advances in this topic, we discuss how mixed forage systems affect the outcome of interspecific complementarity and competition in above- and below-ground compartments. Next, we address the effects of mixed-species forage sowings on pasture productivity and quality, recourse utilization, biodiversity of soil food webs, and ecosystem stability. Finally, we emphasize the future challenges for selection of suitable plant species with synergistic properties. Longer-term studies are needed to conclusively demonstrate environmental and production benefits of high-diversity forages.

Key words: artificial grasslands, forage mixture, species interactions, ecosystem function
