Aboveground biomass production of switchgrass and sainfoin on Loess Plateau of China

摘要：

In the semiarid, hilly‐gully region in the Loess Plateau of China, it is critical to find sustainable, rational cropping patterns for various grass species.Intercropping has long been used as one dryland farming practice in China, particularly in rainfed areas.While most of the plants used in mixtures have been annual crops, the objective of this study was to investigate biomass production of a perennial introduced grass ( switchgrass, Panicum v irgatum L.) and a perennial legume ( sainfoin, Onobrychis v iciae f olia L.) under a 2 :1 row‐replacement intercropping system compared to a monoculture.
