Miscanthus, a perennial rhizomatous C4 grass, has emerged as a promising lignocellulosic crop. To avoid competition with food crops, marginal lands especially saline–alkaline soil are being recommended to grow Miscanthus across China. However, the challenges such as high cost and low reproduction coefficient associated with the propagation methods are impeding its large-scale plantation in saline–alkaline soil. In this study, a “two-steps” propagation method was designed, which was comprised of two phases: (1) seedling cultivation and (2) s...
