Brief introduction of high efficiency forage planting system in south of China

The present research reviewed the forage planting systems in south of China, mainly including the graingrass rotation system, tall grass planting system, perennial mixed pasture system, and forage maize (Zea mays)Italian ryegrass （Lolium multiflorum） rotation system. The research progress in the planting system of forage maizeItalian ryegrass rotation was elaborated in detail, including breeding new forage varieties, high yield cultivation technology, utilizing rate of forage by livestock, temporal and spatial distribution of planting system. Finally, the problems and prospects in theoretical research and application were also discussed for the future use in practice.
