Abstract: Coastal grass belt refers to the development of grass/forage farming systems according to the gradient of salinity along the coastal line, which could help develop grass-based livestock husbandry on saline soil and contribute to food security in China. This review summarizes several successful forage cultivation models in Yellow River Delta, including the forages rotation, rice-triticale/oat rotation, and forest-grass intercropping. We also discussed the biological question that are related to the understanding of the molecular mechanisms of salt tolerance, dissection of molecular modules balancing stress tolerance and biomass production, and development of value-added products of forage grasses. The resolution strategy and realization way of these biological question were summarized.

Key words: coastal grass belt, basic research questions for forage grasses, grass-based livestock husbandry, Yellow River Delta
