Development prospect of mixed planting of legume and gramineae forage in winter fallow field in the Yangtze-Huaihe region

With the rapid growth of animal food demand and the implementation of “grain to feed” policy, it is imperative to promote the adjustment of agricultural industrial structure and the comprehensive development of herbivorous animal husbandry. As an important grain production base and animal husbandry development base in southern China, the Yangtze-Huaihe region can completely utilize its winter fallow fields’ production potential, carrying out the cultivation mode of both grain and forage, and therefore provide high-quality forage suitable for local winter production. The production approach of mixed planting of Gramineae and legumes in the winter fallow field can effectively improve productivity and enhance the sustainability of the land. It plays a positive role in increasing farmers' income and promoting the development of herbivorous animal husbandry and the transformation of agricultural ecology in southern China. This study analyzes the development prospect and current situation of forage grass planting in the Yangtze-Huaihe Region, expounding the advantages of the mixed planting of legumes and grass. Mixed planting of high-quality bean and grass and its ecological and economic benefits are also described to provide a reference for grass planting in winter fallow fields in the Yangtze-Huaihe region and similar areas.
