摘　　要：探索适宜于江苏沿海地区甜高粱和玉米混种青贮模式,并基于成本收益理论探究2种作物混种青贮模式下产生的经济效益和节本增效能力。结果表明,甜高粱和玉米混种模式下的产投比明显优于青贮玉米,且每667 m^(2)平均毛收益更高,是理想的节本增效种植模式;甜高粱和玉米混种青贮下的泌乳净能优于青贮玉米,具有较好的牧场营养价值;在实际饲喂环节,该混合种植模式节本约0.5元/(头·d),畜牧企业能够有效节约饲喂成本。The mixed silage mode suitable for sweet sorghum and corn in the coastal areas of Jiangsu Province was explored in the paper,and the economic benefits and cost-saving and efficiency-increasing ability of the two silage crops were explored based on the cost-benefit theory.The results showed that the benefit-cost ratio of sweet sorghum and corn is significantly better than the control group,with higher average gross yield per mu,which is the ideal cost-saving and efficiency-increasing planting mode.The net lactation energy of sweet sorghum and corn mixed silage is better than that of corn silage,which has better pasture nutrition value.In the actual feeding process,the cost of the mixed planting mode is about 0.5 yuan/(cow·day),which can effectively save the feeding cost of the livestock enterprises.
