【摘要】：我国甘薯产地主要分布在淮海平原、长江流域和东南沿海各省,产量大,是良好的居民鲜食、轻工加工和动物饲用资源。甘薯、薯藤和加工业副产品富含淀粉、果胶和膳食纤维等,水分含量高,不易储运,易腐败变质,综合利用率低,废弃率高。甘薯、薯藤和薯渣是常用饲料,饲用时存在明显的区域性、季节性和经济性特点。在产地农户习惯用煮熟和青贮后的薯块和薯渣饲喂畜禽。利用微生物发酵技术处理薯渣,可提高其营养价值。探索提出产区利用熟制、青贮、鲜饲等形式相结合和加工薯渣制备生物饲料的甘薯资源饲用新模式,可为我国甘薯种植、食用、加工和饲用的适度平衡提供借鉴。
[Abstract]:Sweet potato producing areas in China are mainly distributed in Huaihai Plain, Yangtze River valley and southeast coastal provinces, and the yield is large. It is a good resource for fresh food, light industry processing and animal feeding.Sweet potato, potato vines and by-products of processing industry are rich in starch, pectin and dietary fiber, etc. The water content is high, it is difficult to store and transport, it is easy to corrupt and deteriorate, the comprehensive utilization ratio is low, and the waste rate is high.Sweet potato, tuber vines and potato dregs are common fodder. There are obvious regional, seasonal and economical characteristics in feeding.Farmers used to feed livestock and poultry with cooked and silaged potatoes and dregs.The nutrient value of potato dregs can be improved by using microbial fermentation technology.In this paper, a new forage model for the production of sweet potato was proposed, which could be used as a reference for the proper balance of planting, eating, processing and feeding of sweet potato in our country by combining and processing the biological feed of sweet potato dregs in the production area, such as ripening, silage, fresh feeding and so on.
