摘　　要：为探索杂交构树、蛋白桑在延安北部地区推广的可能性,先后引进了杂交构树、丰驰桑,在延安市安塞区招安镇李塔村进行栽植试验。结果表明,杂交构树、蛋白桑具有抗寒性强、粗蛋白含量高等优点,同时存在管理水平要求较高、产量较南方差距较大等缺点,在延安市北部蛋白桑可以作为调整优化饲料配方结构,促进玉米、豆粕减量替代推广品种,但一定要做到精细化管理。In order to explore the feasibility of promoting Hybird Broussonetia papyrifera and protein mulberry in the northern region of Yanchuan,we introduced Hybird Broussonetia papyrifera and Chifeng protein mulberry and conducted a planting experiment in LiTa Village,Zhao'an Town,Ansai District,Yanchuan City.The results showed that Hybird Broussonetia papyrifera and protein mulberry have strong cold resistance and high crude protein content,but also have disadvantages such as high requirements for management level and large yield gap compared to the southern region.In the northern region of Yanchuan City,protein mulberry can be used as a variety for optimizing the feed formula structure and promoting the reduction of corn and soybean meal,but it must be managed meticulously.
