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.
