Patent number: 11240955Abstract: Provided is a method for planting a mixed forest of yew trees and fig trees. Yew trees and fig trees are interplanted based on characteristics of yew trees and fig trees. A seedling bed method is used in the plain zones, and a terrace field method is used in mountain zones in order to improve land utilization rate and make full use of complementary advantages of ecological niches. In the present disclosure, ground and underground spaces on tree growing site are fully used. Fig trees grow fast and have large leaves, thus shading part of sunlight for yew trees and savings costs required for building shade shelters for yew trees. By using the method for constructing a mixed forest in the present disclosure, the constructed mixed forest not only allows for increase of biomass, but also provides higher paclitaxel content in yew trees than that in pure forest.Type: GrantFiled: June 10, 2020Date of Patent: February 8, 2022Assignee: Northeast Forestry UniversityInventors: Chunying Li, Chunjian Zhao, Yujie Fu, Weiran Su, Yuzheng Li, Jiajing Guan
