Comparison of Different Grafting Methods on the Roots of Zanthoxylum bungeanum in Hancheng City
To address the issues of high initial investment and slow economic returns in newly estab-lished Zanthoxylum bungeanum gardens in Hancheng City,the experimental research on root grafting improvement techniques for Zanthoxylum bungeanum varieties were conducted.Th root grafting tech-niques in terms of grafting time,scion selection and collection,scion preparation,selection of trees for grafting,and grafting techniques were described.Through comparative analysis of various con-trolled experiments set up during the years of grafting,specific operational methods with high survival rates,faster growth,strong frost resistance,early fruiting,and early attainment of peak fruiting pe-riod were obtained on the basis years of data.These methods can be vigorously promoted and applied in grafting improvement.
