Walnut resources in our province is rich, and has a long history of cultivation, but the production areas have traditionally habitually breed walnut breeding methods, using this method to breed walnut trees. Generally about 10 years to start the result. Is collected according to the individual premature walnut, in the offspring of individuals also showed significant differences. Practice has proved that the method of grafting walnut grafting can not only advance the results, early yield, and can maintain the parent’s fine traits, can get the same high-quality walnut .So walnut grafting for the realization of walnut cultivation and breeding, variety and increase yield and quality, Promote the development of walnut production is of great significance.Through the test of the past two years, demonstration, the masses initially look
