The invention belongs to the technical field of seedling cultivation and especially relates to a seedling breeding method for walnuts, which includes the following steps: rootstock treatment, grafting, and daily management. The method has simple steps and low seedling breeding cost. Through reasonable selection on rootstocks and scions, affinity therebetween is increased; and before combination, the rootstocks and scions are respectively treated in the aspects of nutrient requirement and disease prevention and control, so that the method can ensure survival rate of the walnuts by more than 99% on the basis of guaranteeing normal growth of walnuts. The method also increases the average Mu yield of the walnuts by more than 17.9% than a conventional grafting method. 本发明属于苗木培育技术领域，特别涉及种核桃的育苗方法；包括以下步骤：砧木处理、嫁接、日常管理；本发明操作步骤简单，育苗成本较低，通过对砧木和接穗的合理选择，提高它们之间的亲和度，在结合之前对砧木和接穗分别进行处理，包括营养成分需求以及病害防治方面，在满足核桃正常生长的同时，最大限度的保证了核桃的存活率，成活率在99％以上，同时核桃的平均亩产量相对于传统嫁接方法提高了17.9％以上。
