Abstract:: The effect of different pruning modes on new branchs and available buds of ‘Xiangling’ walnut was studied.The results showed that different pruning modes significantly affected the number,length,diameter and length of new shoots of ‘Xiangling’ walnut.The output of buds was influenced by the number,length,diameter,and the occurrence rate of the secondary branches of the new branches.The recommended length of leaving stake was 10-20 cm for ‘Xiangling’ walnut in the south area of Shaanxi,effective buds were 583.2 more than no pruning on average,and the output of the average available buds increased 116.8% than CK(no pruning).The shorter length of leaving stake,the later the length growth peak of the new shoot comes.
