Here girdling technology was applied to promote the flowering and fruiting of walnut.Backbone and trunk girdling operations were then performed on the walnut trees that planted in southwest Guizhou Province of China.The feasibility of girdling technology was also evaluated in the test.The result show that the most outstanding performance was achieved to promote the amount of mixed flower branches:When girdling the backbone,the width of girdling mouth was 2～3 cm with the main branch;When girdling the trunk,the staggered girdling with a width of 1～2 cm was adopted with the girdling arc length of 2/3.Therefore,the girdling operation on walnut trees can be expected to significantly promote the formation of walnut mixed flower buds.
