Research On The Key Technology Of Walnut Tree Budding

the purpose of this study is to use non objective walnut tree square budding method to search a set of grafting process and walnut tree diameter size,number of bud grafting Stake reservation number,in order to provide the basis for the operation of technology in the production of walnut tree budding.the walnut trees with the same diameter of the same soil were selected as stock,and the single factor four treatment experiment was set up.The first year short osteotomy twig,second years in new shoots with square budding grafting to breed bud piece.Second years after the start of the three consecutive years to investigate the crown diameter of walnut,the main infection and rot disease situation and the unit area yield.Finally summed up the reasonable number and the number of bud grafting with Stake.the survey results show that the number of reserved chunks in a certain range,the more the number of bud grafting,then crown recovery is faster,the main disease is lighter,faster recovery yield.20 cm-25 cm in diameter and cm interval should be reserved for the 16 walnut tree tree,bud grafting 40 is appropriate.the experiment to explore a high survival rate,fast recovery and canopy and yield,the trunk is not easy to susceptible trees of walnut bud grafting technology,provides the basis for the operation in the production of walnut tree in bud.
