Abstract

To enhance the growth vigor and improve cultivation resistance of Juglans regia,taking early-bearing breeds "Bokezao","Kelongzao","Zhenzhu","Chuan Xiang","Liaoning 1" and late-bearing breed "Qingxiang" as the experimental materials,studies were made of the influence of different pruning methods on the sapling growth of different varieties of Juglans regia.The results showed that (1) bud number decreased with the increase of pruning intensity,while the ability of bud into branches rose with the increase of pruning intensity.(2)The growth of new shoot elongation and diameter showed heavy pruning > middle pruning > light pruning > CK,and there was a positive correlation between them.In the six Juglans regia varieties,Bokezao was the best.(3) The leaf growth showd heavy pruning > middle pruning > light pruning > CK,the Bokezao and Kelongzao's leaf length increased obviously.(4)Pruning was timely done in the next spring after planting,heavy pruning was main and middle pruning was as supplement.The determined height of stem was 30 cm~50 cm.
