Abstract：In order to study the impact of different pruning methods on their growth and yield after the harvest of open-field substrate potted blueberries,the 2-year-old blueberry variety'jewelry'was selected as the research object,and three different degrees of pruning methods(mild,moderate,and severe)were designed for pruning,and the growth,yield and quality indicators of blueberries after pruning were measured.The results showed that after pruning,the overall effect of moderate pruning was the best,with the highest volume index,which was 1.18 m3,the earliest entered the bud stage,the average yield per plant was 4 580.83 g,with 16.54％and 109.23％higher than that of mild shearing and severe shearing;the proportion of large and medium fruits was higher than that of mild shearing and severe shearing.The fruit weight per primary branch and fruit number per branch was more than that of mild shearing and severe shearing,showing significant differences;The quality of secondary branches and single branches were more than that of severe shearing;dry-to-fresh ratio was the lowest,SSC/TA ratio was the highest,and the taste was higher.The economic benefits reached 126 328 yuan/667 m2,and the increase of mild shearing and severe shearing by 16.90％and 112.22％.Comprehensive analysis showed that open-ground base potted blueberries were pruned in moderate amounts,that was,the pruning amount was about 55％of the total number of branches.The blueberries had good yield and economic benefits,and could be promoted and applied in actual production.
