摘　　要：以南高丛蓝莓V3、兔眼蓝莓Brightwell的衰弱大树为试材,研究了不同大枝修剪方式(回缩、重短截、中短截、轻短截)、细弱结果枝修剪量(30%、50%、70%、100%)和留果量对蓝莓衰老树更新复壮和当年产量、果实品质的影响。结果表明:四种修剪方式对蓝莓衰弱树的当年产量、果实品质和新梢生长影响均差异显著。其中,以中修剪、重修剪和回缩处理更有利于大树的更新复壮,修剪越重更新效果越好,但留果量30%的重修剪处理,可以兼顾产量损失和树体更新,更新死亡率低,耐粗放管理,更适宜在实际生产中推广;V3 品种丛生枝条多发枝量大,较Brightwell更易更新,Brightwell品种修剪更方便,省力省工。The effects of different pruning methods (retraction, heavy truncation, medium truncation, light truncation), pruning amount of thin fruiting branches (30%, 50%, 70%, 100%) and fruit retention on regeneration and rejuvenation, yield and fruit quality of blueberry senescent trees were studied. The results showed that the effects of four pruning methods on the yield, fruit quality and shoot growth of blueberry trees were significant. Among them, mid-pruning, re-pruning and retraction treatment are more conducive to the regeneration and rejuvenation of big trees, and the heavier pruning, the better the effect of regeneration. However, the 30% fruitretaining re-pruning treatment can take into account both yield loss and tree body regeneration, lower mortality rate of regeneration, more extensive management, and is more suitable for promotion in actual production. The number of clumped branches of V3 variety is large, which is easier to update than Brightwell, and the pruning of Brightwell variety is more convenient and labor-saving.
