| 摘 要： | 【目的】对密蔽东魁杨梅园夏季修剪的坐果效应进行研究，以明确其夏季修剪量，科学指导杨梅生产。【方法】在相同的管理水平条件下，对10年生密蔽东魁杨梅分别进行夏季轻剪（修剪量控制在全树枝干量的5％左右）、适度修剪（修剪量控制在全树枝干量的20％左右）、重剪（修剪量控制在全树枝干量的40％左右）、不修剪试验，探讨不同修剪量对密蔽东魁杨梅坐果的影响。【结果】夏季不同程度修剪对密蔽东魁杨梅树冠内膛成枝量、内膛坐果量、单株产量及果实品质均有影响，其中以修剪量控制在全树枝干量的20％左右单株产量最高，果实品质较好。【结论】适度修剪可以改善杨梅树冠内膛通风透光条件，促使内膛萌发枝条，树冠内外结果，提高果实产量和品质，适宜在生产上推广应用。

| Abstract: | Objective]The experiment was conducted to study the effects of summer pruning on fruit setting of dense Dongkui Mytica rubra for enhancing its production. Method ] The big branees of 10-year-old trees of dense Dongkui Myrica rubra were used to prune at different levels, viz., light pruning （5%）, moderate pruning （20%）, heavy pruning （40%） to observe the fruit setting rates, the trees with no pruning were treated as control. Results ]The number of branches below the pruned top, weight of fruits, fruit yield per plant and fruit quality were affected by different levels of pruning. The maximum yield of fruits and the best quality was observed in trees in which 20% of total branches were pruned. Con- clusion]Results revealed that moderate pruning enhanced the sunlight transmission in the inner sides of canopy, which resulted into high assimilation of the photosynthates and thereby enhancement in fruit setting on the inner as well as outer branches of the trees. It also resulted in enhanced fruit yield and quality. Our studies clearly indicated that pruning 20% of total branches greatly enhanced the fruits production of Myrica rubra plantations. |
