密蔽东魁杨梅园夏季修剪的坐果效应
Effects of summer pruning on fruit setting of dense Dongkui Myrica rubra
摘要
Abstract
[Objective]The experiment was conducted to study the effects of summer pruning on fruit setting of dense Dongkui Myrica rubra for enhancing its production. [ Method ] The big brances 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. [Conclusion ] 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.关键词
