不同修剪方式对杨梅树冠、产量及品质的影响研究

Effect of Pruning Methods on Crown, Yield and Quality of Myrica rubra

以浙江省临海市13年生东魁杨梅为试材,研究不同修剪方式对杨梅产量、品质及效益的影响。结果表明:大枝修剪树冠高度下降最明显,为3.02 m,显著低于对照4.78 m;株产最高,为41.67 kg,显著高于对照株产量的15.67 kg;果实贮藏性最好,贮藏3天腐烂率40%,显著低于对照的100%;其他树冠冠径、叶片叶绿素含量、可溶性固形物、单果重、硬度、色泽等方面无显著差异。

The 13a Myrica rubra trees were used as materials,and the effect of different pruning methods on tree crown,fruit yield and quality of M.rubra were studied.The results showed that after pruning of big branches,the crown height was lowered obviously,which was 3.02m,significantly lower than that of the control (4.78m),and the yield was the highest (41.67kg),significantly higher than that of the control (15.67kg);the fruit storage property was the best,the rotting rate after 3days'storage was 40%,significantly lower than that of the control (100%),and there was no significant difference in the tree crown diameter,chlorophyll content of leaves,the soluble solids of fruit,the single fruit weight,the hardness and the color of fruit.
