修剪形状对英红九号茶树蓬面生长与产量的影响

Effects of Different Pruning Shapes on the Canopy Growth and Yield of Yinghong No.9 Tea Plant

为探究冬剪时剪成不同的树形对茶树的蓬面和产量的影响,以英红九号为试验和调查对象,分析采用不同修剪形状(平形和弧形)对茶树蓬面和产量的影响。结果表明,弧形和平形修剪形状的剪后树冠冠幅、叶面积指数和百芽重间无明显差异;而弧形修剪形状的总发芽数、可采摘面以及产量均高于平形。

Taking Yinghong 9 as the test and investigation object,we analyzed the effects of using different pruning shapes on tea tree yield and canopy,in order to explore the effects of cutting into different tree shapes during winter pruning on the yield of tea trees.Results showed that pruning into an arc and a flat shape did not cause a significant difference in the crown width,leaf area index,and 100-bud weight of the cut tree crown.The total number of germination,pickable surface and yield of arc-shaped tree were all higher than those of flat-shaped tree.
