| 摘 要： | 以槟榔间作可可条件下的可可为研究对象,比较不同修剪方式对其生长、光合作用及产量的影响。结果表明:中度修剪提高可可株高、干周和主枝粗度,重度修剪和仅控冠幅降低可可干周和主枝粗度。中等修剪可可叶片Pn显著高于轻度修剪和仅控冠幅,可能由于修剪提高了新梢叶片叶肉细胞光合作用能力。中度修剪可可徒长枝重量分别比轻度修剪、重度修剪和仅控冠幅显著降低了69.27%、54.69%和57.03%,大大降低了养分消耗,提高产量的同时节省了修剪工作量。综上所述,在槟榔间作可可条件下,采用中度修剪有利于提高光合作用效率,形成健康平衡树形,降低徒长枝养分消耗,提高产量,为槟榔间作可可节本增效技术研究与优化提供依据。

| Abstract: | The effects of different pruning methods on the growth,photosynthesis and yield of Areca Catechu L.intercropping Cacao were studied.The results showed that moderate pruning increased the plant height,trunk girth and main branch thickness of Cacao,while heavy pruning and only crown width control decreased the trunk girth and main branch thickness of Cacao.The Pn of medium pruning Cacao leaves was significantly higher than that of light pruning leaves and only crown width control,probably due to the enhancement of photosynthetic capacity of mesophyll cells in new slightly pruning leaves.Compared with light pruning,heavy pruning and only crown width control,medium pruning significantly reduced the weight of excessive growth of branches by 69.27%,54.69%and 57.03%,respectively,which greatly reduced the nutrient consumption,increased the yield and simultaneously saved pruning workload.In conclusion,under the condition of Areca Catechu intercropping Cacao,moderate pruning can improve the photosynthetic efficiency,form a healthy and balanced tree type,reduce the nutrient consumption of excessive growth of branches,and increase yield,which provides a basis for research and optimization of areca catechu intercropping Cacao costefficiency enhancement technology。 |
