摘要: 【目的】研究不同树形葡萄冠层结构的数字化,为精准建立葡萄虚拟冠层,精准量化评价冠层空间结构和葡萄树形的选择提供理论依据。【方法】 建立不同树形葡萄树体结构的三维虚拟模型,以11年树龄3种树形的紫香无核葡萄作为材料,用数字化仪田间测量的枝叶形态参数为基础,利用计算机重建不同树形虚拟树体。【结果】 水平棚架树形的冠层郁闭程度高于其他2种树形;研究虚拟化数字化仪结合计算机软件的方法建立在树体实际生长参数的基础上成功建立虚拟树体,能够在对树体不造成破坏性影响的基础上对树体进行葡萄冠层的枝叶关系以及光合的分析研究;飞鸟树形光截获数值远高于其他2种树形,冠层郁闭程度要小于其他2种树形,光能利用率的较高。【结论】 数字化仪结合紫香无核葡萄品种实际枝叶数据建立整体虚拟葡萄树体可行,以及从光合有效辐射(PAR)和果实品质的角度分析:飞鸟树形是最优树形。

Abstract: 【Objective】 To provide theoretical basis for accurate establishment of virtual canopy and accurate quantitative evaluation of canopy spatial structure and selection of grape tree shape.【Methods】 In this study, a three-dimensional virtual model of different tree-shaped structures were established by using three kinds of purple seedless grapes with 11 years old as experimental materials; Based on the morphological parameters of branches and leaves measured in the field by digital instrument, the virtual tree bodies of different tree shapes were reconstructed by computer.【Result】 The results showed that: With the increase of branch length, the three types of trees would avoid the strong light at noon. In this study, the method of virtual digitizer combined with computer software was established on the basis of the actual growth parameters of the tree body, and the virtual tree body was successfully established, which could analyze and study the relationship between branches and leaves of the grape canopy and photosynthesis of the tree body without damaging the tree body. The interception value of 'bird' tree light was found much higher than that of the other two frames, the degree of self-shielding was smaller than that of the other two frames, and the utilization rate of light energy was higher.【Conclusion】 It was concluded that the digital instrument combined with the actual data of leaves and branches of the local purple sweet seedless grape variety is feasible to establish the whole virtual grape body. From the perspective of photosynthetically effective radiation (PAR) and fruit quality analysis, the tree shape of birds is the optimal tree shape in this study.

Key words: grapes; 3D digitization; different tree shape ; virtual plants; light interception
