关于光照对果树生长、果实发育和果实品质的影响方面的详尽知识是对果园树冠结构进行合理管理的必要基础,这种管理包括采取适当的修剪以控制树形,选择适宜的根砧以控制树冠大小,以及选择适宜的株行距。作为一个结实单位的树冠的大小和复杂性使那些结果的枝条生长在差别很大的光照条件之下,从接受全部光照到接受一小部分光照。可以料到,在这样不同的光照小气候条件下生长的果实会在 Detailed knowledge of the effects of light on fruit tree growth, fruit development and fruit quality is a necessary basis for a sound management of the canopy structure of the orchard, which includes the appropriate pruning to control the tree shape, the selection of a suitable rootstock to control the canopy Size, and choose the appropriate line spacing. The size and complexity of the canopy as a solid unit allows the branches of those results to grow under widely varying light conditions, from receiving the entire light to receiving a small portion of the light. It can be expected that the fruit that grows under such different light and microclimate conditions will be there
