以 5年生纺锤树形的香梨为试材 ,研究了树冠内的光照分布及其对果实品质的影响。结果表明 ,树冠从外围到内膛 ,从上层到下层 ,光照强度递减 ,且光强的垂直分布与树冠层次呈极显著相关。南北行向的香梨园树冠东西两侧光强高于南北两侧。果实着色面积随着生部位光照的增强而增大。果实可溶性固形物含量与光强呈极显著正相关
The 5-year-old spindle-shaped pear was used to study the light distribution inside the canopy and its effect on the fruit quality. The results showed that the light intensity decreased gradually from the periphery to the middle of the canopy, from the upper layer to the lower layer, and the vertical distribution of light intensity was significantly related to the canopy level. North and south to the pear garden crown light intensity on both sides of things higher than the north and south sides. Fruit coloring area with the illumination of the growing parts of the increase. Soluble solids content and light intensity showed extremely significant positive correlation
