摘要
干寒地区金红苹果乔砧密植,不同密度、树型、株高、叶幕厚度,对树冠内光的水平分布和垂直分布密切相关。树冠内光照强度直接影响树体的花芽形成、开花坐果、果实的产量、质量。只有合理密植,才能充分利用光能,实现早果、丰产、优质。适宜的株行距为2m×4m,树高3.5m^4 m,树形为自由纺锤形。树体产量、质量形成集中分布于树冠外围1 m左右的范围,冠内相对光强在23%,是丰产优质的基线。
In arid - cold region, closely planting Jinhong apple＇s aborization stock, shape of tree, tree height and the canopy thickness were related to the distribution of the illumination inside the tree crown in perpendicularity and horizon. The intensity of light inside the tree crown influence flower bud of the tree body, bloom, fruit - setting, yield and quality of the fruit. Only rational close planting , then can make use of light energy well, bear fruit early, high yield and superior quality can be got. The reasonable spacing in the rows and lines is 2×4m, the tree height is from 3.5 to 4m, the shape of tree is a fusiform . The yield and mass of tree mainly distribute in one meter or so around the tree crown, relative intensity of illumination inside the tree crown is 23%, which is a base line for high yield and superior quality.
