果树密集、枝条杂乱重叠,使树冠内层树叶遮蔽而减少阳光的透入,造成枝条发育不良和影响果实着色。利用光的反射,以人工辅助日照方式使树荫部分也能得到适量的日光,以改善果实均匀着色。光的反射材料,目前台湾采用两种,一是PE塑料银色布。成品一面为银色另一面为黑色,可裁成块状平铺树下, Intensive fruit trees, branches messy overlapping, so that the inner canopy shade and reduce the sun’s penetration, resulting in poor growth of branches and affect the fruit coloring. The use of light reflection, artificially assisted sunshine way to make the shade part can get the right amount of sunlight, to improve the uniform fruit coloring.
