我们知道,植物组织器官的分化与阳光有密切关系。向阳面的枝叶,由于长期处在阳光充沛的生态条件下,叶面角质层和栅栏组织较为发达,气孔数目较多,细胞体积也较小,光合作用和蒸腾作用都较强。背阴面光照弱、温度低、湿度大,树木为适应其环境,则形成了不同于向阳面的结构和特性。这样就构成了树木不同方向的结构和物理、化学性质上的差异,使树木本身形成了阴阳面。如果栽树不注意阴阳面。改变了树木原来的生长方向,使向阳面栽成了向阴面,一时适应不了光
We know that the differentiation of plant tissue and the sun are closely related. Because of long-term sunlight and abundant ecological conditions, the foliage and the palisade tissue of the sunny side are more developed, the number of stomata is larger, the cell volume is smaller, and photosynthesis and transpiration are stronger. The shadows are weak, the temperature is low, the humidity is high, and the trees are different in structure and characteristics from the sunny side in order to adapt to their environment. This constitutes a tree in different directions of the structure and physical and chemical differences, the tree itself formed a yin and yang. If the trees do not pay attention to Yin and Yang. Change the original growth direction of the trees, so that the sunny side planted into the shade, and sometimes can not adapt to the light
