摘要
本文对金红苹果(GM256中间砧)4种树形的光分布及利用进行了研究。结果表明:3种矮化树形(小冠疏层形、自然开心形、自由纺锤形)的光照强度、比叶重、叶绿素含量高于乔化树,光照水平及光能利用情况明显优于乔化树。3种矮化树形中,小冠疏层形的光照水平最好,是生产上应采用的适宜树形。
The illumination distribution and light energy utilization of four tree forms in Jinghong apple were studied.Results showed:the intensity of illumination,specific leaf weight and chlorophl content of three dwarf tree form(Xiaoguanshuceng tree form,Zirankaixin tree form,Ziyoufangchui tree form)were more than those of vigorous tree;the illumination level and light energy utilization were better than those of vigorous tree.In the three dwarf tree form,the illumination level of Xiaoguanshuceng tree form was suitable to be used in produce.
