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。
In this paper, the light distribution and utilization of 4 tree species of golden apple (GM256) were studied. The results showed that light intensity, specific leaf weight and chlorophyll content of three dwarf trees (small sparsely populated, natural happy heart, free spindle) were significantly superior to those of Qiao and the light intensity and light energy utilization Qiao tree. Among the three kinds of dwarfed trees, the light level of sparsely populated small canopy is the best, which is suitable for tree production.
