以‘华栗3号’锥栗为试材,采用田间调查法系统研究了锥栗3种主要树形的枝类组成、冠层内相对光照强度、叶片质量、果实产量和品质等指标.结果表明,开心形树冠整体光照条件良好,各层光照分布均匀一致,无效光区比例最低（27.78%）,枝量主要集中在树冠中、上层,分别占全树的45.52%和36.04%;自然圆头形树冠光照相对较差,各层光照分布不均匀,无效光区比例最高（36.11%）,枝量主要集中在中、下层,分别占全树的34.96%和40.11%;3种树形的长、中、短枝的比例变化不大,均以短枝为主,短枝比例分别占73.06%（小冠疏层形）、70.81%（自然圆头形）和66.47%（开心形）.开心形树冠上层的叶片比叶重最大值为15.77...

In order to explore the suitable tree and tree structure of Castanea henryi variety‘Huali 3'. TES-1335 digital illuminance meter and field survey method were used to study the following traits of three kinds of tree shapes: the branch composition,the relative light intensity in the canopy,the leaf quality,fruit yield and quality indicators. The results showed that: in open heart shape of tree,overall illumination condition was good,the distribution of light in each layer was uniform,and the ratio of the ineffective light area was the lowest (2...
