摘要
光照对日本栗树结实具有重要影响。通过分析树冠的日射量和雌花的受光量对日本栗树结实的影响,找出影响原因及所带来的后果,提出在实际生产中要重视整形修剪工作,应通过整形修剪保持合理的树冠间隔,并采用合理的树形和保留合理的结果母枝量,以改善日本栗树的采光,进而达到优质高产的目的。
The effect of light on shoot growth, fruiting and physiological fruit drop of chestnut（Castanea crenata Sieb. Et Zucc.） was studied. The study showed that if the light amount received by the chestnut tree crown was sufficient, the fruit branch base diameter was big and most of the fruit branches fruited. Within lOdays of female flower blooming, if the tree crown received sufficient sunlight, the amount of physiological fruit drop decreased. The chestnut tree crown received 25-30% sunlight with suitable pruning was a precondition for chestnut best yield.
