摘　　要：为缓解贵阳市因光照强度偏弱影响甜樱桃生长的问题,从定植第2年定干整形时起对主枝间夹角作≤30°、45°、≥60°3种处理,在定植后的第5年对树体进行营养生长和初果情况的统计分析中发现:3种处理对应的营养生长量和结果树百分比随主枝间夹角增大而显著增加.主枝间夹角≤30°的植株.主干周长平均为14.54 cm,结果树仅有38.89%;45°处理的植株主干周长为14.1 cm,结果树占62.96%;而≥60°处理的植株达到15.22 cm和82.86%,三者之间存在显著或极显著差异.主干周长达到18～22 cm的植株结果树显著多于其它植株.The experiment was conducted to investigate the relation between main branch angle and stock circumference, primary fruit rate in sweet cherry. The results indicated that the vegetative growth and rate of fruit tree significantly increased with increase of main branch angle. The stock circumference and rate of fruit tree of three treatments with ≤30°, 45°and ≥60° were 14.54 cmand 38.89%, 14. 1 cm and 62.96%, and 15.22 cm and 82.86% respectively after planting 5 years and there was very significant difference or significant difference among three treatments.
