摘　　要：以10年生的红富士/M26苹果为材料,研究了改形修剪量对枝类构成及结果的影响.试验表明:随改形修剪量的加大,中长枝比例增加,产量减少,品质改善,成花增加,大小年减轻;但改形过重会引起树势明显反旺,品质下降,成花减少.适宜的改形修剪量应为总枝量的50%～60%.实行强拉枝和加强夏季管理是改形后必不可少的配套措施.The effect of different degree of pruning on constitute of shoot types and fruiting was conducted on 10 year-old Red Fuji apple trees on M. 26 interstock. The results showed that middle and long shoots was increased, the yield was decreased, fruit quality was improved, flower formation was increased, and trend of biennial bearing was decreased when pruning in modifying tree form was increased heavily. But when pruning was too heavy, it will stimulate tree growth more vigorously, fruit quality was decreased, and flowering were decreased. The suitable pruning in modifying tree form is cutting 50%~60% total shoots. Bending shoots heavily and exercising summer managements are necessary measurement after modifying tree form.
