| 摘 要： | 在渭北旱塬地区,以10年生乔化红富士苹果为材料,研究了不同时期摘心和扭梢对苹果背上枝生长及成花的影响。结果表明,适时摘心或扭梢均能极显著地控制背上枝生长,促进其成花;但摘心和扭梢过迟反而会促使2次枝生长,不利于成花,2次摘心效果不理想,过晚扭梢容易引起枝条枯死。综合比较,摘心和扭梢以5月中下旬最好,慎用2次摘心法,扭梢以使枝条呈水平状态更好。

| Abstract: | In Weibei rainfed highland,taking 10 years old Red Fuji apple as the material,we did research on influence of pinching and shoot twisting at warious stages on apples’ back branches and flowers growth.The results showed that: pinching and shoot twisting at proper time could control back branches growth and promoting its flowering significantly,but too late pinching and shoot twisting promoted the second branches growth instead,which was not good for flowering;unsatisfactory second pinching and too late shoot twisting,could easily cause the death of branches.Under comprehensive comparison,pinching and shoot twisting in late May were the best.Second pinching should be used carefully.Twisting shoots into horizontal status would be better. |
