1 主枝角度小,树势强旺,结果晚 采取措施:一般4～5年生枝开张基角,7～8年生枝开张腰角,主枝的基角在60°～70°,腰角70°～80°,梢角60°。同时开张侧枝角度,使其角度大于或低于主枝。开角时期一般为5月份或8月份,尤以秋季拉枝成花效果好。对辅养枝要拉平,促其结果,对竞争枝和旺长、徒长枝采取扭梢、摘
1 main branch angle is small, strong tree vigor, the results to take late measures: usually 4-5 years old branch opening corner, 7 to 8 years old branch opening waist, the main branch of the base angle 60 ° ~ 70 °, waist 70 ° ~ 80 °, the tip angle of 60 °. At the same time opened the side branches angle, the angle is greater or less than the main branch. Open-angle period is generally May or August, especially in autumn pull branches into a good effect. To raise the level of supporting the sticks, and promote the results of the competition branch and Wang Chang, the growth of the branches take twist tip, pick
