对一年生枝条剪截时,剪口芽是具体操作首要考虑的对象,选择剪口芽时需要注意以下几点, 1、剪口距剪口芽的距离:距离过大,留桩部份容易干枯死亡,且不好愈合,也易感染病害影响剪口芽抽枝;距离过小易伤芽体,伤口干缩后也同样影响芽的萌发。正确合理的距离是:从芽的对面下剪,向芽尖倾斜,斜面上边高于芽尖1—2毫米,斜面下边稍高于芽基。剪口一定要平滑,伤面小,剪口芽生长健壮。 2、剪口的角度:不能顺着剪口芽的方向用剪,而应对着芽的方向,向芽尖倾斜20—30℃。剪口角度过 When the annual cuttings cut, cut mouth buds are the primary consideration of the specific operation of the object, select the cut mouth buds need to pay attention to the following points, 1, the cut away from the bud mouth distance: too much distance, leaving the pile part of the easy to dry Death, and poor healing, but also susceptible to infection affect the cut bud sprouting; distance is too small to hurt the bud, the wound shrinkage also affect bud germination. Correct and reasonable distance is: cut from the opposite side of the bud, tilted toward the bud tip, the upper edge of the incline 1-2 mm above the bud tip, the lower edge of the ramp slightly higher than bud base. Notch must be smooth, small wound, cut mouth buds grow robust. 2, Notch angle: You can not cut along the direction of the cut scissors, and deal with the direction of the bud, bud tip tilt 20-30 ℃. Notched angle too
