What does "heavy cut" mean?
Heavy pruning is mainly used when transplanting big trees. Because of the big tree transplanting, the root is severely damaged, if not the heavy cut, it will cause the root shoot ratio imbalance, moisture and nutrient deficiency will lead to severe late germination, vigor drops, and even cause death of trees. When transplanting big trees, the amount of pruning is usually about 1/2 of the total branches. If the root system is not big, the amount of the branches is about 1/3, the survival rate can be guaranteed.
Technical measures commonly used pruning: thinning (from base cut), short cut (cutting part of annual shoot), back (in parts cut, perennial) (not cut), put off buds, pinching, twisting shoots, pulls, with branches. In fruit tree pruning according to the growth of strength, flexibility and degree of pruning method. In general, moderate grower or partial Wang to light cut, due to heavy pruning trees weaker (by thinning, cutting and retracting method).
Short cut cut branches of 1 / 3 apex to 3 / 4 called short section. The purpose is to prevent the branches extend indefinitely, and promote cutting under the sprouting of axillary bud, which grow more branches, increase flower positions, the plant shape plump. In order to extend the crown of the canopy, the branches at all levels are distinct, and the cut should be located at the tip of a lateral bud.
