摘要

Dwarfing was achieved using pruning methods with a bending effect (sectorial double pruning, delayed sectorial double pruning). These methods were improved further by the addition of a new component, epinastic bending, which provides oblique shootsfor pruning to upper buds without bending or tying, by means of pruning a vertical or near-vertical shoot to an outside bud. For a similar purpose, the balanced application of mechanical crown and root pruning (i.e. correlative mechanical fruit tree pruning) restores or improves the yield potential within a smaller, "dwarfed" crown volume. Recent experience and analyses indicate that its effect is more permanent than expected, due to the fundamental changes wrought in the trees. These methods reduce themanual labour requirements of bending to between a third and a sixth, while the number of working hours required for manual pruning is reduced by 50-200 h/ha annually.
