Pruning method for improving fruit bearing amount of olive trees

Abstract

The invention discloses a pruning method for improving the bearing amount of olive trees. The method comprises the following steps of: pruning in sapling age: in a year after the planting of the saplings, retaining a strong upright branch of each tree as the trunk and pruning the other branches, when the trees are 1-1.2m high, picking off the tips of the trunks and retaining 2-3 lateral branches as the main branches, and when the trees are 2.5-3m high, picking off the tips of the main branches and pruning the branches; pruning in full productive age: adjusting the proportion of the bearing branches to the nutritional branches according to the bearing amount; and pruning in rejuvenation age: carrying out heavily retractive pruning on the tree bodies or sawing all the branches from the trunks, wherein when the trees are 2.5-3m high and the tips of the main branches are picked off in the sapling pruning period, light pruning is carried out on the varieties which are early in blooming and bearing and heavy pruning is carried out on the varieties which are late in blooming and bearing. According to the pruning method provided by the invention, the olive trees can bloom and bear in advance and the yield of the olive trees can be greatly improved.
