1. Pull branches and open corners. Pruning by pulling branches and opening angles is to adjust the redundant paper strips in the tree by pulling branches to make them evenly distributed, increase space and improve ventilation and light transmission conditions. Pulling branches and opening angles is conducive to flower bud differentiation and early fruiting. Branching is usually carried out in the first half of June, when the growth of spring shoots slows down or stops. For the branches that are too vigorous and upright, it is an important measure to prune pear trees in summer by pulling and dropping branches to ease their growth potential, promote flower buds and bear fruit early.

2. Thinning branches and smearing buds. Thinning and budding refers to cutting off the over-dense paper strips from the base during the growing season. Pear trees have high germination rate and weak branch forming ability, and most of the crowns are sparse, so it is necessary to keep more branches and sparse them. It is very beneficial to early fruiting to use the method of pulling branches and opening angles to slow down the growth of long-growing branches and using the method of retracting and pruning more.

3. Pick your heart. Picking refers to the removal of 1~2 leaves from the top when the new shoots grow to a certain length. Tapping at different stages will have different effects. For example, for young trees with vigorous growth, tapping at the end of May to the beginning of June when the new shoots grow to 3-4 cm can promote the growth of the secondary shoots, accelerate the shaping, reduce the pruning amount, ease the tree vigor and lay the foundation for early fruiting. However, in August, pinching before the new shoots stop growing can promote the full development of new shoots and is conducive to safe overwintering. In order to promote new shoots to germinate secondary branches as soon as possible, 1~2 leaves under the wound can be removed while the new shoots are coring, so that axillary buds can germinate quickly and secondary branches can be quickly produced.

4. Adjust the branch angle. The branches of pear trees are upright and brittle, and it is not easy to open. After the full fruit period, the bones are open and the branches are prone to droop. The crown of young trees of most pear varieties is conical, which affects early flowering and fruiting, so it is necessary to open the main branch angle as soon as possible. However, due to the strong dryness and large opening angle of pear trees, it is easy to concentrate the growth advantage on the middle trunk, which weakens the growth potential of the extended branches. Therefore, the angle of the main branches of pear trees should be smaller than that of apple trees, generally requiring that the angle of the main branches should be between 45 and 55, and the maximum should not exceed 6. The methods of opening angle mainly include pulling, supporting, falling and tying. With the increase of tree age and yield year by year, the crown gradually opens. At the late stage of full fruit, the angle of the main branch increases, and its apex is easy to sag, and it needs to be retracted and trimmed too high.
