The pear varieties cultivated in the past are generally tall in tree shape, thick and high in trunk, and can maintain a good tree shape only by removing dead branches. Now for the convenience of harvest management, the varieties that are not obvious in the dwarf trunk are vigorously promoted and planted. Therefore, it is necessary to cultivate a well-fixed tree to facilitate the management of growth. Then let's talk about how this pruning should be done and what shape is appropriate.

I. purpose of pruning

If the tree opening is not fixed stem leaves branches pruning, then nutrition transport can not reach the periphery, always difficult, external results are poor, loose so that the internal hollow, branches drooping, fruit can not receive good light and fall. The leaves and fruits too close to the ground are easy to accept excessive humidity, and the internal closure is easy to cause diseases. If the trunk is not shaded by the crown, it will sunburn and lose water, and die in severe cases. Rain and snow in winter can easily break branches and cause frostbite of tree trunks. Not pruning the crown is not beautiful, and it is inconvenient to manage.

2. Pruning method

Pear tree pruning is mainly for shaping and shaping, and there are two main pear tree shapes, mainly open stratification and multi-main branch natural shape. Each of the two kinds of trees has its own advantages and disadvantages, and it only depends on which aspect the growers value more. But the disease and insect branches, weak branches and over-dense branches are pruned like them.

1. Evacuation stratification type

First determine the trunk, generally the trunk should be about 1 meter from the ground, and then three strong lateral branches should be left in the germinating branches at one meter, and the three lateral branches should stagger and grow in the same direction. Then, all the leaves of the budding shoots on the trunk were subtracted, and three or four fruiting mother branches were left on the three side branches, and the rest were all thinned out. Finally, 5 to 7 fruiting branches were selected on the fruiting mother branch, and the rest of the weak branches were cut off. After the selection and retention of lateral branches, fruiting mother branches and fruiting mother branches, heart-picking should be carried out to avoid overgrowth and accumulate nutrients to promote the development of new branches.

two。 Natural shape of multiple main branches

Set the stem at half a meter of the trunk, but not too obviously, let it grow naturally after it is dried, then choose all the strong branches to stay and cut off the rest. A number of main branches are formed, and the tips of the main branches are only left as the fruiting mother branches, and the fruiting branches on the mother branches are also removed from the weak ones, so that they can be naturally pruned and maintained, but the remaining tips should also be pruned. In this way, the trim can be shaped.

The above are the technical methods of pear pruning, mainly around plastic surgery, but there are specific pruning and thinning, core removal, short rejuvenation and other detailed operation contents, together, withered pear trees are pruned according to their own reality.
