The latest course of pear pruning techniques and methods

Pear varieties cultivated in the past generally have tall trees, thick and tall trunks, and can maintain a certain good tree shape by removing dead branches at ordinary times. Now in order to harvest management to facilitate the promotion of planting are dwarf trunk is not obvious varieties. So you need to cultivate a well-established tree to facilitate the management of growth. Then let's talk about how to do this pruning and what type is appropriate.

I. Purpose of pruning

If the branches are pruned, the nutrient transport does not reach the periphery, it is always difficult, the peripheral fruit is poor, the loose makes the interior hollow, the branches droop, and the fruit does not receive good light and falls. The leaves and fruits are too close to the ground to accept excessive humidity, and the internal canopy is easy to cause diseases. Without canopy shade, the trunk will burn, lose water and die in severe cases. Winter rain and snow fall pressure is easy to break branches, causing tree trunk frostbite. Not pruning the crown is not beautiful, management inconvenience.

II. Trimming method

Pear tree pruning is mainly for shaping and shaping, and there are two main pear tree shapes, mainly scattered hierarchical and multi-main branch natural shape. Each tree has its own advantages and disadvantages, depending on which aspect the growers value more. But the diseased branches, weak branches and over-dense branches are pruned as well.

1. evacuation layering

First determine the trunk, the general trunk should be about 1 meter away from the ground, and then in the germination of a meter of branches to leave three strong branches, three branches to stagger growth, not the same direction. Then all the sprouting branches and leaves on the trunk will be cut off, and three to four fruit mother branches will be left on the three lateral branches respectively, and the rest of the branches will be thinned out. Finally, 5 to 7 fruit branches will be selected on the fruit mother branches, and the rest will be completed after cutting off the weak branches. The lateral branches, fruiting mother branches and fruiting mother branches should be picked to avoid excessive growth and accumulate nutrients to promote new branches.

2. polychaete

Set the trunk at half a meter, but don't be too obvious. After setting the trunk, let it grow naturally. Then choose all the healthy branches to stay and cut off the rest. On the formation of a number of main branches, the branches on the main branches are also only strong to do fruit mother branches, the fruit branches on the mother branches are also removed weak, so natural pruning can be maintained, but the branches left should also be picked. This trim will set the shape.

The above is the pear pruning technology method, mainly around the shaping to carry out the operation, but there are specific pruning thin shoots, picking buds, short rejuvenation and other fine operation content, together, dry according to their own actual pear pruning.
