Pear trees are a common fruit tree species in the orchard economic industry and are widely planted in China. Varieties such as Guan pear, Su pear, and Sha pear are very popular in the market. But no matter which variety it is, plastic pruning is an essential technical measure in its cultivation and management. So how to do pruning management of pear trees in summer? Let’s find out together.

Principles of summer pruning

1. Depends on the situation: Since summer pruning is to alleviate the potential of trees, promote flowering and increase fruit setting rate, it is generally only suitable for young trees, lush trees of trees, thick branches and thick branches, especially in dense orchards.

2. Different places: Since the growth potential of pear trees in different orchards is different, the phenological stages are different, and the pear trees of different ages are also different, corresponding summer pruning techniques should be adopted according to the tree, garden, ground and age.

3. The amount of pruning: The pruning amount of pear trees in summer is generally light. At present, winter pruning is the main method in various places, and summer pruning is supplemented. The two are combined and complement each other.

Summer shearing time

Summer shearing time should not be too early. When the growth of medium and short branches has basically stopped, the leaf area of ??the tree has reached more than 85% of the whole tree, and the new shoots are at a semi-lignification level, that is, it is best to carry out supplementary pruning on May 1 and mid-May, and from June to July.

Summer shearing methods

1. Ring carving

Ring carving is a method of ringing annuals with scissors at intervals of 30-50 cm before germination in spring. Method of shoot phloem. The purpose is to encourage the buds below the loop to grow into strong shoots, which can then be cultivated into medium or large fruiting shoot clusters.

2. Heart harvesting

During the growth stage of new shoots, the young tips at the tips should be removed. Heart harvesting can inhibit the growth of new shoots in a short period of time, reduce nutrient consumption, accumulate and promote the growth and enrichment of branches, and reduce overwintering pumping.

3. Sparse branches

Remove branches with scissors and saws, as well as vigorously growing new shoots on the back, top and indoors. Try not to pick heart-shaped or shorten growing and stopped growth. Various long, medium and short sprouts. No more than 1/3-1/2 of the back branches should be removed.

4. Pruning

Pruning is usually carried out on June 1 and mid-June. When the growth of spring shoots slows down or stops, the excessive and upright branches should be pulled out or dropped to slow down their growth, promote the development of flower buds, and achieve early fruiting. It is an important measure for summer pruning of pear trees.

5. Bending branches

From July to August, the newly grown branches will grow downward or left to right under the action of external force. You can also tie it to the branches of itself or other plants to change the direction of growth, or you can wrap the branches in a circle, but you must not break them.

In general, summer pruning of pear trees is of great significance to improving the yield and quality of pear trees. However, you must pay attention to the pruning principles of pear trees. Do not cut down blindly in summer, and learn to use the above methods flexibly.
