Pear 1 1 can be pruned from February to March, and 12-1 is the best pruning period. 1. In the first year of pear tree, measures such as light pruning, thinning branches, cutting buds, spreading auxin, girdling and opening angles were taken to promote the growth of branches, increase the amount of branches and leaves, and rapidly expand the crown. Because most pear trees have strong germination ability, but weak branching ability, it is easy to form more short branches by pulling, topping, dropping branches, taking branches and opening branches with various angle openers. 2. In addition, the short branches of pear stopped growing early and the leaf curtain formed early. After opening, the ventilation and light transmission are good, and the terminal buds of short branches are easy to form flower buds, realizing early high yield. Pear branches are easy to form an "included angle", which is brittle and easy to crack. When the branches grow to a certain thickness, it is difficult to open the corners again. Therefore, the opening angle should be carried out in time. 3. In the young stage of pear tree pruning, we must consider choosing suitable branches as the main branches, which is very important for the later growth. The principle of pruning other branches is to cut less and leave more. In the first year, six to eight buds usually stay on the growing branches.

Pruning techniques of pear trees in the first year

Branches need to be cut short, and the fixed trunk should be cut as short as possible when it is full of buds. Generally, the height of stem is about 80cm, and dense branches, diseased branches, withered old branches, trailing branches or cross branches need pruning to reduce the consumption of nutrients. 165438+ 10 to February of the following year, robust branches and leaves, as well as diseased branches and weak branches should be cut off.

Matters needing attention in pruning pear trees in the first year

Pear trees need to be kept in a cool, ventilated and warm environment after pruning. Don't sprinkle it on the leaves, otherwise it will cause the leaves of plants to rot and even cause the plants to wither and die. Keep the soil slightly moist.
