Pruning of plum trees is mainly in summer, supplemented by pruning in winter. Summer pruning is generally carried out from mid-June to early July, and it needs to be pruned 3-5 times in stages. The commonly used methods are pinching, twisting, girdling and taking branches. The second summer pruning is generally carried out after the fruit trees have fallen and thinned, and the third summer pruning is generally carried out after the plums have hardened.

Prune plum trees scientifically and reasonably to shape the tree shape, adjust the tree potential and coordinate the relationship between branches. Such pruning can realize the full supply of nutrients in each branch and ensure the high yield of fruit trees every year.

In addition, whether the pruning method of plum trees is in place directly determines the quantity and quality of fruits in the coming year. However, due to the different growth characteristics in different periods, the pruning methods are also different.

What are the pruning and shaping methods for plum trees?

Like other fruit trees, plum trees need pruning to set their shape at the young stage. Natural happiness and double-layer evacuation happiness are the two most commonly used pruning methods for plum trees.

Both methods have the advantages of simple shaping, convenient management, quick forming, early fruiting, high fruiting rate, long service life and good ventilation environment.

Generally, young plum trees can basically form a reasonable tree structure after 3-4 years of continuous pruning.

Optimum pruning time of plum tree

Pruning prunes can be done in spring, summer and autumn, but it is generally not recommended to prune prunes in spring, and attention should be paid to pruning in summer and winter, with summer pruning as the main factor and winter pruning as the supplement.

Pruning is usually carried out in sunny morning after dew on fruit trees is dried, which can reduce the risk of bleeding and infection with pests and diseases.

Pruning principle of plum tree

① Short fruit branches and bouquetlike short fruit branches are dominant.

Because plum trees mainly bear short fruit branches and bouquets of short fruit branches, pruning should be based on the basic principles of light cutting and long release and optimized ventilation and light transmission.

Focus on cutting off dense branches, competitive branches and flourishing branches on the back of fruit trees, and combine methods such as coring, taking branches and twisting for a while. In order to enhance the ventilation and light transmission environment of fruit trees and promote the better differentiation and formation of flower buds.

② Judging the pruning degree according to the growth stage.

Generally speaking, young trees and fruit trees in the early stage of fruiting should be mainly shaped and increased in yield. Give priority to perennial fruit trees and fruit trees in full fruit period, relax tree vigor, reduce ineffective consumption of nutrients and ensure high yield.

Pruning methods such as thinning, shrinking and pruning should be combined with the full fruit period and senescence period of fruit trees. Generally speaking, we should focus on retraction and rejuvenation, speed up the replacement of new and old branches, and cultivate new backbone branches and fruiting branches.

Through such pruning, plum trees can be restored to tree potential, new branches will grow as soon as possible, and normal fruit-bearing ability will be restored as soon as possible. So as to achieve the purposes of prolonging the harvest period and increasing the yield.

Pruning method of plum tree

① refinement

Thinning is generally to remove branches that grow too densely and branches that are not at the right angle to the base. This can reduce the obstruction of leafy trees to ventilation and light transmission, and reduce the consumption of nutrients by invalid branches.

Through thinning, the ventilation and light transmission environment of plum trees can be greatly improved, so that the key cultivation branches and each fruiting branch group can absorb more and more sufficient nutrients.

This pruning not only makes the fruit swell and develop better, the color is even, but also increases the later yield and improves the sugar content and taste quality of the fruit.

(2) Increasing year by year.

Thinning should be carried out year by year, and it is not allowed to pull out too many branches at a time, let alone too many perennial branches at a time.

Otherwise, it will not only reduce the branches and leaves of fruit trees, but also reduce the amount of nutrients synthesized by photosynthesis, making fruit trees malnourished and weak.

Moreover, if it is pruned at one time, it is easy to cause a large number of new shoots to sprout, and the fruit trees will grow white due to a large number of pruning, thus reducing the yield and quality of fruit trees.
