The winter pruning of cherry trees should not be premature, and it is advisable to delay it until it is near the bud. In order to control the growth of shoots, increase the amount of foliage, accelerate the expansion of the crown, and promote early fruition, the pruning of young trees during summer can be carried out after fruit harvesting, mainly by thinning, that is, removing excess dense and overgrown branches to adjust Tree structure, promote flower bud differentiation.

When saplings are pruned, it is appropriate to remove excessively dense and over-strength branches, to ease the middle and weak branches, and to promote the growth of leafy branches. During shoot growth, attention should be paid to picking the heart, controlling the growth, promoting branching and flowering. It is advisable to use natural open-hearted and plexiform natural forms. The plastic process should pay attention to maintaining the balance of the tree vigor. Attention should be paid to the cultivation of evacuation-type and uniaxially-extending branches on both sides of the backbone. After entering the full fruit period, the 2 to 3 year old shoots at the apex of the shoot and the fruiting shoots of the stem branch are moderately shrunken and sheared, so as to rejuvenate the result and control the position of the result to shift outward. Cherry saplings are mainly to establish a firm skeleton and culture result branches. After saplings planted for 1 year, after moderately short cutting, the shoots in the upper part of the shoots germinated as long branches, while the shoots in the middle and lower parts germinated as short and medium branches. Except for moderate lengthening, lengthening, and branching of the main branch extensions as required by plasticity, the mid-to-lower branches, except for dense, overlapping, and overlapping branches, are generally not thinned to increase the amount of foliage. . Early results.

After the cherries enter the full fruit period, the short-fruiting branches of the bouquet increase year by year, and the tree vigor weakens year by year. It responds to the 2-3 year-old shoots of short fruit-bearing branches, and timely retracts to strengthen the vegetative growth and promote the emergence of new fruiting branches. Prevent the relocation of the result area and control the height of the crown. For a vigorous annual branch, short cuts can be made to facilitate the formation of new fruit branches; annual branches of the moderately growing can be short cut; mixed branches can be cut at the 3 to 4 section before flower buds depending on the condition of flower buds. So that the upper branches, the lower part of the results.

After the cherry tree has entered the ageing period, attention should be paid to cultivating and using leggy shoots for tree crown renewal. When major branches are renewed, their wounds tend to gel, making them difficult to heal. Immediately after fruiting, the wounds heal quickly. And it is not easy to flow glue.
