Summer pruning of peach trees, also called growing season pruning, can generally be carried out from the time when the peach tree sprouts to when the branches stop growing. The reason why summer pruning is necessary is mainly because the buds on the new shoots of peach trees are precocious and can sprout and shoot multiple times a year. The new shoots are large and vigorous. The location where primary or secondary secondary shoots occur is often high, and the branches are densely packed, blocking wind and light. Most branch tips are often difficult to use rationally because they are far away from the backbone branches, resulting in excessive winter pruning and excessive nutrient loss. Therefore, it is generally necessary to prune about 1-4 times in summer.

For summer pruning of peach trees, the pruning purposes and pruning methods are different between different tree ages. Generally speaking, for young peach trees, pruning in summer is mainly to reduce the branches, control the growth, improve the utilization of nutrients, promote the growth of new shoots, overcome the weak top and bottom of the crown, balance the tree vigor, and utilize more With the characteristics of secondary shoots, the backbone branches can be selected and cultivated in advance to accelerate the expansion of the crown and form a high-yielding tree shape in advance.

For peach trees in the fruiting period, summer pruning is mainly to adjust the conflict between new shoots and between new shoots and fruits for nutrients and water, and to reduce the ineffective consumption of nutrients. Summer pruning improves ventilation and light transmission conditions in the canopy, improves leaf photosynthetic efficiency, and achieves the purpose of increasing fruit setting rate, improving fruit quality and increasing yield. It also promotes good differentiation of flower buds to ensure high yields in the coming year and successive years. Do peach trees planted that year need to be pruned in summer? To make peach trees bear fruit earlier, you need to prune them like this

Normally, peach tree pruning is mainly done in summer, supplemented by winter pruning, while peach trees in the fruiting period are pruned Winter pruning is the main method, and summer pruning is supplementary. Only by combining winter and summer pruning can the real pruning effect be achieved. When pruning in summer, it needs to be carried out multiple times. Generally, the first time is carried out from April to June. The purpose is to promote the growth of branches to form good nursery branches and fruit-bearing branches; the second time is from June to July. The purpose is to promote new growth in the inner tubes. The tissues of the shoots and peripheral auxiliary shoots are enriched and the flower buds are divided well, so as to improve the quality of the flower buds; for the third time, from July to September, the purpose is to remove all the main shoots and the tender tips of the auxiliary shoots to promote tissue enrichment and full flower buds for safe wintering. Be prepared.

For peach trees, we all know that whether they are young peach trees or peach trees in the fruiting period, they need to be pruned in summer. As peach tree seedlings that were just planted that year, can they be pruned in summer? In fact, not only summer pruning is required, but winter pruning is also required. If the peach trees planted that year are not pruned and allowed to grow, they can grow to a height of more than 2 meters, and the main stems will be thick, the secondary shoots will be thin, and there will be a lack of full buds. It will be difficult to set and shape the stems, and the survival rate after planting will be low. high problem. If pruned in summer, the above situation can be overcome, so that the main trunk is strong, the secondary shoots are fully developed, the buds are full, and the survival rate after planting is high.

How should pruning be carried out in summer for peach trees that were just planted that year? Generally speaking, after peach trees are planted, they must first be dried to a height of 60-70 cm. For peach seedlings with secondary shoots, 1-2 buds should be left at the base of the secondary shoots for short cutting. Summer pruning cannot be completed in one go. It also needs to be pruned multiple times. Specifically, the main tasks and purposes of each pruning are:

The first summer pruning mainly involves Wipe the buds after they sprout. Wipe off the buds below 30 cm from the ground on the trunk. After wiping the buds, keep 7-8 new shoots in the shaping tape. The main purpose of wiping the buds is to reduce nutrient consumption and centrally supply nutrients to the growth of new shoots in the shaping zone.

The second summer pruning time is probably from May to June. When the new shoots grow to about 30 cm, according to the requirements of the tree shape, select three or two new shoots with strong growth and suitable orientation as the main branches, and topping or twisting the remaining new shoots to control their growth and promote the main branches. The growth of branches. When twisting the shoot, twist it about 10 cm from the base of the new shoot, diagonally downward or horizontally.
