Pruning helps to improve peach quality points for attention in summer pruning of peach trees

Summer pruning can assist the shaping of peach trees, inhibit the growth of new shoots, reduce nutrient consumption, improve ventilation and light transmission, promote flower bud differentiation, improve peach quality and yield. There are generally 3-5 summer clips in the whole year, mainly from May to August.

Peach tree

1. Erase buds: after peach trees sprout, remove dense buds, put buds on their backs, and put buds in an inappropriate position. When the new tip grows to 5-6 cm, wipe off the useless shoot. Leave a double tip with a large angle and erase the one with a small angle. The sprouts in the 15cm at the base of the backbone branches of the peach tree and the clustered new shoots of the sawing mouth should also be erased in time.

2. Heart-picking: there are many secondary shoots of peach trees, which will lead to more secondary shoots and closed crowns, so in peach cultivation, in addition to the plastic shaping of young trees, coring of extended branches of main and lateral branches is not recommended for peach trees.

3. Twisting: when the upright and vigorous shoot of the peach tree is 25-30cm long and semi-lignified, hold the base of the new shoot by hand and twist 180 degrees at 5-10cm, making it oblique or sagging. Twisting is generally carried out in May-June, and if the twisted branch emerges again, the twisting can be carried out again. Except for the non-twisting of elongated branches and their auxiliary shoots, the competitive branches of other elongated branches, the dorsal upper branches of backbone branches, the overgrown branches of inner bore branches and the vigorous long branches near large wounds can be twisted. Twisting can control the growth of peach branches, ease the tree potential, and transform the branches into full fruiting branches, which has the dual functions of fruiting and renewal.

4. Thinning branches: when the new shoots of peach trees reach 30cm, the quality and properties of peach branches can be judged according to the growth potential, thickness and position of peach trees, and the strong branches with suitable position can be selected to remove competitive branches, overgrown branches, thin and weak branches, dense branches, erect branches and drooping branches. After the fruit is harvested, some dense perennial branches, current year branches, and some vigorous branches on the back or outside are removed. After cutting and falling flowers, the fruit branches that have set fruit can be cut short in the upper part of the young fruit, and the medium-long fruit branches that have flowered but have not set fruit can be cut short by 2-4 buds, so that they can bear fruit branches in the same year. Before June, the overgrown branches germinated on the main and lateral backbone branches and inside the crown, if there is space, can leave 1-2 nodes at the base for ultra-short cutting, and cultivate small and medium-sized fruiting branches; if there is no space, it should be removed from the base.

5. Holding branch: also known as stripping branch, the new shoot with the characteristic of overgrowth on the 60 cm long side changes its growth direction by taking the branch, that is, holding the new shoot with four fingers, pressing the thumb down, and the four fingers moving down to the top at the same time, gradually moving from the base of the new shoot to the tip, injuring the xylem, hearing the sound but not breaking the branch. Taking branches can ease the branch potential, which is conducive to nutrition accumulation and flowering and fruiting, which is generally carried out from July to August.

6. drawing branches and top branches: drawing branches is the key measure to ease the tree potential, shape young trees, bear fruit early and prevent the lower part of peach branches from being bald. For the main and lateral branches with small opening angle and inappropriate extension orientation, or the erect large fruiting branch group, the opening angle or orientation can be adjusted by means of brace, pull, difference, fall and so on. The angle of pulling branches is generally about 80 °, which can not be pulled into a horizontal or drooping state; for the main and side branches of peach trees with excessive opening angle, the branches with branches can be used to reduce the angle, which is more than in August.
