Cherry tree belongs to Rosaceae, Prunus, and is a deciduous tree or shrub. Cherry is also known as cherry, Han Tao, Niu Tao, Zhu Ying, wheat cherry, wax cherry and cliff honey.

Prunus of Rosaceae is a small deciduous tree with a height of 8 meters.

Extended data:

Cherry leaves are ovoid to ovoid, 7~ 12cm long, sharp at the top, round at the base, with serrated edges of different sizes, glands between teeth, hairless or hairless at the top and sparse at the back.

The flowers are white, with a diameter of about 1.5~2.5cm, and the calyx tube is hairy; 3~6 clusters form racemes. The fruit is nearly spherical, with a diameter of 1~ 1.5cm, and is red. Flowering in March, flowering first and then growing leaves; Fruit ripens from May to June.

Pruning cherry trees:

First, pay attention to pruning. Cherry branches are divided into developmental branches and fruiting branches. There are many developing branches on young trees, the front leaf buds are elongated and grow, expanding the crown, and the lower axillary buds produce consequence branches. After entering the fruiting period, the terminal buds of most annual branches are outside the leaf buds, and the axillary buds are mostly flower buds, which are called fruiting branches.

The anterograde branches are divided into long fruit branches (15 ~ 20cm), middle fruit branches (5 ~ 15cm), short fruit branches (about 5cm) and flower cluster fruit branches (1 ~ 2cm).

Judging from the consequences, the fruit-setting ability of long fruit branches is poor, generally around 40%; The consequences of intermediate fruit branches vary from species to species; Short fruit branches have high fruit setting rate and good fruit quality; The fruit branches of flower clusters are the secondary fruit branches of flourishing trees in full fruit period, and the fruit setting rate can reach about 80%.

Fruit has the best quality and long life, which can reach 10 ~ 20 years. Fruit branches and flower clusters are the basis of yield composition. In China cherry and sour cherry, the proportion of long fruit branches and middle fruit branches is large in the early fruiting stage, while in the full fruiting stage, the short fruit branches and flower cluster fruit branches are dominant.

Second, the pruning of young trees In order to promote the early consequences of young trees, on the basis of plastic surgery, the pruning level of all kinds of branches should be light, mainly based on temporary pinching. In order to control the vigorous growth of branches, increase branches and rapidly expand the crown.

Summer pruning time should be postponed until before germination to prevent dehydration and withering of the cut. In addition to the main branch, extension branch short cut and appropriate thinning of some over-dense, interspersed branches, other medium and small branches should be retained as much as possible.

Thirdly, the pruning of fruit trees often stops in the winter after fruit picking.

Thinning is used to remove the perennial branches that are too dense and strong and disturb the crown, stop the adjustment of crown structure and promote the formation of flower buds. When thinning the big branches, pay attention to the small and flat wounds to help heal as soon as possible. When thinning annual branches, you can first cut them above the axillary buds at the base, and then thinning them after the consequences are exposed.

When pruning in summer, attention should be paid to stop the proper retraction of 2 ~ 3-year-old branches of main branches and short fruit branches, so as to soothe the growth of nutrients and the formation of new fruit branches from time to time, and avoid the consequences of outward migration and baldness outside the crown.

Fourth, the secondary obligation of pruning aging trees is to renew and rejuvenate in time, and to form COVID-19 by using the long branches that grow vigorously.

If the main branch is healthy first and there is no consequence, it should be retracted in time. The life span of China cherry cryptobud is about 5 ~ 10 years. In order to retract and regenerate branches, it is best to have small branches that grow normally at the retraction position, which is less harmful to the tree.

After pruning, take back the overgrown branches, select the branches with suitable direction, position and growth, and cultivate new main branches and lateral branches. Too much should be thinned out, and the rest should be cut short to promote branching, and then slowly released to form a consequence branching group. When the big branches are replaced with new ones, they should also stop after picking the fruits, so as not to cause the wound to flow glue.
