How does ornamental peach blossom and green peach reproduce? What are the pruning time and pruning methods? What are the main values?

Green peach is a variety of peach, which is relatively common in daily life. The ornamental nature of blue peach is very strong, and the double flowers are very beautiful and are loved by people. So do you know how to breed peaches? What are the pruning time and pruning methods? What are the main values?

First, how to reproduce the green peach

1. Methods of reproduction

In order to keep the quality of the peach variety, we often choose the grafting method to breed the peach.

2. Grafting method

When we use the grafting method to breed Bitao, we should first select a plant with good growth condition, and then use Shanmao peach as the rootstock. We usually carry out bud grafting or branch grafting in spring or summer. In this way, the survival rate of grafting can reach more than 90%. The wood buds should be cut first when budding in summer. Generally speaking, the suitable time for budding is from June to July in the south and from July to August in the north. Cut the scion of the mother tree, trim the branches and leaves, leave the petiole, and leave a little woody part on the inside of the bud. The stem is three to five centimeters from the ground, usually choose the vertical part of the north side of the tree, cut a suitable gap in the bark, closely fit the scion to the cut gap, and then wrap it with a rope to prevent the bud from drying.

3. Maintenance and management after grafting.

If the petiole of the scion turns yellow within half a month after budding, it indicates that the grafting is successful; if the petiole turns black, the plant did not survive. After confirming the survival of the scion, and after the scion and the rootstock are fully integrated, we need to cut the rootstock one centimeter above the place where the buds are grafted. Wipe off the anvil and sprout thoroughly after sprouting. At the same time, fertilizers should be applied to promote the Lignification of new buds, so that the successful grafted new seedlings have the ability to keep out the cold. After that, as long as you pay attention to the prevention and control of aphids.

2. Pruning time and pruning methods of Bi Peach

Pruning time:

The pruning of green peach during the growing period often varies according to the variety, tree age, tree potential and climatic conditions. The pruning time and times should be arranged according to the actual conditions of the cultivation site, generally around August after flowering, and can be pruned for 2 to 5 times.

Pruning method:

1. Wiping buds and removing sprouting means timely wiping off the long buds in the canopy, the buds on the back of the backbone branches, the competitive buds under the cut, and the buds on the upper part of the branches after flowering, so as to "remove and retain one" of the tender shoots, and the young trees will remove the strong shoots and leave the weak ones. Through this method, useless new buds and shoots can be reduced, nutrients can be saved, light can be improved, and the number of wounds caused by thinning branches during winter cutting can be reduced.

2. To pick the heart is to remove a small section of the twig at the top of the branch. Through coring, the lengthening and growth of the branches can be controlled and fuller flower buds can be formed in the lower part of the branches. In the early stage of shoot growth, coring can also promote the early germination of secondary shoots, which can differentiate fuller flower buds.

3. Twisting the tip means twisting the upper part of the unlignified and upright long branch by 180 °and tucking it into the lower half of the leaf armpit (pay attention to prevent it from warping up again). Through this method to change its growth direction, control growth, promote its transformation into flower and fruit branches, but also play a role in improving light.

4. The pull branch will be pulled out and fixed according to the angle required by the tree shape, and the most suitable opening angle is about 80 °. If the angle is not large, it is easy to appear the phenomenon of "upper strength and lower weakness", and it cannot be drawn into a bow, otherwise it will produce vigorous branches in the curved part. Through "pulling branches", we can ease the tree situation and prevent the phenomenon of "bare legs" in the lower part of the branches.

Generally speaking, the big branches of more than three years old can be carried out from May to September, and the main branches of young trees can not be opened until June to July. The pruning of green peach during the growing period often varies according to the variety, tree age, tree potential and climatic conditions. The pruning time and times should be arranged according to the actual conditions of the cultivation site, generally around August after flowering, and can be pruned for 2 to 5 times.

What are the main values of Bitao?

1. Gardens

The blue peach flower is big and colorful, it is beautiful when it blossoms, and the viewing period is as long as 15 days. In landscaping, it is widely used in lakeside, streams, both sides of roads and parks, etc., in small-scale greening projects such as courtyard greening embellishment, private gardens, etc., as well as potted ornamental plants, and often used to cut flowers and make bonsai. It is also common to weave branches and green peaches. The landscaping of Bitao has a wide range of uses, and the greening effect is outstanding, and the planting year has a particularly good effect. Can be planted, piece planting, isolated planting, there was a very good green effect in that year. Green peach is one of the commonly used color seedlings in landscaping, which is usually used together with purple leaf plum, purple leaf dwarf cherry and other seedlings.

2. Medicinal use

The gum secreted on the trunk of green peach, commonly known as peach gum, can be used as an adhesive and is a kind of glycan, which can be hydrolyzed into arabinose, galactose, xylose, rhamnose, glucuronic acid, etc., which can be eaten and used as medicine. it has the effect of breaking blood, promoting blood and tonifying qi.

3. Watch

The green peach blossoms with bright and beautiful colors, has a high ornamental value, and is easy to see in the park.

4. Bonsai production

The grafted peach seedlings will be cut from 1.5 cm to 2.0 cm above the bud before and after the next year to promote the growth of the bud, during which pot and shape pruning can be carried out at the same time. The sandy soil with loose ventilation, drainage and fertilizer preservation can be selected for Bitao soil. Pot matching should be pruned by purple sand pottery basin or glazed pottery basin whose color contrasts with flower color, and should be carried out gradually by means of pruning, twisting branches, pulling branches, bending, cutting, cutting, making marks, thinning flowers and so on, according to the tree potential and growth and their own aesthetics.
