[Edit this paragraph] Morphological characteristics
Small deciduous trees, up to 8 meters high, generally controlled at 3-4 meters after shaping, with reddish brown branchlets and no hair; The leaves are elliptic-lanceolate, 7- 15 cm long, and the apex is acuminate. Single or two axillary flowers, double pink. Other varieties are white, crimson, and sprinkled with gold (variegated).
[Edit this paragraph] Ecological habits
Liking light and drought requires fertile soil and good drainage system. It is necessary to strengthen management, fertilization, irrigation, weeding and pest control during the growing period. Cold tolerance is not as good as peach.
[Edit this paragraph] Distribution of origin
Originally from China, it is distributed in northwest, north, east and southwest China. Now all countries in the world have introduced and cultivated them. ?
Double pink flower. Drupe is spherical with short hairs on the epidermis. The flowering period is April-May.
[Edit this paragraph] Breeding
In order to maintain good quality, it is necessary to propagate by grafting, and the rootstock is plum blossom. Using summer bud grafting technology, the grafting survival rate can reach above 90%. The specific operation is as follows:
1, scion selection. The mother tree of peach should be strong and free from pests and diseases, and plants with excellent flowers and fruits should be selected as scions.
2. Grafting method. In summer, buds can be cut off, or xylem buds can be taken less and peeled at the stem of rootstock. Cutting the scion of the mother tree means cutting off the leaves and leaving the petiole. Cut the scion bud below 1cm, with the length of 1.5-2cm, and the inside of the bud should have a little xylem. The rootstock with a bud in the middle of the scion can be a pencil-thick seedling. The trunk is 3-5cm above the ground, and the vertical part on the north side of the trunk is selected. The first cut is the xylem, and the cut bark is 1cm. Wrap the grafted bud with plastic tape twice to the left and twice to the right, and tie it evenly, so as to prevent the bud from firmly combining with the stem and exposing the grafted bud. Pay attention to the budding time, the best is from June to mid-July in the south and from July to mid-August in the north.
3. Post-management. After bud grafting 10 ~ 15 days, the petiole falls off in yellow, which is a symbol of survival, while the petiole turns black, which means it is not alive. After the surviving seedlings grow new buds and completely heal, remove the plastic tape and cut off the rootstock above the budding point 1 cm. After germination, the rootstock is erased and germinated. At the same time, combined with fertilization, compound fertilizer is generally applied 1-2 times, which promotes the lignification of scions and has cold resistance. In order to control aphids, spray 2000 times dimethoate solution, and when the leaves shrink, use stone sulfur mixture.

Peach blossoms are colorful and enchanting. They are suitable for the layout of lakes, streams, roads and parks. They are also suitable for small courtyards and potted plants. They are also often used to cut flowers and make bonsai. There are also common peaches.
