Bud grafting propagation technique of peach blossom
Peach blossom is ornamental flowers, can be potted or planted in the courtyard, there are red and white flowers, sometimes red and white peach blossoms will open with the plant, attractive, in order to maintain these excellent qualities, more use of asexual reproduction method The survival rate of grafting in summer can reach 90% or more.
1. Scion selection
The peach blossom mother tree should be strong and free of diseases and insect pests, and the plants with excellent flowers and fruits should be selected as scions from the new shoots and strong branches of the current year and the full buds.
2. Grafting method
Summer bud grafting can be cut bud, or less with xylem bud, in the rootstock stem peeling, cutting the scion of the mother tree that is, cut off the leaves, leaving petioles. Cut upward at the position 1 cm below the scion bud with a knife tip, the length is 1.5~2 cm, the inner side of the bud should be slightly with xylem, the intermediate rootstock with bud can be selected as a pencil seedling, the stem is 3~5 cm away from the ground, the vertical part of the north side of the trunk is selected, the first knife slightly with xylem is vertically cut 2 cm, the bark cut off is 1/2~2/3, the bud is inserted into the rootstock, and the formation layer is closely connected, especially attention should be paid to leaving no gap at the lower part of the rootstock cutting position and tightly combining.

After budding 10~15 days, petiole yellow off, that is, the symbol of survival, petiole black is not alive. Surviving seedlings in the growth of new buds, healing completely after removing plastic tape, bud grafting in the above 1 cm cut stock. After germination, the rootstock should be removed and germinated. At the same time, fertilizer should be applied. Compound fertilizer should be applied 1~2 times to promote lignification of scion shoots and cold resistance. To control aphids, dimethoate solution can be sprayed. When leaf shrinkage occurs, a mixture of sulfur and stone can be used.
