A large number of grafting methods of peach trees How to graft peach trees

1. Peach tree planting can be divided into spring planting and autumn planting, in which spring planting is generally carried out after soil thawing and before germination, which is beneficial to delaying seedlings and will not cause freezing damage to seedling roots; Autumn planting is generally carried out after defoliation in autumn and before soil freezing, which is beneficial to early germination in spring. The best grafting time is mid-March in spring, followed by mid-early September in autumn. The glue is released too early and the survival rate is low too late. In production, more farmers like to graft in spring and summer, generally from February to April in spring and from May to August in summer, and the survival rate is relatively high.

2. The rootstock should be a peach seedling with strong growth, no pests and diseases, and a stem diameter of more than 0.5 cm. It has the characteristics of fast growth, and it grows very fast after grafting. The scion should choose new branches from peach trees, which have grown for more than 3 years. The seedlings on the surface of the branches should be smooth, tender, robust, free from pests and diseases, with full buds and uniform stem diameter. This is beneficial to the combination of cambium and improves the survival rate of grafting.

3. Prepare grafting tools, plastic bandages, knives, etc. There are many grafting methods in production, and bud grafting is commonly used. Select a bud eye on the rootstock, ring it with a knife at the upper and lower positions from xylem 1 cm, and then peel off the bark and bud eye together. Then cut a bud of the same size on the scion in the same way, align and press it into the peeled bud, closely fit it, and then tie it tightly with a plastic bandage.

4. Check every 7- 10 days after grafting, and wipe off the bud eyes of the rootstock mountain in time to concentrate nutrition and make the grafted buds grow vigorously. In addition, after the wound at the transplant site is healed, the plastic bandage can be removed to avoid overflow injury. After grafting, the plant grows vigorously and needs a lot of fertilizer. Fertilization should be timely, and foliar fertilizer mainly containing nitrogen fertilizer can be sprayed to promote the rapid growth of plants.
