How can peach trees be grafted to survive easily?

The grafting time is spring or summer every year, because the temperature in spring and summer is just right. The period from mid-April to mid-June is most suitable for grafting, because the temperature difference between day and night is small during this period, which is very beneficial to the growth of fruit trees. Can promote the germination of branches. If you want to graft every day in summer, you can choose to graft in mid-August;

At this time, the juice of peach trees flows most frequently, and many branches are sprouting. If grafting is carried out at this time, the success rate is also very high. Dormant buds can be cut from the lower end of growing branches or sprouting branches as scions, and bud grafting can be carried out at a smooth place in the sunrise about 10 cm above the ground.

After two weeks, the joints were obviously swollen and some colloid was secreted. The budding eyes are green, which indicates that they have been grafted. After 2-3 days, the anvil stem was cut outward at 0.5 cm above the joint, and the incision was horseshoe-shaped to facilitate the rapid healing of the wound. When the new shoots grow to 6-8 cm, insert support columns at the edge of the rootstock, tie the new shoots and guide the new shoots to grow upwards. If it is found that there is no grafting survival, secondary grafting can be carried out in time.

Cultivation techniques:

Planting: The plant spacing is 4m×5m or 3m×4m, and 500-840 plants are planted per hectare. The planting period can be from defoliation to germination. Taoyuan cannot be continuously cropped, otherwise the young trees will obviously weaken, the leaves will lose their green color, the new roots will turn brown and the branches will flow with glue. This phenomenon is more serious in sandy soil or upper soil with low fertility.

Fertilization: the demand ratio of peach to nitrogen, phosphorus and potassium is about 1∶0. 5∶ 1. Young trees should pay attention to controlling the application of nitrogen fertilizer, otherwise it will easily lead to excessive growth. After the full fruit stage, nitrogen fertilizer was added to enhance the tree vigor. The content of potassium in peach fruit is 3. Twice as much as nitrogen. If potassium fertilizer is applied, the fruit will be large and the yield will be high. In addition, the peach garden should be cultivated regularly to weed, keep the soil loose, and drain water in time to prevent stagnant water from rotting roots.

Plastic surgery: make it more natural and happier. The height of the stem is about 60 cm, leaving 3-4 main branches, and the opening angle of the main branches is 50-60. Each main branch should have 65,438+0-2 auxiliary branches, and the branchlets on the main branch and auxiliary branches should be as few as possible. Pruning period includes winter pruning and summer pruning.
