What fruit can be grafted on the cherry tree? How to graft?

apricot, peach, plum, apricot, plum, cherry, loquat, etc. are all acceptable. Cherry belongs to Rosaceae, as long as all Rosaceae plants can be successfully grafted with cherry, Rosaceae plants have the following special symptoms: the receptacle is convex to concave; Flowers 5 cardinal numbers, arranged in a wheel shape; Perianth and stamens often combine to form a tube; Ovary superior, less inferior; The seed has no endosperm.

The grafting methods are as follows:

1. Grafting in spring (around the vernal equinox), and the suitable grafting time is about 15 days. Methods Shuttle bud grafting and split grafting can be used, and seedlings grafted in spring can leave the nursery in the same year.

2. Grafting in autumn (it takes about one month from summer to autumnal equinox). Generally speaking, the plate strip budding method can be used. Why do you want to graft in spring and autumn? Because there is a callus process after grafting, which requires external factors such as temperature, humidity and light. If the temperature is too high, more than 28 degrees or too low, less than 15 degrees, the man-made injury can not heal itself, and the self-healing process can not be completed, which will lead to low grafting survival rate.

Most of the grafts that don't survive are not self-healing, and too high soil water content will also affect the grafting survival rate. Therefore, it is not beneficial to irrigation during grafting, and the best water content of soil during grafting is about 16%. The moisture content should not be too low. If it is too dry, you can irrigate before, and stop grafting for 7 to 1 days. Remember, don't irrigate for 15 days after grafting. According to practice, the survival rate of grafting seedlings in the direct direction of strong light is lower than that in the shade. That is to say, it is best to avoid direct sunlight and graft in the direction facing away from the sun.

Extended information:

1. Bud grafting

(1) Suitable bud grafting. The suitable time for bud grafting can be divided into prophase and anaphase. The early stage is within l 5-24 days in the middle and late stage of 3; The later period is from the end of July to August, and sometimes it can last until the middle of September for 5 days. Grafting is too early, the scion is tender, the cortex is thin, and the bud development is not full; Grafting is too late. Most branches have stopped growing, and the grafted buds are not easy to peel off.

(2) Selection of ear and bud. When budding at different times, it is necessary to select the bud grafting and bud grafting differently. When grafting sweet cherry seedlings in the early stage and managing them after grafting, 5-6 full buds in the middle of strong branches should be selected as bud grafting. In the later stage of bud grafting, the buds on the strong scion can be used as grafting buds except the bud on the stem and the bud on the autumn shoot. For bud grafting in September, the full buds should be selected from the long branches in the crown of the tree.

(3) Cutting the grafted buds. When budding, the budding is first cut from the grafting secret. The bud piece of the grafted bud is large, about 25 cm long and about 1 cm wide. So as to increase the contact surface between the rootstock and the bud cambium and improve the survival rate. The bud piece of grafted bud is too small to survive; Even if the rootstock and bud heal and survive, the grafted bud is easy to burst and tilt, or grow poorly or even die.

(4) grafting and binding. After cutting the grafted buds, cut a knife in the vicinity of the ground, about 1 cm long. Shenda xylem. Then cut a knife vertically downward from the center of the horizontal knife mouth, 2.5 cm long and up to the xylem. When inserting buds, gently peel off the left and right cortex from top to bottom with the tip of a knife. Then the grafted buds are gently embedded in the cortex of the human rootstock. Do not push hard into the stock, so as to avoid rubbing the cortex of the bud or rootstock, causing glue flow and affecting survival. Finally, tightly bind it with a polyethylene film strip about t cm wide. After budding. It can heal after half a month and can be untied after 2 days. The survival rate is above 8%.

2. Plate budding

(1) The thickness of the rootstock for grafting in the second scion should be more than d.1 cm, and the scion should be collected! Annual branches, choose full buds as grafting buds.

(2) Cutting the scion When cutting the scion, cut the knife 1.5 cm below the scion, and gently cut the bud piece from the scion to form a length of 2.5 cm. Oval buds with a thickness of-2 mm.

(3) When grafting carefully. Choose a smooth part at the base of the rootstock 1 cm from the ground, and gently peel off a layer of skin along the vertical red direction. Form an oval-shaped sliced surface about 25 cm long and 1-2 mm deep (to expose the yellow-green cortex) and then. Stick the bud piece tightly on the cut surface of the rootstock and tie it tightly with plastic film tape.
