ask:
What is the grafting process of eggplant? What links do you need to pay attention to? When the rootstock stem is 3-5 mm thick and the scion grows to 5-7 true leaves, it is the best time to marry. The grafting site is generally on the section between the 2nd and 3rd true leaves of the rootstock, so pay special attention to the length and thickness of the rootstock section. Eggplant grafting is generally carried out by splicing. The splicing method is carried out when the rootstock seedlings have 5-6 true leaves. First, the rootstock seedlings are kept in two true leaves, and the stems and leaves of the above part are cut off at one time, and then a deep cut of 1-1.5 cm is cut downward from the center line of the stem at the incision. Subsequently, the scion is kept 1 leaf 1 heart, cut into a wedge shape with a slope of 1-1.5 cm (according to the cutting of the rootstock), and immediately inserted into the incision of the rootstock, so that the slits are aligned and tightly fixed with a grafting clip.
The operator's hand and grafting tool should be disinfected with alcohol or potassium permanganate solution several times during the grafting process to avoid cross infection of the bacteria. At the same time, it should be noted that the hands and blades should be in contact with the incision after drying, otherwise it is difficult to heal after the incision is wet or liquid. In the first 3 days after grafting, the relative humidity of the air should be kept at about 90% to promote healing between the rootstock and the scion as soon as possible. After 3 days, the temperature should be lowered in time to prevent the growth of the bacteria on the wound. When the humidity is insufficient during the healing period of the wound, the water cannot be sprayed directly, and the ground water supply can be used to increase the humidity. The temperature requires 23-26 ° C during the day and 17-20 ° C during the night. Generally 6-8 days, grafted eggplant can pass the graft healing period.
