The growth and development of winter-spring quail eggplant must go through the winter and early-spring low-temperature stages. The grafted seedlings have strong resistance to low temperatures, developed roots and strong growth, and they advocate the use of grafted seedlings. The main methods of grafting are: A connection method This is a relatively common method used in the grafting of eggplant, with a high survival rate and high grafting efficiency. When the rootstock and scion eggplant seedlings grow to 5 to 6 true leaves, cut the upper part with a blade and cut the upper part of the rootstock, retain 2 to 3 true leaves, cut a 1 cm deep incision vertically in the middle of the rootstock stem, and then scion the seedling Unplug the eggplant seedlings between the purple and black stalk stems, remove the lower end, retain 3 to 4 true leaves, cut into wedges, the size of the wedge and the rootstock are equivalent, then the scion is inserted into the incision in the stock, aligned with a grafting clip it is good. Second, by the connection method Grafting was carried out when the rootstock and scion had 3 to 4 true leaves. The method is to select the rootstock incision between the second and third leaves, remove the leaves from the base, the incision from top to bottom, the angle of 30 to 40, take out the root of the scion, moisturize, with a blade in 3 to 4 At the true leaves, the leaves are cut off from the base, and incisions of about 1 cm in length are then cut upwards from the stem at 30 to 40 degrees, and then the two slopes of the rootstock and scions are relatively fixed with clips. Third, the plug method In the rootstock seedlings 5 ​​to 6 true leaves, scion 2 to 3 true leaves when the grafting. When grafting, the rootstock leaves 1-3 true leaves with a blade to cut off the upper part, and use a toothpick to tilt down a hole about 1 cm deep. Cut 6-8 mm wedge-shaped incisions under the shoots of the scions, and insert the scion incisions down into the holes in the rootstock.
