The use of grafting seedlings to cultivate eggplant can not only avoid soil-borne diseases, but also effectively prevent the occurrence of diseases such as verticillium wilt and bacterial wilt in eggplant. Moreover, due to the developed rootstock of rootstocks, strong drought resistance, strong growth, and eggplant yield and quality Are higher.

The stocks with better rootstock varieties include red eggplant, Xingjin No. 1 and Xingjin No. 2 eggplant varieties. It is also possible to use tomato 802 and other varieties as stock. The use of this species as a wood graft, the plant's ability to withstand low temperature significantly enhanced, suitable for winter transplanting.

Grafting method 1 Walling method: When the rootstock and scion have 5 to 6 true leaves, grafting is best. When grafting, leaves a large and strong real leaves on the rootstock with poor development and can leave 2 true leaves, remove the rest of the true leaves, and then cut the stem with 0.5 to 0.6 cm scion with a blade to cut off the cotyledons And the upper part of a true leaf, the stem cut into a wedge-shaped, oblique 0.4-0.5 cm long, embedded in stock, with a grafting clip fixed seedling spacing 15 cm 15 cm. 1 by the connection method: When the rootstock seedlings grow to 2.5 to 3 true when the scion seedlings have 2.5 true leaves when grafting the most appropriate. The two seedlings with the same thickness were selected from the 1st to the 2nd true leaves with a beveled incision with a length of 0.4-0.5 cm, and the deep stem half of the rootstock was cut diagonally and cut upwards. Then, the interface is fixed with a grafting clip and contained in the nutrient cartridge. 3 Plugging: When the rootstock seedlings grow to 2.5 to 3 pieces, and the scion seedlings have 1 to 2 true leaves, the rootstocks are picked up and rooted. Try to bring as much leaves as possible to leave 1 true leaf. Remove the rest. A slightly inclined hole with a bamboo stem is used, which is about 3 mm deep, and then gently knifed along the lower part of the cotyledon of the scion to form a 2.5 mm long wedge-shaped incision. Insert the scion incision downwards into the small hole of the rootstock, and put it in the seedbed or nutrient bowl, shading, moisturizing and heat preservation. No matter what kind of grafting method is used for seedling management, the grafted good seedling should be placed in the seedbed after grafting. With a small arch shed, the relative air temperature in the shed should reach 90% to 95%, and the temperature should be maintained at 27 to 30°C. In this way, 24 hours after grafting, the callus will be generated, and it will survive 5 to 7 days. Temperature during the seedling period can not be lower than 20 °C, the initial shade should be appropriate, gradually see the light after 3 days, 5 to 7 days after the seedlings survive. Manage it.
