Technology of Tomato grafting eggplant

With the development of facility agriculture, eggplant can be planted year after year, so soil-borne diseases such as eggplant Verticillium wilt have become the main obstacles affecting eggplant production. We used tomato (Maofan 802) as rootstock to graft eggplant, which not only effectively prevented eggplant Verticillium wilt and bacterial wilt, but also had tall and neat plants, good fruit quality and high yield. For eggplant grafting, we mainly use two methods: split grafting and leaning grafting. First, split grafting: generally, grafting is best when rootstocks and scions have 5-6 true leaves. Cut flat with a blade at the height of 3 cm of the rootstock, retain the lower 2-3 true leaves, remove the rest of the leaves, then use the blade to make a longitudinal cut 0.8-1.2 cm deep in the middle of the stem, pull out the grafted seedlings, leave 2-3 leaves at the top, cut them transversely, and cut them into a wedge, which is the same size as the cut of the rootstock, generally 0.7-1.1 cm, and then put the scion into the rootstock to make the graft consistent. When it is fixed with a grafting clip, the grafting is completed. It survived after about 10 days, with a survival rate of 90%. After the interface is completely healed, the clamp is removed and can be implanted in about 30 days. Second, leaning grafting: when the rootstock and scion grow to 2-3 true leaves. Cut obliquely between the first and second true leaves, cut the rootstock downward, cut the scion upward, cut about 0.5 cm, and fix the grafting clip. Third, grafting points for attention: first of all, the blades and clips used for grafting should be washed and disinfected, and the seedlings should be carefully taken and placed to keep them clean, do not touch the soil and do not wilt. Secondly, the grafting action is rapid, accurate and successful. Open-air grafting should be carried out after 4 o'clock in the afternoon in cloudy or sunny days, which can return seedlings quickly and have a high survival rate.
