Spring is coming, many vegetables need to be seeded and seeded, so how do the eggplants graft in the spring? What are the management points after grafting and breeding? Let's learn about the spring grafting technique of eggplant together with the small series of Huinong. First, preparation before grafting It is recommended to use Torumbaum for the rootstock of eggplant, and the scion to choose the more popular varieties in the region, such as Shuoyuan Heibao and Jingjiao No.1. The rootstock was planted about 30 days earlier than the scion, and the seedling age of the spring aubergine eggplant was 60 days, and the 4 leaves and 1 heart were grafted. The rootstock and scion are watered one day before grafting. Second, the grafting method Eggplant grafting is generally carried out by a beveled method. When grafting, rootstocks and scions with uniform size and uniform stem size should be selected. The grafting site should be selected 6-10 cm high in the rootstock. (The grafting site is too high and the seedlings are unstable. If the grafting site is too low, the incision is easily buried by the soil layer when planting. Loss of the meaning of grafting). The first is to cut the rootstock and use a blade to cut obliquely from top to bottom at an angle of 30-45° (incision 0.5-1cm); secondly, cut the scion, and the scion leaves a leaf and cut into a 30-45 matching with the rootstock. ° Bevel (incision 0.5-1cm). The cutting rootstock and the scion face should be flush, once formed, and closely matched, and fixed with special clips. After the grafting is completed, avoid watering and infect the wound. Third, strengthen post-graft management 1. Warm light management The first three days after grafting, the light intensity is controlled, the sun is shaded, and the rainy weather reduces the sunshade, ensuring that the grafted seedlings in the arch shed can see about 20% of the light, the temperature is 25-28 °C during the day and 15-18 °C during the night. On the fourth day after grafting, gradually ventilate and see the light, increase the temperature difference between day and night. In the rainy weather, pay more attention to the ventilation and air release of the small arch shed to prevent the air in the arch shed from stagnation, which is not conducive to the survival of the grafted seedlings. 2. Fertilizer management Generally 7-8 days, after the grafted seedlings are no longer wilting, they are transferred to normal fertilizer management. Depending on the weather, you can pour the fertilizer water in 5-7 days, and choose high-quality fertilizer such as Baolifeng. The concentration is preferably 0.8‰-1‰. Properly control the moisture, prevent the lengthening, and cultivate strong seedlings. 3. Pest control Improve the growth environment of grafted seedlings and the combination of regular spraying, generally take 1-2 times to prevent the fungal diseases. 4. Refining and emergence The grafted seedling grafting interface heals well, and the plant grows to 4-5 true leaves. The plants are robust and can emerge. Spray the broad-spectrum fungicide carefully before emergence. The seedlings are started 5-7 days before planting, so that the seedlings can adapt to the colonization environment and slow down the seedlings as soon as possible. The main measures are: lowering the temperature, controlling the watering, increasing the amount of air released, increasing the gap of the seedling disk, increasing the illumination time and intensity. The above is the spring grafting technology of eggplant, welcome the farmers to come to Huinong.com to learn about agricultural planting techniques!
