Vegetable grafting cultivation has the advantages of improving the resistance of vegetable plants to soil-borne diseases, overcoming obstacles to vegetable continuous cropping, enhancing the resistance of vegetable plants to stress (cold, drought, high temperature), extending the harvest period, increasing yield, and reducing the amount of pesticides. Therefore, the vegetable grafting cultivation is popularized and applied everywhere, and the economic benefit is remarkable. However, the efficiency of vegetable grafting has always been low. For example, eggplants can be grafted with grafting clips. Each person can graft about 500 plants per day. The grafting efficiency is low and the labor cost of grafting is high. The use of special grafting catheter grafting can greatly improve the efficiency. The special catheter for grafting is colorless and transparent, non-toxic and tasteless, and has certain elasticity. There are four specifications of the inner diameter of the catheter, which are 2.5 mm, 2.8 mm, 3 mm and 3.5 mm, which are suitable for the grafting of seedlings of different sizes. When grafting, cut the catheter into 0.8-1.2 cm long segments. The advantage of the catheter grafting technology is that it significantly improves the grafting efficiency. Each person grafts more than 1,000 plants per day, and the grafting efficiency is doubled. At the same time, the catheter does not need to be removed after grafting, and it ruptures as the plant grows, simplifying the grafting operation procedure, and the graft survival rate is 95 Above 50%, the production cost of grafted seedlings per plant is reduced by 50%. Now take eggplant and tomato as examples to introduce the main technical points: Due to climate differences in different regions, it is necessary to conduct sowing date experiments to determine the appropriate sowing date. In general, eggplant rootstocks are sown 5 to 6 days earlier than the scion, and tomato rootstocks are sown 2 to 3 days earlier than the scion. Eggplant rootstock and scion begin to graft when 5 true leaves, tomato 2 to 4 true leaves begin to graft. When grafting, cut the stem tip of the rootstock with a blade at an angle of 30°～45°, retain one true leaf, and select a catheter with an appropriate inner diameter to cover the rootstock. Use a blade to cut the tip of the scion stem at an angle of 20° to 45°, leaving 2 leaves and 1 heart. Insert the tip of the cut scion into the duct of the rootstock to ensure that the rootstock and scion cut surface closely match. After grafting, the grafted seedlings are shaded and moisturized, and the temperature is controlled at 20°C to 25°C. Check the temperature and humidity in the grafted seedling shed every day, and start to see the light after 5 to 7 days. After the graft survives, daily management of the grafted seedlings is carried out in accordance with the routine. Note: Pay attention to adjust the sowing date and growth status of the rootstock and scion varieties, so that the stems of the rootstock and scion seedlings have the same size to facilitate the grafting of the duct. This technology is suitable for the eggplant and tomato production areas in the country. Disclaimer: Some articles of this website are transferred from the Internet.
