Cucumber grafting method

    First, the production point straight insertion method: use black seed pumpkin as a rootstock, choose a strong affinity, good quality, more resistant to the local varieties of the scion. The anvil and ear seeds need to be disinfected and germinated before sowing. When winter and spring sorghum are grafted, black seed squash should be sown for 2 to 3 days (with temperature control seedlings). To be seedling rootstock second true leaf buds, the first true leaf scion seedling 1 cm in diameter, is the best of grafting. The growth point of the rootstock was cut with a razor blade, and then bamboo needles (self-made, with the cotyledons of the scion) were inserted vertically from the incision 4 to 5 mm. The scion was cut at a distance of 30 ° from the hypocotyls at 5 mm below the cotyledonary node, and was an elliptical-shaped cut surface of 4 to 5 mm in length. Then remove the bamboo needle, insert the scion with the cotyledon into the pinhole, make the scion match the rootstock and fix it with a plastic clip. After spraying the water, put it in a moisturizing small arch shed. Maintain 95 % humidity within 3 days after the connection , daytime temperature 25 to 28 °C, nighttime 18 to 20 °C. After 4 days, it is small and ventilated. After 8 days, the film can be peeled and smelted. About 25 days into the three-leaf one heart period can be colonized.

    Second, the connection method: the rootstock in the nutrient bowl, on the hypocotyl of the ion leaf section 5 to 10 mm, obliquely cut from the top to the mouth of 6 to 10 mm, 20 to 30 mm under the coniferous cotyledonary node Bottom-up obliquely cut the mouth of 6 to 8 mm (without cutting the seedlings and rooting), then insert the scion tongue into the incision of the rootstock, fix the joint with a micro-plastic clamp, and bury the root of the scion with soil. The base of the scion was cut off in about 20 days, and other managements were basically the same as the straight insertion method. ( Li Suqiao )
