High-yield melon grafting seedling raising method

The invention discloses a high-yield melon grafting seedling raising method which comprises the following steps: preparation of a seedling raising substrate: spreading 40-50kg of organic nutrient fertilizer in every plot; seed treatment: soaking seeds with a copper sulfate solution, chitooligosaccharide, diethyl aminoethyl hexanoate, magnetized water, tea saponin, mushroom protein polysaccharides and Amobam; grafting: chamfering a rootstock caudex part into an inverted-V-shaped structure, inserting a tongue-shaped wedge into the cut of the rootstock, and performing fixing by using a grafting clamp; and grafted seedling treatment: immersing the grafted seedling in a mixed solution which is prepared by mixing a 17% fungicide Junchongqing solution and a 15% paclobutrazol solution and adding water for dilution, and meanwhile, performing fumigating treatment. By using the method, the nutrient and water supply to the substrate are balanced, the seedling rate reaches 90% or above, the seedling rate of the grafted se
