The invention discloses a soilless cultivation and seedling raising method for panicled fameflower. The soilless cultivation and seedling raising method for the panicled fameflower includes the following steps of 1 cutting processing, 2 nutritional pot preparation, 3 cutting management and 4 transplanting cultivation. The soilless cultivation and seedling raising method for the panicled fameflower simply and efficiently performs cutting propagation without transplanting cultivation, the survival time is shortened to be 3-4 days, a seedling raising period is short, the survival rate is 95-97%, the panicled fameflower is strong in resistance, vigorously grow and have thick and strong stems, lodging resistance and expanded roots, and edible parts are increased. Rooting liquid contains rich small molecules, is safe, non-toxic and high in utilization and absorption rate and promotes rooting. A cultivation matrix makes the panicled fameflower grow in a fixed mode, can absorb harmful substances in the process of adsorption and growth, is antibacterial and disinfectant, water-retaining, air-permeable, balanced in nutrition and high in absorption efficiency and controls sustained release of a fertilizer, and the planting cost is saved. Pesticides are not needed in the whole process, the soilless cultivation and seedling raising method is safe and environmentally friendly, does not cause pesticide residues and improves the panicled fameflower.
