Provided is awater planting cutting rooting method for clematis. The method includesthe steps of preparation of cutting containers, preparation of water planting nutrient solution, selection and treatment of clematis cutting slips, water planting culture, post-cutting managementand hardening-seedling transplanting process, on the basis of a water planting technology,effects of a plant growth regulator on the cutting rooting of the clematis can increase the rooting rate of cutting;the conditions of water, temperature, light, air humidity and the like are controllable during the cutting propagation process, effects of the outer environment on plant propagation rate are reduced, cutting rooting rate is stable, plant growth status is good,the problem of seasonal restriction is overcome, the breeding cycle is shortened,the survival rate of the cutting is increased,the survival rate of the cutting slips is more than 85%, and the method is conducive to the factory production and promote applicationof clematis plants, and has good economic, social and ecological benefits.
