The invention discloses a planting method for obtaining good-quality and high-yield cortex moutan. The planting method for obtaining good-quality and high-yield cortex moutan comprises the steps of land selection, land preparation, seedling growing, timely transplanting, land management and the like. When base fertilizer is applied during land preparation, thoroughly decomposed farmyard manure and slow release nutrition particles are applied in a mixed mode, nutrition is comprehensive and balanced, the requirements for nutritional ingredients such as nitrogen, phosphorous, potassium, organic matter and microelements are met during seedling growing of moutan, the controlled release effect is good, the fertilizer efficiency is durable, the utilization rate is high, absorption is easy, the frequency of fertilizer application is reduced, and the emergence rate is increased; during sowing, seed dressing is conducted through modified plant ash, a good growing environment can be provided for growth of seeds, diseases and insect pests can be reduced, and the emergency rate can also be increased. By the adoption of the planting method, the quality of the cortex moutan can be improved, the yield of the cortex moutan can be increased, the cortex moutan can reach the high-quality level, the content of the effective constituent can be increased by over 10%, the yield is increased by over 35%, and the economic benefits of a moutan cortex farmer can be greatly increased; in addition, operation is simple, implementation is easy, cost is low, and the planting method is suitable for large-scale popularization.
