The invention belongs to the technical field of planting and particularly relates to a chimonanthus praecox cutting propagation method. The chimonanthus praecox cutting propagation method includes the following steps that firstly, cutting is conducted at the beginning of June, and a cutting medium is prepared 2 days before cutting and disinfected; secondly, a chimonanthus praecox tender branch is obtained, the upper portion of the branch is cut into a shoot for cutting, a lower notch of the shoot for cutting is in a horseshoe shape, and the shoot for cutting is steeped and disinfected after cutting is conducted; thirdly, 1-2 cm of the lower portion of the shoot for cutting obtained in the second step dips in an indolebutyric acid solution of 1500-2500 mg / Kg for 8-12 seconds and then is cut into the medium in the step A to be fixed, wherein the indolebutyric acid solution is prepared by ethyl alcohol with the volume percentage of 50 percent; fourthly, disinfecting is conducted each week, the relative humidity on the periphery of the cut shoot for cutting is controlled to be 85-95 percent in a spraying mode, the environment temperature does not exceed 40 DEG C until a lateral root grows out, and a cutting seedling is obtained and transplanted. According to the chimonanthus praecox cutting propagation method, the survival rate is high and can reach 85 percent to the maximum, the ornamental value and rapid propagation of chimonanthus praecox varieties can be easily kept, segregation of characters cannot happen, and the method has the quite good industry application prospect.
