A kind of cutting propagation method of wintersweet

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for asexual propagation of plants. More specifically, the invention relates to a method for cutting and propagating wintersweet. Background technique [0002] Wintersweet, deciduous shrub, up to 4-5 meters high, often clustered, opposite leaves, papery, elliptic-ovate to ovate-lanceolate, apex acuminate, margin entire, buds with numerous imbricate scales, The leaves bloom first at the end of winter. The flowers are solitary in the leaf axils of the annual branches, with short stalks and cup-shaped receptacles. The perianth is arranged in a spiral shape, yellow and waxy. The flowering period is December-January, with a strong fragrance. There are many achenes and mature in June-July. There are solitary wintersweet and clustered wintersweet. The single stem has an obvious trunk and a certain height, while the clustered one is relatively short, about 3 to 3.5 ...

Problems solved by technology

[0007] 3. Hormone treatment: use 30-60ppm indole acetic acid and 30-60ppm naphthalene acetic acid mixed solution for treatment, the treatment time is 15-26 hours, the treatment time is long, the reproduction cycle is increased, the efficiency is low, the production operation is difficult, and it is not conducive to widespread to promote

[0008] 4. Substrate selection: choose a mixed medium of mountain mud, yellow sand, chaff ash, and charcoal. The matrix composition is complex and not easy to obtain, which is uneconomical

Due to the large changes in temperature and air humidity every day, only relying on manual control of environmental conditions is half the effort and the effect is not ideal.
