Cuttage and rapid propagation method for camellias

Abstract

The invention relates to a cuttage and rapid propagation method for camellias. The implementation of the method includes the following concrete steps that (1), a cuttage bed with perlite as a matrix is built; (2), a humidity control system and an automatic spray system are built, and according to the humidity changing condition on the surface of the matrix, spray equipment is controlled to provide and adjust the rooting and growing environment for cuttings; (3), robust annual or one-year-old branches above half lignifications and free from plant diseases and insect pests are selected as cuttings, and shearing and cuttage are carried out on the cuttings in time; (4), before cuttage is carried out, the cuttings are treated with a rooting agent to promote rooting; (5), after cuttage is carried out, the spray facility is started, humidity parameters are set, the spray time is adjusted after 40 days, seedlings can be lifted and put in flowerpots 60 days after cottage, and the seedlings are transplanted 15 days after seedling hardening. According to the cuttage and rapid propagation method for the camellias, the nursery stock propagation cycle is short, the investment cost is low, and the cuttage and rapid propagation method can be widely used for large-scale and industrial garden and park nursery stock development by individuals and enterprises.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for rapid propagation of camellia cuttings. Background technique [0002] Camellia is an important landscaping tree species that is difficult to survive from cuttings. In terms of breeding and raising seedlings, conventional field cuttings are often limited by factors such as season, environment and cutting operation process, and there is still a lot of room for improvement in important indicators such as rooting rate, survival rate, root system number, and reproductive cycle. There is also a method of grafting seedlings in production, but the trunk of the camellia seedlings is relatively thin, and the seedlings born in the current year cannot be used as rootstocks. It takes years of cultivation to reach the appropriate thickness. In addition, the new shoots of the 1-year-old camellia are not strong enough. , It needs to be cultivated for about 2 years b...

AI Technical Summary

Problems solved by technology

However, this technology also has some shortcomings in production. For example, its investment scale is large, and only the control system needs about 80,000 yuan; the temperature and humidity sensor is a highly sensitive electronic device, and the unit price is more than 10,000 yuan. It is easily damaged and has a short service life, so it is difficult to purchase matching replacement products in the market

Because of this, the key components of this technology need to be improved or replaced urgently, otherwise, it will be difficult to meet the market's requirements for seedling cultivation with low cost, easy operation and fast reproduction speed

[0004] For some precious fine varieties of camellia, due to the scarcity of resources and slow reproduction speed, the seedling cultivation period is long, the cost is high, and the difficulty of popularization and application increases.
