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...

Examples

Embodiment Construction

[0018] The test base is located in Baixiang Town, Yueyang County, Hunan Province. The transplanting bed and spray control system were built in August 2012. Two batches of cutting seedlings were implemented in mid-to-late August 2013 and early April 2014. The perlite, control devices and pipes used in this example are all from local building materials and electronics markets. The implementation steps are as follows:

[0019] (1) Preparation of slotting bed: build 3 slotting beds with perlite as the matrix, with a width of 1.4m, a length of 15m, and a matrix depth of 10cm. The specification of perlite is 14-20 mesh, a total of 9m 3 , totaling 2,700 yuan. Before cutting, spray 0.4% potassium permanganate solution or 400 times carbendazim to disinfect the bed matrix, operating tools and site, level the bed and compact the matrix, and spray water to saturate the matrix with water.

[0020] (2) Install the spray control system: set up the spray PE branch pipe along the direction o...
