Method for cutting propagation of Camellia oleifera trees

Abstract

A method for cutting propagation of Camellia oleifera trees, comprises the following steps of (1) cutting treatment by cutting 5-7 cm of annual Camellia oleifera branches as cuttings, retaining 2-3 leaves on cuttings, and putting the cuttings in a 80-100 ppm GGR6 green plant growth regulator solution for 1-2 hours and then inserting into a culture medium; (2) shading treatment of the cutting seedlings; and (3) refining seedlings by carrying out refining treatment five to ten days after rooting, reducing the humidity in the greenhouse to 50 to 60% at first three to ten days of refining; removing the shading every morning and evening on the 4th to 7th day of refining and only shielding for four hours from 10:00 to 14:00, and completely removing the shielding on the 8th to 10th day of the refining. The culture medium used in the step (1) contains, in parts by weight, 100 parts of fermented Chinese medicine dregs, 30-50 parts of cinder, 20-40 parts of perlite, and 5-10 parts of water retaining agent. The method has the advantages of high survival rate of Camellia oleifera trees and improves seedling speed.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a cutting propagation method of camellia oleifera tree. Background technique [0002] Camellia oleifera, Latin name Camellia oleifera Abel, alias: tea seed tree, camellia oil tree, white flower tea; Camellia oleifera belongs to Theaceae, small evergreen tree. Because the seeds can be squeezed oil (tea oil) for food, so it is named, tea oil color is clear and fragrant, rich in nutrition, storage resistance, is a high-quality edible oil; it can also be used as lubricating oil, anti-rust oil for industry, tea cake is not only a pesticide , is also a fertilizer, which can improve the water storage capacity of farmland and control rice field pests. The peel is the raw material for extracting tannin. [0003] There are two methods of propagation of camellia oleifera: sexual reproduction and asexual reproduction. Among them, sexual reproduction will destroy the shape...
