Rapid propagation method for autumn single node cutting of tea-oil trees

Abstract

The invention relates to a rapid propagation method for autumn single node cutting of tea-oil trees. The method comprises the steps of building a rectangular piece of land for cutting, i.e., selecting a common rectangular piece of land, changing the soil layer locally, and replacing subsoil with underearth; selecting seedlings, i.e., selecting well-bred tea-oil parent tree branches with a branch length being 20 cm or over 20 cm and a stem diameter being 3 mm or over 3 mm; obtaining cuttings by cutting, i.e., cutting semi-lignified red-stem branches off to obtain the cuttings being 3-4 cm long and having one leaf and the cutting being 4-5 cm long and having two leaves by way of obliquely cutting the red-stem branches off; preparing an agent, i.e., pouring a rooting powder diluent into two treated containers, wherein the depth of the agent liquor poured into the containers reach 2-3 cm; dipping the cuttings, i.e., binding the cut cuttings into a small bundle in a certain quantity by way of aligning the lower cuts of the cuttings, dipping the small bundle in the containers with the rooting powder diluent, and dipping the small bundle for two hours and then taking the small bundle out; carrying out cottage on the cuttings, i.e., carrying out cottage on the dipped cuttings in the land for cutting according to a sequence of the cuttings with one leaf and the cuttings with two leaves; and hermetically covering the land, i.e., hermetically covering the land with a small arch shed thin film and covering the thin film with a sunshade net, wherein the shading degree of the sunshade net is 70%-80%.

Description

technical field [0001] The invention relates to a propagation method of camellia oleifera, in particular to a rapid propagation method of camellia oleifera cuttings with short ears in autumn. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Camellia oleifera (Camellia oleifera Abei.) belongs to the Camellia family Camellia genus. It has wide adaptability and strong resistance. It can grow well in the south of 33 degrees north latitude in my country. It is also the best woody oil crop in my country at present. Camellia oleifera has high oil content and good quality. The fat content of camellia seed kernels is as high as 50.1%. According to "Chinese Camellia Camellia" (China Forestry Press, published in 1998, reprinted in 2008, edited by Zhuang Ruilin), the content of unsaturated fatty acids in Camellia oleifera...

Problems solved by technology

[0005] But camellia oleifera is a natural cross-pollinated plant, and the improved varieties of camellia oleifera are prone to deterioration when they are propagated by seeds, which cannot maintain the excellent properties of the improved varieties of camellia oleifera, and must be propagated asexually to maintain the species.

Moreover, camellia oleifera is a perennial woody plant, which is slow to put into production and difficult to change species. Once put into production, it can last for decades or hundreds of years. Therefore, when the country vigorously advocates and subsidizes the development of camellia oleifera, all places are scrambling to buy seedlings of Camellia oleifera. , and these improved seedlings are in short supply. At present, the price of improved seedlings of Camellia oleifera in many camellia farms has soared to 2 yuan per plant, and there is even a situation of unscrupulous seedlings being supplied.
