Embodiment 1

[0020] Example 1: In October 2011, branches of male plants and female plants with excellent properties were collected in Weixi County, Yunnan Province. Cutting, hardening and cultivation were all completed in the garden practice base of Southwest Forestry University.

[0021] Selection of cuttings: Select young and middle-aged plants on the annual Torreya yunnanensis branches as cuttings, about 8m long, strong branches, emerald green leaves, no pests and diseases.

[0022] Preservation of cuttings: Preservation of cuttings is the key to the survival of cuttings. After collection, soak them in clean water for 10 minutes and store them in a cool, dark and windless environment. Complete the cuttings within 48 hours.

[0023] Mechanical treatment of cuttings: the petiole of Torreya yunnanensis is short, and 2 / 3 of the leaves at the tip are reserved in the cuttings, and the lower 1 / 3 of the leaves near the stem end are removed by hand or scissors. When removing, pay attention to kee...

Abstract

The invention discloses a method for performing cuttage propagation on Torreya yunnanenssi Cheng et L.K.Fu, belongs to the technical field of plant cultivation, and in particular relates to a method for performing cuttage propagation on Torreya yunnanenssi Cheng et L.K.Fu. The method is characterized by comprising the following steps of: (1) preparing a cutting wood: taking an annual-grown strong branch of which the length is between 8 and 12cm as the cutting wood; (2) putting the cutting wood into mixed liquid of naphthalene acetic acid aqueous solution of 1,000mg/L and chlorothalonil of 2,000mg/L for soaking; (3) paving a brick seedbed with the height of 20cm in a greenhouse tunnel, and paving a sand bed or a matrix bed on the brick seedbed; (4) inserting the cutting wood into the sand bed or the matrix bed; (5) carrying out daily management; and (6) exercising seedling and changing a garden: cultivating a cutting wood seedling root in the open air by changing the small greenhouse tunnel after the cutting wood seedling root grows out of the soil. With the adoption of the method, the problem that the Torreya yunnanenssi Cheng et L.K.Fu difficultly takes root is solved, and the method is simple and feasible and low in cost, so that the blank for performing cuttage propagation on Torreya yunnanenssi Cheng et L.K.Fu for culturing seedlings in a scale mode can be made up.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a cutting propagation method of Torreya yunnanensis. Background technique [0002] Torreya yunnanensis ( Torreya yunnanenssi Cheng et L.K.Fu), an evergreen tree of the Taxaceae family, distributed in the northwestern part of Yunnan, scattered in valleys or hillside coniferous forests and mixed forests of coniferous and broad-leaved trees at an altitude of 2000 to 3400 meters, is a unique tree species in my country, belonging to the genus Torreya The species with the westernmost distribution has important academic significance for the study of the classification and distribution of Torreya. The wood of this tree species is solid, with fine and uniform texture, no cracking, water and humidity resistance, and strong corrosion resistance. It is a high-quality material for manufacturing houses, bridges, furniture, appliances, and farm tools. Its fruit can be used medicinall...
