Abstract

A method for cuttage propagation of chamaecyparis pisifera Filifera Aurea belongs to the technical field of plant propagation and is characterized by comprising steps: firstly, spreading pulverized reed leaves, vermiculite, pearlite, loess and organic fertilizer as matrix on a seedling bed according to a volume ratio of 3-5:1-3:0.5-1.5:1-3:0.5-1.5; secondly, cutting an annual semi-ligneous lateral branch to obtain a shoot from a female parent of chamaecyparis pisifera Filifera Aurea at the proper cuttage time, late June; thirdly, dipping a base of the cuttage shoot in plant rooting agent Sensheng No.2 at the speed of 180-220ppm for two to three seconds; fourthly, performing cuttage on the seedling bed prior to management and maintenance; and fifthly, exercising seedlings on the fiftieth day after cuttage when rooting rate reaches more than 80%. The method is simple in propagation, fast in propagation and applicable to climate and soil of China, and has great market outlook.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cutting propagation method of Japanese cypress japonica dwarf. Background technique [0002] Golden thread dwarf Japanese cypress Chamaecyparis pisifera 'Filifera Aurea Nana', belonging to the genus Cypress of the cypress family, is an evergreen coniferous tree and shrub native to Japan. The tree is short and spherical or tower-shaped, with a height of 0.9-2.8m and a crown width of 0.9-1.8m; the bark is reddish brown, falling off in flakes; the branches are slender and layered, heading and arched and drooping; the scale leaves are yellow-green or golden yellow , the leaves are arranged in spirals, yellow-green, bright in color; the male cones are very small, brown, and the female cones are round, green to brown, in the form of cones. [0003] Golden thread dwarf Japanese cypress likes slightly acidic, neutral and slightly alkaline soil rich in organic ma...
