Embodiment 1

[0022] 1) Choose a site with slightly acidic, neutral and slightly alkaline soil, good drainage, low groundwater level, convenient transportation, and sufficient water sources, and set up a single greenhouse or a conjoined greenhouse, plus a sunshade net with a shading rate of 65%. In the hybrid fast-growing cypress female parent area, the seedbed is leveled, the seedbed is 110cm wide, and the length is 30m. The planting row spacing in the ear-picking garden is 40cm×40cm, and the density is 2500 plants / mu;

[0023] 2) Mix peat: vermiculite: perlite: yellow core soil with a volume ratio of 6:2:1:1 as the substrate and mix evenly. Install the substrate with a 72-hole tray to keep the tightness of the substrate consistent. The size of the tray is 54cm in length, The width is 27cm, the depth is 5.5cm, and the substrate is disinfected with 0.5% potassium permanganate solution 24 hours before cutting; the dry bulk density of the substrate is 0.30, the total porosity is 54.89%, the la...

Abstract

A method for cuttage propagation of cupressus leighton 'Green' belongs to the technical field of plant propagation and is characterized by including steps: firstly, establishing a cutting orchard for female parents of cupressus leighton 'Green' on a proper propagation land; secondly, making peat, vermiculite, pearlite and loess into matrix according to a volume ratio of 5-7:1-3:0.5-1.5:0.5-1.5; thirdly, cutting an autumn shoot of last year to obtain a cutting from a female parent of cupressus leighton 'Green' at the cuttage time, early March; fourthly, dipping a base of the cutting in plant rooting agent Sensheng No.1 at the speed 180-220ppm for two to three seconds; fifthly, performing cuttage on a seedling bed prior to management and maintenance; and sixthly, removing mulch for full-light culture on the fifty-fifth to the sixtieth day after cuttage when rooting rate reaches about 90%. By the method, rooting of cuttings is good, and yield reaches above 90%. The method is simple and fast in propagating.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cutting propagation method for hybrid fast-growing cypress. Background technique [0002] Hybrid fast growing cypress Cupressus leighton 'Green' belongs to the genus Cypress of Cupressaceae, evergreen coniferous tree, tree, tree height 20-25m, crown width 6-9m, dense branches and leaves, tree shape upright, conical; bark grayish brown, bark lobes fall off and the trunk is smooth , the branchlets are covered with scale leaves, the leaf tips are conical, the scale leaves are dark green, yellow-green in winter, mashed and fragrant; the cones are round. [0003] Hybrid fast-growing cypress does not have strict requirements on soil types. It can grow in acidic, neutral and slightly alkaline soils. It is resistant to barrenness and grows rapidly in deep, loose and fertile land. Poor growth, frost-resistant; light-loving, good growth under full light conditio...
