Embodiment 1

[0023] 1) Select slightly acidic, neutral and slightly alkaline soils, and establish ear picking gardens and cutting seedbeds in the female parent area of ​​Cedar cypress in Jinqiu. , the density is 4000 plants / mu. At the same time, ditching is used as a seedbed, and the bed surface is covered with ground cloth, and the plugs for cuttings are placed;

[0024] 2) Mix peat with a volume ratio of 5:2:1:2: vermiculite: perlite: yellow core soil evenly as a matrix, and install the matrix with a 72-hole tray. The size of the tray is 54cm in length, 27cm in width, and 5.5cm in depth , keep the tightness of the substrate consistent, and disinfect the substrate with 600-800 times potassium permanganate solution 24 hours before cutting; the dry bulk density of the substrate is 0.38, the total porosity is 56.67%, the large porosity is 12.89%, and the small porosity The degree is 43.78%, and the maximum water holding rate is 1.42. pH value 5.47, EC value 0.49, total nitrogen 1.18%, tota...

Abstract

The invention relates to a golden ball thuja occidentalis cuttage propagation method, which belongs to the technical field of plant propagation and is characterized by comprising the following steps that: 1) proper propagation places are selected for building a golden ball thuja occidentalis female parent region ear picking nursery garden; 2) 4 to 6 parts of peat, 1 to 3 parts of vermiculite, 0.5to 1.5 parts of perlite and 1 to 3 parts of yellow core soil according to the volume ratio are adopted as substrates; 3) the proper cuttage time is early March, and autumn plants in the last year arecollected from female parents of the golden ball thuja occidentalis for ear shearing; 4) the base parts of ears of cuttage branches are soaked for 2 to 3 seconds by 1400 to 1600 ppm of Sensheng No.5 plant root prompters; 5) seeding bed cuttage is adopted, and the process enters a management maintenance stage; and 6) after 70 to 78 days of the cuttage and when the rooting rate reaches about 60 percent, the seedling tempering is carried out. The golden ball thuja occidentalis cuttage propagation method has the advantages that the plants can adapt to the climate and soil environment in China, the rooting condition is good, the finished product rate reaches 60 percent, the blank in the relevant technical field is filled, in addition, the operation is simple, and the propagation speed is high.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cutting propagation method of Cedar chinensis. Background technique [0002] Golden Globe Cedar Thuja occidentalis 'Golden Globe', belonging to Cupressaceae Thuja, evergreen coniferous tree, shrub, tree height 0.6-2.2m, crown width 0.9-1.8m, crown conical, oval to round, apex obtuse; bark brown , peeling off in long strips; branchlets are dense, flat, dark green, and the back is often gray-green; the scale leaves are dense and soft, yellow-green or golden yellow, shiny, and have a pleasant fragrance, and the scale leaves are arranged like feathers; female cones There are 8-10 pairs of pearl scales, the surface of the pearl scales is smooth, the female cones turn green to brown, the cones are brown, and the seeds can be propagated naturally. [0003] Golden Ball North American cedar likes light and grows vigorously under full sunlight; likes slightly acid...
