Embodiment 1
[0025] 1) Select slightly acidic, neutral and slightly alkaline soils to establish ear picking nurseries and cutting seedbeds in the female parent area. The row spacing of the ear picking gardens is 40cm×40cm, the density is 2500 plants / mu, and a sunshade with a shading rate of 65% is erected net. The ground seedbed is used for cutting propagation, the ground is flat, the height difference between the center and the edge of the seedbed is less than 2cm, the seedbed is 100cm wide and 40m long, and the surface of the seedbed is covered with ground cloth.
[0026] 2) Use peat: vermiculite: perlite: yellow core soil = 4:2:1:3 (volume ratio) as the matrix, mix evenly, fill it into the seedbed, keep the tightness of the matrix, and the thickness of the matrix is 8cm, use 900 Doubling the potassium permanganate solution for disinfection, and complete the work 24 hours before the cutting; the dry bulk density of the substrate is 0.46, the total porosity is 55.67%, the large porosity...

Abstract
The invention relates to a cuttage propagation method for platycladus orientalis 'Raffles', and belongs to the technical field of plant propagation. The cuttage propagation method comprises the following steps of: 1) selecting appropriate propagation lands; 2) preparing a matriz; 3) cutting spikes to obtain cuttage branches; 4) performing cuttage; 5) erecting an arch shed; 6) watering after 8 to 12 day and 7) performing seedling refining after 105 to 115 day. By the cuttage propagation method for the platycladus orientalis 'Raffles', a rooting condition is good, and yield is over 80 percent; when the method is used, the platycladus orientalis 'Raffles' easily propagates and propagation speed is high; and the platycladus orientalis 'Raffles' can adapt to the climate soil environment of China and has a good market prospect.
Description
technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cutting propagation method for cedar. Background technique [0002] cedar Platycladus orientalis 'Raffles', Cupressaceae, Arborvitae, evergreen coniferous trees, shrubs or small trees, crown cone-shaped or tower-shaped, branches spread out, crown cone-shaped, large branches obliquely spread, branchlets erect and flat; scale leaves are small, fan-shaped, Tight, slightly curly, blue-green, dark green on the surface, yellow-green on the back, with transparent round glandular spots, which turn bronze or reddish-brown in winter; the cones are oval, fleshy, ovate, and the female fruit is ripe Silvery white luster. [0003] Cedar likes light, likes humid climate, likes good drainage, can grow in slightly acidic, neutral and slightly alkaline environments, resists wind and frost, has strong resistance to various soil adversities, and has very good cold resistan...
