Cuttage propagation method for juniperus horizontalis 'Wiltonii'

Abstract

The invention relates to a cuttage propagation method for juniperus horizontalis 'Wiltonii', and belongs to the technical field of plant propagation. The cuttage propagation method is characterized by comprising the following steps of: 1) filling reed jasmine, vermiculite, pearlite, yellow subsoil and an organic fertilizer which serve as matrixes in a volume ratio of (2-4):(0.5-1.5):(0.5-1.5):(3-5):(0.5-1.5) into a seedling bed; 2) shearing cuttage spikes from a lateral branch of a juniperus horizontalis 'Wiltonii' parent, wherein cuttage is performed appropriately in the first ten days of November; 3) infusing roots of cuttage branches formed by cutting the spikes in 400 to 600 ppm of No.7 sensheng plant rooting agent for 2 to 3 seconds; 4) performing the cuttage by using a seedling bed, and performing management and maintenance; and 5) when a rooting rate is about 85 percent, performing seedling refining. By the cuttage propagation method for the juniperus horizontalis 'Wiltonii', arooting condition is good, and yield is over 85 percent; when the method is used, the juniperus horizontalis 'Wiltonii' easily propagates and propagation speed is high; and the juniperus horizontalis'Wiltonii' 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 method for laying juniper cuttages for Verdoni. Background technique

[0002] Verdoni tiled juniper Juniperus horizontalis 'Wiltonii', Cupressaceae, Juniperus, evergreen coniferous tree, dwarf shrub, creeping horizontally, tree height 0.15m-0.50m, crown width up to 3m-5m, bark brown; with needles and scales, It is blue-green in the growing season, turns slightly purple in winter, and emits fragrance after being mashed; the cones are berry-shaped, light blue, small in shape, and round in shape.

[0003] Verdoni tiled juniper can grow under full or partial light conditions. It is resistant to drought, salt and alkali, and pollution. It requires good drainage of the planting soil and is not strict on soil properties. It can grow normally in alkaline soil, with a medium growth rate. It can be potted, used as ground cover plants, border plants, used in court...

Examples

Embodiment 1

[0020] 1) Choose a site with medium-to-medium soil fertility and sufficient water source to establish the ear-picking nursery in the female parent area, erect a single greenhouse, and add a sunshade net with a shading rate of 65%. The row spacing of the female parent plant is 40cm×40cm, and the density is 2500 plants / mu. Cutting propagation adopts the ground seedbed method, the ground is flat, the height difference between the center and the edge of the bed surface is less than 2cm, the seedbed is 100cm wide and 40m long, and the surface of the seedbed is covered with ground cloth; the reed with a volume ratio of 3:1:1:4:1 Jasmine: vermiculite: perlite: yellow heart soil: organic fertilizer is mixed evenly as a matrix, and the matrix is ​​filled into the seedbed to keep the tightness of the matrix consistent. The substrate is disinfected; the dry bulk density of the substrate is 0.54, the total porosity is 52.35%, the large porosity is 8.26%, the small porosity is 44.09%, the...
