Embodiment 1
[0021] 1) Choose a site with convenient transportation, sufficient water source, good drainage, and low groundwater level, set up a sunshade net with a shading rate of 65-75%, use a ground seedbed, level the ground, and make a seedbed. The width of the seedbed is 100cm, and the length is 30m. , the surface of the seedbed is covered with ground cloth; the volume ratio of 4:4:1:1 peat: coco peat: yellow core soil: organic fertilizer is mixed evenly as the substrate and then filled into the seedbed to keep the tightness and humidity of the substrate consistent and the thickness of the substrate 8cm, 24 hours before cutting with 0.5% potassium permanganate solution to disinfect the substrate; the dry bulk density of the substrate is 0.28, the total porosity is 62.53%, the large porosity is 16.52%, the small porosity is 46.01%, and the maximum water holding capacity Rate 2.22, pH value 5.56, EC value 3.56, total nitrogen 2.41%, total phosphorus 4046.23mg / kg, total potassium 7021.22m...

Abstract
The invention relates to a blue chip horizontal pavement juniperus chinensis cuttage propagation method, which belongs to the technical field of plant propagation and is characterized by comprising the following steps that: 1) 3 to 5 parts of peat, 3 to 5 parts of coconut tree branny, 0.5 to 1.5 parts of yellow core soil and 0.5 to 1.5 parts of organic fertilizers according to the volume ratio are used as substrates to be uniformly mixed and are filled into a seedling bed; 2) the proper cuttage time is early March, and autumn plants in the last year are subject to the ear shearing; 3) the base parts of ears of cuttage branches are soaked for 2 to 3 seconds by 180 to 220 ppm of Sensheng No.2 plant root prompters; 4) seeding bed cuttage is adopted, and the process enters a management maintenance stage; and 5) the seedling tempering is carried out when the rooting rate reaches about 90 percent. The blue chip horizontal pavement juniperus chinensis cuttage propagation method has the advantages that the rooting condition is good, the finished product rate reaches higher than 96 percent, in addition, the propagation operation of the method is simple, the propagation speed is high, the plants can adapt to the climate and soil environment in China, and good market prospects are realized.
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 blue chips. Background technique [0002] Blue chip tiled juniper Juniperus horizontalis 'Blue Chip', Cupressaceae, Juniperus, evergreen coniferous tree, low floor shrub, felt sheet-like, 20.0 cm -45.0 cm high, crown width 1.8m-2.4m,. The bark is brown and smooth; there are needles and scale leaves, alternately opposite, in spring, summer and autumn, it is green, olive, gray green, dark green or yellow green, and partly turns purple or brown in winter, and the cones are berry-like , light blue, the fruiting period is October-November. [0003] Blue chip tile juniper likes light, likes soil rich in organic matter or sandy soil, drought-tolerant, medium growth, likes well-drained, slightly acidic, neutral and slightly alkaline soil, salt-alkali resistant, mainly used for ground cover It can be planted as a rock plan...
