Embodiment 1
[0022] 1) Choose well-drained, slightly acidic, neutral and slightly alkaline soils, and establish ear-picking nurseries in the female parent area. The planting density is 40cm×40cm, and the density is 2500 plants / mu; at the same time, establish a cutting propagation area, using ground seedbeds , the height difference between the center and edge of the bed surface is less than 2cm, the seedbed width is 100cm, the length is 40m, and the surface is covered with ground cloth; mix peat with a volume ratio of 3:4:2:1: reed moss: perlite: organic fertilizer as the matrix Evenly, fill it into the seedbed, keep the tightness of the matrix consistent, the thickness of the matrix is 8cm, and sterilize the matrix with a 700-fold potassium permanganate solution 24 hours before cutting; the dry bulk density of the matrix is 0.18, and the total porosity is 66.13%. , large porosity 20.65%, small porosity 45.48%, maximum water holding rate 3.02, pH value 5.96, EC value 3.06, total nitrogen...

Abstract
The invention discloses a cuttage propagation method for Juniperus horizontalis 'Bar Harbor' and belongs to the technical field of plant propagation. The method is characterized by comprising the following steps of: 1) filling peat, pulverized reed leaves, pearlite and an organic fertilizer in a volume ratio of (2-4):(3-5):(1-3):(0.5-1.5) which are taken as matrixes into a seedbed; 2) picking autumn tips obtained last year from female parents of the Juniperus horizontalis 'Bar Harbor' and cutting spikes, wherein the appropriate cuttage time is early March; 3) impregnating ear bases of cottage branches for 2 to 3 seconds by using a Sensheng No.5 plant root promoter at the concentration of between 180 and 220ppm; 4) performing cuttage by using the seedbed, and entering a management and maintenance stage; and 5) performing seedling hardening when the rooting rate reaches about 90 percent. By the cuttage propagation method for the Juniperus horizontalis 'Bar Harbor', the rooting condition is good, and the yield can reach over 93 percent; and the method is high in propagation speed, can adapt to climate and soil environments in China, and has good market prospect, and the propagation operation steps are simple.
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 Bagang. Background technique [0002] Bar Harbor Tiled Juniper Juniperus horizontalis 'Bar Harbor', Cupressaceae, Juniperus, evergreen coniferous tree, low shrubs on the ground, creeping into felt sheets, tree height 15.0cm-30.0cm, crown width 1.2m-3.0m; bark brown, smooth, branches and leaves Dense, with large branches, with needles and scales, green, olive, gray-green, dark green or yellow-green in spring, summer and autumn, turning purple in winter; cones are small, berry-shaped, blue, The fruiting period is October-November. [0003] 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, and is resistant to salt and alkali. It is mainly used for ground cover planting , as rock plants; can be ...
