Embodiment 1

[0021] 1) Choose a well-drained, slightly acidic, neutral and slightly alkaline soil, and a site with sufficient water sources, set up a conjoined greenhouse, add a sunshade net with a shading rate of 65%, and build an elevated seedbed in the shed. The height difference between the center and the edge of the bed surface is less than 2cm, the width of the seedbed is 100cm, and the length is 30m. The bed is covered with ground cloth, and the volume ratio of peat: vermiculite: perlite: organic fertilizer is 6:2:1:1. Pave and fill the matrix on the bed and carry out disinfection treatment with 500 times of potassium permanganate solution 24 hours before the cutting, the matrix thickness is 8cm; the dry bulk density of the matrix is ​​0.23, the total porosity is 62.13%, and the macroporosity is 17.76%. Small porosity 44.37%, maximum water holding rate 2.47, pH value 5.76, EC value 2.30, total nitrogen 3.37%, total phosphorus 5268.18mg / kg, total potassium 10428.19mg / kg, calcium 2183....

Abstract

The invention discloses a cuttage propagation method of Juniperus conferta 'blue pacific', belonging to the technical field of plant propagation. The method comprises the following steps of: 1, laying a matrix on a seedling bed, wherein volume ratio of peat to vermiculite to pearlite to manure in the matrix is (5-7):(1-3):(0.5-1.5):(0.5-1.5); 2, carrying out cuttage in a proper time period of the first ten days of November, cutting tassels from lateral branches of a female parent of Juniperus conferta 'blue pacific'; 3, soaking the bottom parts of the tassels with a plant rooting agent Sensheng No.3 (180-220ppm) for 2-3 seconds; 4, carrying out seedling bed cuttage and then carrying out management and protection; and 5, hardening seedlings when rooting rate is higher than 80%. The cottage propagation method of Juniperus conferta 'blue pacific' has the advantages of simplicity in propagation operation and high propagation speed, is adapted to the climate and soil environment of China and has bright 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 of blue Pacific coast juniper. Background technique [0002] blue pacific coast juniper Juniperus conferta 'Blue Pacific', Cupressaceae, Juniper genus, evergreen coniferous tree, low shrub on the ground, light brown bark, low plant type, arched branches, wide creeping stretch, tree height 0.5m-0.8m, crown width Up to 3m or more; needle-like leaves, 2cm-3.5cm long, whorled, blue-green. [0003] Blue Pacific coast juniper likes light, likes well-drained, slightly acidic, neutral and slightly alkaline soils, is resistant to salt and alkali, and grows quickly. It is mainly used for ground cover planting, and can also be used as rock plants, bonsai, and can be planted in coastal areas. , to prevent soil erosion. [0004] Blue Pacific coast juniper is native to the northern coast of Japan. It has high ornamental value and wide adapt...
