Embodiment 1

[0021] 1) Mix the substrate evenly, fill it into the 72-hole tray, and keep the tightness of the substrate consistent. The tray specifications are 54cm in length, 27cm in width, and 5.5cm in depth. Place 6 per square meter, and sterilize the substrate with 0.5% potassium permanganate solution 24 hours before cutting. The substrate formula is peat: vermiculite: perlite: organic fertilizer = 6:2:1: 1 (volume ratio), dry bulk density 0.23, total porosity 62.13%, large porosity 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 5268.18 mg / kg, total potassium 10428.19mg / kg, calcium 2183.52mg / kg, magnesium 340.60mg / kg, copper 0.16mg / kg, zinc 368.33mg / kg, boron 485.65 mg / kg, iron 5569.61 mg / kg, manganese 334.93mg / kg, molybdenum 11.45 mg / kg, aluminum 6793.18mg / kg, lead 9.28mg / kg, sodium 2678.20 mg / kg, nickel 28.24mg / kg, sulfur 2777.98mg / kg;

Abstract

The invention relates to a blue mountain sabina chinensis cuttage propagation method, which belongs to the technical field of plant propagation and is characterized by comprising the following steps that: 1) cuttage substrates consist of 5 to 7 parts of peat, 1 to 3 parts of vermiculite, 0.5 to 2 parts of perlite and 0.5 to 2 parts of organic fertilizers according to the volume ratio through being mixed; 2) the cuttage time is early March, and autumn plants of each side branch in the last year are collected from female parents of the blue mountain sabina chinensis for ear shearing; 3) the base parts of ears of cuttage branches are soaked for 2 to 3 seconds by 2400 to 2600 ppm of Sensheng No.2 plant root prompters; 4) 72-hole plug discs are adopted for cuttage, and the process enters a management maintenance stage; and 5) after 120 to 130 days of the cuttage and when the rooting rate reaches about 70 percent, the seedling tempering is carried out. The blue mountain sabina chinensis cuttage propagation method has the advantages that the plants can adapt to the climate and soil environment in China, the rooting condition is good, the finished product rate reaches 70 percent, in addition, the operation is simple, the propagation speed is high, 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 cutting propagation method of blue-carpeted alpine juniper. Background technique [0002] Blue Carpet Alpine Juniper Juniperus squamata ‘Blue Carpet’, belonging to the genus Juniperaceae, is an evergreen conifer and ground shrub native to the Himalayas and some other Central Asian mountains. The tree shape is low, the tree height is 20.4-40.5cm, the crown width is 1.2-2.5m; the bark is reddish brown and flakes off; the branches and leaves are dense, the leaves are needle-lanceolate, 1-2.5cm long, and the leaf color is in spring, summer, It is blue-green and gray-green in autumn, and some leaves turn bronze in winter; the cones are black. [0003] Blue Carpet Alpine Juniper has no strict requirements on the soil, and can grow in slightly acidic, neutral or slightly alkaline soils, prefers sandy soil and soil rich in organic matter; strong cold resistance...
