Embodiment 1

[0021] 1) Mix the imported peat with a volume ratio of 5:3:1:1: coconut peat: vermiculite: perlite as a matrix, and fill it into a 72-hole plug tray to keep the tightness of the matrix consistent. The size of the plug tray is long 54cm wide, 27cm wide, and 5.5cm deep, the plugs filled with the matrix were placed on the seedbed in turn, 6 per square meter, and the matrix was sterilized with 800 times potassium permanganate solution 24 hours before cutting; The dry bulk density of the matrix is ​​0.16, the total porosity is 90.55%, the large porosity is 31.56%, the small porosity is 58.99%, the maximum water holding rate is 5.14, the pH value is 5.98, the EC value is 0.56, the total nitrogen is 1.32%, and the total phosphorus is 499.09mg / kg , total potassium 6381.55mg / kg, calcium 2607.91mg / kg, magnesium 2454.44mg / kg, copper 5.76mg / kg, zinc 52.73mg / kg, boron 5.13mg / kg, iron 4693.40mg / kg, manganese 115.10mg / kg, Molybdenum 1.88mg / kg, aluminum 2610.01mg / kg, lead 7.96mg / kg, sodium 31...

Abstract

The invention relates to a method for cuttage propagation of Repanda selaginella repanda, which belongs to the technical field of plant propagation, and is characterized by comprising the following steps of: (1) adopting imported peat, coconut residuum, vermiculite and pearlite with the volume ratio being 4-6:2-4:0.5-1.5:0.5-1.5 as matrixes; (2) cutting ears of the autumn growth in last year froma female parent of the Repanda selaginella repanda, wherein the roper cuttage time is the beginning of March; (3)in branch cuttage, adopting 180-220 ppm of dark Sen growth Growth NO.1 plant root-growth accelerant to dip the root parts of ear strips for 2-3 seconds; (4) adopting seedbed cuttage, and entering a management maintenance stage; and (5) exercising seedlings when the rootage rate reachesmore than 80 percent. According to the method for cuttage propagation of the Repanda selaginella repanda, the rootage situation is favorable, the survival rate of cuttage is 80 percent, and the method is easy in propagation operation and fast in propagation speed, can be adaptive to climate soil environment in China, and has better 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 Selaginella Kaohsiung. Background technique [0002] Lei Benda Kaohsiung Selaginella Juniperus communis 'Repanda', belonging to the genus Juniperaceae, is an evergreen coniferous tree, a low shrub on the ground, with a low crown, flat spherical shape, grayish-brown bark, 0.5m-0.8m high, and a crown width of 1.0m-2.5m; thin The branches are thin and densely arranged, with needle-like leaves and lanceolate leaves, dark green in the growing season, silvery or bronze in winter, and the lanceolate leaves are curled at the apex and soft to the touch. [0003] 'Lei Benda' Kaohsiung Selaginella likes light, has strong cold resistance and drought tolerance, does not have strict requirements on soil types, likes well-drained, slightly acidic, neutral and slightly alkaline soils, and grows moderately. It is mainly used for ground cover...
