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 from a 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 reaches more 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

Thunder is run quickly and is reached Kaohsiung Selaginella tamariscina cuttage breeding method
Technical field
The invention belongs to the plant propagation technical field, be particularly related to thunder to reaching Kaohsiung Selaginella tamariscina cuttage breeding method.
Background technology
Thunder is run quickly and is reached the Kaohsiung Selaginella tamariscina Juniperus communis' Repanda ' is subordinate to the Cupressaceae juniper and belongs to, evergreen coniferous tree, and the floor file brushwood, tree crown is short, oblate spheroid, the bark taupe, high 0.5m-0.8m, the hat width of cloth can reach 1.0m-2.5m; Withe approaches and dense arrangement, needle is arranged and drape over one's shoulders needle, and is blackish green in the season of growth, is with silver color, bronze colour to winter, drapes over one's shoulders the needle tip and curls, soft.
' Lei Benda ' Kaohsiung Selaginella tamariscina happiness light, cold resistance is strong, and is drought-enduring, requires not strict to soil types; The happiness draining is good, subacidity, neutrality and alkalescence soil, and growing way is medium, is planted with being mainly used in, also can do rock plant; Potted landscape can be planted in the grit district, prevents erosion.
Thunder is run quickly and is reached Kaohsiung Selaginella tamariscina reward value height, and wide accommodation all can be planted in China northeast, North China, southwest and subtropical zone; Being used as ground cover plant more abroad, but not obtaining exploitation at home as yet, is good green tree species, has vast market prospect.Through the inquiry to data of literatures, not seeing at present domesticly has thunder to run quickly to reach relevant scientific paper and the patent of Kaohsiung Selaginella tamariscina cottage propagation technology, and this field still belongs to blank.
Summary of the invention
To the problems referred to above that exist in the prior art, the objective of the invention is to design provides a kind of thunder to the technical scheme that reaches Kaohsiung Selaginella tamariscina cuttage breeding method, and it is simple to operate, reproduction speed is fast, and cuttage survival rate is filled up the blank of domestic correlation technique up to 80%.
Described thunder is run quickly and is reached Kaohsiung Selaginella tamariscina cuttage breeding method, it is characterized in that may further comprise the steps:
1) with volume ratio be the import peat of 4-6:2-4:0.5-1.5:0.5-1.5: coconut palm chaff: vermiculite: perlite is puddled evenly as matrix; Be filled in the dish of 72 holes; Keep the matrix elasticity consistent, fill the cave dish of matrix, put successively on the seedbed; Put 5-7 only for every square metre, with 700-900 times of liquor potassic permanganate matrix is carried out disinfection preceding 24 hours of cuttage;
2) suitable cutting time is an early March; Cuttage in 1 year 1 time takes the autumn of last year to cut fringe slightly from thunder to reaching Kaohsiung Selaginella tamariscina female parent, and being cut into length is the cuttage branch of 6.5-7.5cm; Keep the top; Lower cut is level and smooth, wipes out the needle of fringe bar bottom 2.5-3.5cm, and leaf site 3.5-4.5cm is stayed on top;
