Abstract

The invention provides a film-covered Chinese rose single bud cutting propagation method. The film-covered Chinese rose single bud cutting propagation method comprises the steps of paving a bottom-layer plastic film on a flat seedbed and paving geotechnical cloth on the plastic film, putting a sterile coconut chaff seedling substrate on the geotechnical cloth and thoroughly watering the substrate, selecting Chinese rose branches, dipping the roots of the cuttings with 3-indolebutyric acid rooting powder having the content of 0.10%-0.25%, inserting the cuttings into the substrate and thoroughly watering again, covering the seedbed with the cuttings with a layer of non-woven cloth, covering the non-woven cloth with a top-layer plastic film and wrapping the bottom-layer plastic film and the top-layer plastic film together, controlling the outside environmental temperature of the cutting seedbed within the range of 20-32 DEG C before rooting, after the Chinese rose cuttings root completely and the cutting auxiliary buds begin to germinate and grow, uncovering the top-layer plastic film, uncovering the non-woven cloth 2-4 days later, and performing intermittent spraying watering to ensure that the substrate is wet thoroughly until the seedlings are grown. The film-covered Chinese rose single bud cutting propagation method has the advantages of isolation of the seedling substrate from the outside environment, few cutting diseases, high survival rate, quick seedling growing, simple planting management and low labor investment.

Description

Film covering type Chinese rose single-bud cuttage propagation method

Technical field

The invention belongs to gardening plant vegetative propagation technique field, relate to a kind of film covering type Chinese rose single-bud cuttage propagation method.

Background technology

Cuttage is the vegetative a kind of important method of plant, utilizes the part root of plant, stem or leaf, cuttage root-taking, grows up to complete, independently new plant.Cuttage seeding has the advantage that propagation method is simple, convenient management, seedling are fast, and cuttage seeding can carry out collection cuttage when plant is pruned, and its production cost is lower.In practical application, the cottage propagation of plant mainly contains stem cutting and root inserts two classes, and according to the difference of cuttings character, cuttage is divided into cuttage and epicormic branch cuttage.The general principle of cuttage is: the formation layer of cuttings base portion clip under appropriate conditions, first forms the callus of white, differentiates adventive root subsequently, forms the fibrous root of cuttage seeding, finally sprouts at cuttings top bud, form complete plant.

At present, Chinese rose seedling cottage propagation generally adopts illumination spraying, epicormic branch cuttage raising technology, namely under natural light irradiation condition, with semi-lignified, band blade cuttings, the slotting machine good at drainage ventilation carries out cuttage, takes the technology of automatic intermittent spraying on daytime to promote that cuttings survives in cuttage process.Compared with traditional cuttage, have that cuttage root-taking is easy, planting percent is high, growing-seedling period is short, 1 year can cuttage many batches, fringe bar abundance and the advantages such as scale; There is in application easy grasp, simple to operate, small investment, benefit high.But this method in actual applications, control comparatively strict with Changes in weather ambient humidity, require automatic intermittent spraying by day, cause that water waste is large, personnel control's management difficulty is comparatively large and cuttage rooting uniformity is poor, sapling multiplication survival rate less than optimum efficiency, had influence on Chinese rose seedling and efficiently bred production.

Summary of the invention

Take root inconsistent for overcoming Chinese rose cottage propagation, survival rate is low, management drops into higher problem, the invention provides a kind of film covering type Chinese rose single-bud cuttage propagation method, the method is realized by following technical proposal:

(1) in greenhouse, carry out smooth to seedbed or ground, make it without depression, at seedbed or upper berth, ground one deck bottom plastic foil, the specification requirement of bottom plastic foil thickness is more than 12, and bottom plastic foil repaves the dark geotextiles of one deck, and geotextiles thickness specification is 0.2-0.3 centimetre;

(2) in geotextiles, directly put dry aseptic coconut palm chaff seedling medium, carry out smooth to matrix; Adopt drops shower head to water permeable, make matrix fully moistening, on the plastic film without ponding, watering permeable rear stromal thickness is 5 ~ 8 centimetres;

(3) select healthy Chinese rose branch, the cuttings of shear band blade, blade upper end retains 0.2 ~ 0.6 centimetre of cane, and blade lower end retains the cane of 3 ~ 6 centimetres, and sheared edge is smooth without extruding scar; Cuttings base portion is dipped in the 3-indolebutyric acid root-inducing powder of content 0.10% ~ 0.25%, insert matrix 2 ~ 5 centimetres dark, after seedbed is plugged in flakes, sprinkling irrigation is watered once permeable;

(4) at the seedbed upper cover last layer thickness be plugged be the white non-woven cloth of 15, non-woven fabrics covers the overlying plastic film that thickness is 1-2 silk, the bottom plastic foil of matrix and overlying plastic film are bundled together, allow the moisture of cutting medium and external environment without convection current, in the stage of taking root, under keeping plastic foil, cuttings ambient humidity is more than 95%;

(5) before taking root, cuttage seedbed ambient temperature controls at 20 DEG C ~ 32 DEG C, when temperature is higher than 32 DEG C, adopt shading rate be 50% ~ 70% silver color sunshade net shade, the scattered light produced with sunshade net irradiates cuttage seeding, after shading, temperature of shed, also more than 32 DEG C, can carry out mist cooling in canopy;

(6) after Chinese rose cuttings is taken root completely, individual plant root quantity reaches more than 10, length is more than 0.5 centimetre, or cuttings axillalry bud is when starting germination and growth, first open overlying plastic film, after 2-4 days, open white non-woven cloth again, according to the humidity of matrix, carry out gap spraying to water, guarantee that matrix is fully moistening; After seedling bears three blades, change into and watering every day once, grow up to seedling.

The present invention possesses following advantages and effect:

1, the present invention matrix is carried out, the plastic film wrapped on bottom and upper strata, allow seedling carry out nursery in the environment of relative closure, avoid in the soil of external environment, harmful element and pathogen contamination medium, reduce kind of a Seedling Diseases, improve survival rate, promote seedling early growth;

2, the present invention can realize nutrient to matrix, temperature, humidity accurately controls, and realizes environmental condition stable and consistent, guarantees that seedling grows fast in adapt circumstance, improve kind of a shoot survival percent;

3, the present invention is in sapling multiplication process, and matrix is coated to plastic film wrapped, and the moisture content volatilization in matrix is few, without the need to carrying out the management of round-the-clock water spray to matrix, saves water source, decreases labour and drops into;

4, the plastic foil of more than 12 thickness is adopted can to increase wear-resisting, the breakage-proof ability of bottom at bottom, the geotextiles that bottom covers can prevent from being damaged by bottom plastic foil during cuttage, the white non-woven cloth covered in matrix has the effect of moisturizing, insulation, ventilative, logical light, can also prevent strong sunlight burning to newborn tender shoots.
