Embodiment 1

[0023] The specific process of multicolored stellite cutting propagation is as follows:

[0024] 1. Management of ear-picking female parent: In mid-February, strong pruning was carried out on the ear-picking nursery of the five-colored stellite, and the height of the female parent was kept at 15-20 cm, and the stubble was carried out. At the beginning of March, apply decomposed manure at a distance of 30-40cm from the root of the female parent as the base fertilizer to promote the germination of more and thicker spikes of the year. The amount of base fertilizer is 100-250kg / hm 2 ;

[0025] 2. Cutting time: from mid-November to the end of March of the following year;

[0026] 3. Preparation of the slotting bed: spread 20cm thick clean river sand on the pre-built electric hotbed, the electric hotbed is 60-80cm wide, and the electric hotbed is set in a simple steel shed;

[0027] 4. Preparation of rooting agent: Dissolve 100-300 mg of ABT1 rooting powder and 100-200 mg of napht...

Embodiment 2

[0034] A. Rooting agent screening experiment

[0035] Experimental method--preparation of rooting agent: No. ABT1 rooting powder (or IAA) and naphthaleneacetic acid (NAA) are first dissolved in 200ml volume concentration 95% ethanol, add water to 1kg and mix evenly, set aside.

[0036] The rooting agent is provided with 17 kinds of treatments, and the specific treatments are shown in Table 1. The hormone unit in each treatment is mg / kg, and other steps are the same as in Example 1. Under different rooting agents and concentrations, the rooting rate of cuttings is also different, see Table 1:

Embodiment 3

[0048] Experimental method-preparation of rooting agent: Dissolve 100-300 mg of ABT1 rooting powder and 100-200 mg of naphthaleneacetic acid (NAA) in 200 ml of 95% ethanol, add water to 1 kg and mix well. Dilute the base of the cuttings with 50% thiophanate-methyl wettable powder 800-1500 times at a medium speed and then dip it in the prepared rooting agent for 1s-5s at a medium speed, and insert it into the laid cutting substrate . The cutting substrate was set to 9 treatments, see Table 3 for details. Other steps are with embodiment 1. Under different cutting substrate treatments, the rooting rate of cuttings is different, see Table 3:

[0051]

[0052] Result analysis--From Table 3, it can be seen that different cutting substrate treatments have different effects on the rooting rate of multicolored stellite cuttings. It can be seen from...

Abstract

The invention discloses a cutting propagation method for trachelospermum jasminoides. The cutting propagation method includes preparing cutting beds, to be more specific, laying river sand on electric heating hot beds and then flatly laying a layer of culture substrates on the river sand; carrying out cutting, to be more specific, disinfecting cutting of the trachelospermum jasminoides in winters, then soaking the cutting in rooting agents for a period of time and then inserting the cutting into the laid cutting substrates; carrying out post-cutting management, to be more specific, keeping the temperatures of the electric heating hot beds at 20-25 DEG C under the control, keeping the humidity of the substrates at 65%-80% under the control in 20 d, keeping the humidity of air at 90-95%, keeping the humidity of the substrates at 50%-60% under the control in 20 d after cutting is carried out, and keeping the humidity of the air at 80%-90% under the control in 20 d after cutting is carried out until the root systems of the bases of the cutting completely grow out; carrying out transplanting in a period of time after the roots grow. The cutting propagation method has the advantages that current-year branches of the trachelospermum jasminoides are used as the cutting, cutting is carried out on the cutting on the electric heating hot beds in the winters, reasonable management is carried out, and accordingly the propagation speeds and the rooting rates can be greatly increased.

Description

technical field [0001] The invention relates to a multicolored stellite propagation method, in particular to a multicolored stellite cutting propagation method. Background technique [0002] Trachelospermum jasminoides'Variegatum' is an evergreen woody vine of the genus Trachelospermun in the Apocynaceae family. The leaves are oval to oval. Composed of variegated leaves, green-bottomed blaze leaves and green leaves, it is mainly maroon in winter. The leaves are rich in color, resembling flowers, very beautiful, and have a long viewing period. It is a good material for climbing, vertical and other three-dimensional greening. At the same time, It has strong resistance, high temperature resistance, cold resistance, and humidity resistance. It is these characteristics that attract the majority of seedling traders. Among the many excellent ground cover plants, multicolored stellite is favored by people for its wide distribution, colorful leaves, long ornamental period and multip...
