Embodiment 1

[0034] Embodiment 1: cutting propagation method of the present invention

[0035] 1. Seedbed matrix disinfection

[0036] Use perlite as the cutting substrate, and sterilize the substrate before cutting. Use 0.3% potassium permanganate solution to spray and disinfect the substrate, and ensure that the substrate is covered with plastic film for 4 to 5 days before use.

[0037] 2. Collection of cuttings

[0038] From April to August every year, collect 1 to 2-year-old lignified, robust and pest-free branches of Pyracantha clown as cuttings. The thickness of the branches is generally 2-3mm. Ear picking should be carried out when the dew is not dry in the morning on a cloudy or sunny day, and the ear strips should be placed in a bucket with clear water. Before ear picking, tools such as branch shears must be disinfected, and disinfection can be sprayed with 75% alcohol.

[0039] 3. Making cuttings

[0040] The collected branches should be eared immediately. When cutting, remo...

Embodiment 2

[0056] Embodiment 2: Comparison test of cutting propagation of clown firethorn

[0057] Contrast experiment is compared with the cuttage propagation technology taught by the Pyracantha clown cutting propagation technology of the present invention and the literature "Pyracantha clown cutting propagation" (Zheng Yongping, Fan Wenfeng, Wei Bin, Xu Shaoyuan, Chinese Flower Horticulture 2010 No. 6) Test, the test results prove that the Pyracantha clown breeding method of the present invention is better than the existing Pyracantha clown breeding method.

[0058] Test 1: The Pyracantha clown cutting propagation technology described in the present invention was tested in three batches on May 8, June 8, and August 6. Please refer to Example 1 for detailed operations.

[0059] Experiment 2: The cutting propagation technique taught in the document "Clown Firethorn Cutting Propagation" (Zheng Yongping, Fan Wenfeng, Wei Bin, Xu Shaoyuan, Chinese Flower Horticulture, Issue 6, 2010), the de...

Abstract

The invention relates to the technical field of plant rapid propagation and discloses a pyracantha fortuneana harlequin cuttage breeding method. The cuttage breeding method of the invention comprises following steps: firstly collecting and preparing pyracantha fortuneana harlequin cutting slips; then, the stem bases of the cutting slips are soaked in a solution containing ABT1, IBA and Vc; secondly, the cutting slips are inserted in a disinfected seedbed and cuttage late stage management is performed; finally, transplanting, potting and maintenance are carried out. According to the method of the invention, ABT1, IBA and Vc are used as a pretreatment phytohormone solution for pyracantha fortuneana harlequin; processing mode is adjusted as soaking; other main factors affect the cuttage breeding effects, such as seedbed substrate, spike collecting time, the types and concentration of disinfectant, hormone concentration and soaking time and cuttage late stage management, are optimized to obtain a set of mature pyracantha fortuneana harlequin cuttage breeding method; quick and large scale breeding is fulfilled; the problems of cutting slip browning, low rooting rate and transplanting survival rate in the present cuttage methods are solved.

Description

technical field [0001] The invention relates to the technical field of rapid plant propagation, in particular to a method for cutting and propagating Pyracantha clown. Background technique [0002] Pyracantha fortuneana'Harlequin', an evergreen shrub of the genus Pyracantha in the family Rosaceae, is a cultivar of Pyracantha cultivated in Japan, with single leaves, leaves ovate, obovate-oblong or obovate, and apex blunt Round and slightly concave, with blunt serrations on the edges. The leaves have patterns, like a clown's face, hence the name Pyracantha clown, and the leaves are pink in winter. The flowers are white, the flowering period is from March to May, and the fruiting period is from August to November. The small red pome fruit has a fruit-bearing time of up to 3 months. It is a good flower, fruit and foliage plant. [0003] Pyracantha clown is a new variety of excellent mosaic ground cover plant. It can be planted in large areas in park green spaces. It can not o...
