Embodiment 1

[0027] Follow the steps below to propagate Xuexiahong cuttings:

[0028] (1) Substrate preparation: Use peat soil and river sand as the substrate (volume ratio 1:1). Mix the substrate evenly. The thickness of the substrate is about 9cm. Spray the substrate with 0.5wt% potassium permanganate solution for pouring. Penetrate the substrate as the standard, seal it with a plastic film for 3 days and then uncover it for use;

[0029] (2) Harvesting ears: In the early morning, use Xuexiahong 3-year-old plants as the female parent, and use robust, disease-free semi-lignified young shoots with a thickness of 0.5 to 0.8 cm, which can be used as needed;

[0030] (3) Cutting preparation: Cut the cuttings into short ears of 7~10cm, keep 2~3 internodes, cut the upper part of the cuttings flatly, cut the lower part 30~45°, about 1cm away from the nodes, and keep 2 at the top of the cuttings. ~3 leaves, put the trimmed cuttings into clean water to moisturize;

[0031] (4) Rooting agent treatment: ta...

Embodiment 2

[0038] The cutting propagation of Xuexiahong was carried out according to the steps of Example 1, and the rooting agent was 300 mg / L naphthalene acetic acid.

[0039] The statistical results are: the rooting rate of cuttings is 86.7%, the average number of adventitious roots is 4.9, the longest adventitious root length is 4.5cm, and the average root length is 2.6cm.

Embodiment 3

[0041] The cutting propagation of Xuexiahong was carried out according to the steps of Example 1, and the rooting agent was 500 mg / L naphthalene acetic acid.

[0042] The statistical results are: the rooting rate of cuttings is 36.7%, the average number of adventitious roots is 4.8, the longest adventitious root length is 3.8cm, and the average root length is 1.8cm.

Abstract

The invention belongs to the technical fled of asexual reproduction of plants and particularly relates to a cutting propagation method for Ardisia villosa Roxb. The method comprises steps of substrate preparation, shoot collection, cutting preparation, processing with a rooting agent, cutting, post-cutting management, transplanting and the like. The cutting method has the advantages that excellent properties of female parents of the Ardisia villosa Roxb can be maintained, the survival rate of plants is high, the rooting rate can be higher than 85%, the transplanting survival rate can be higher than 95%, the propagation speed is high, orderly and sturdy growth is realized, further, the cutting technology is simple in procedure and easy to popularize and apply, the production efficiency is greatly improved, and requirements of landscaping and medicine market can be met better.

Description

technical field [0001] The invention belongs to the technical field of asexual propagation of plants, and in particular relates to a cutting propagation method of red amethyst. Background technique [0002] Xuexiahong ( Ardisiavillosa Roxb), also known as pharmacist, curly-haired Zijinniu, is a small evergreen shrub of the family Zijinniaceae, with a height of 0.5~1m, rare up to 2~3m, and creeping rhizomes. When young, almost the whole plant is covered with taupe or rust-colored villous or hirsute hairs, often curly, and then gradually glabrous. Leaves are papery, elliptic-lanceolate to ovate; single or compound umbels or umbels, covered with rust-colored villous hairs, lateral or attached to the top of lateral special flowering branches; flowering branches 2~15cm long , the elders often have 1~2 leaves or degenerate leaves near the top; pedicel length 5~10mm; flower length 5~8mm; petals lavender or pink, thin white, ovate to broadly lanceolate; fruit spherical, diameter ...
