Embodiment 1

[0034] The present embodiment provides a kind of method for cutting propagation of long-stem Hedinglan, which comprises the following steps:

[0035] S11. Preparation of cutting materials:

[0036] Select the 1-year-old healthy branches of the long-stem Hedinglan, remove the stem nodes that have grown inflorescences from the selected branches, and cut them into cuttings according to every 2 stem nodes for subsequent use;

[0037] S12. Laying of cutting substrate and seedbed:

[0038] Select orchid gravel with a particle size not greater than 10mm, and lay it into a seedbed with a thickness of 10cm;

[0039] S13. Cutting and induction:

[0040]After the seedbed laid in step S12 is fully wetted by spraying water, the cuttings in S11 are inserted into the matrix at an angle of 20 degrees between the cuttings and the bed surface of the seedbed, and the degree of exposure of each cutting matrix is ​​4 cm. Spray once every three days and add gibberellin (GA) 1mg / L, the foliar fer...

Abstract

The invention discloses a method for the cutting propagation of Phaiuslongicruris Z.H.Tsi and a cutting propagation medium of the Phaiuslongicruris Z.H.Tsi. The method comprises a step of cutting a branch of the Phaiuslongicruris Z.H.Tsi, removing stem segments of inflorescences on the branch, and making a cutting by cutting, a step of inserting the cutting into a cutting medium of the Phaiuslongicruris Z.H.Tsi after wetting, and a step of carrying out cutting management processing including the spraying of a leaf fertilizer on the cutting on the cutting inserted into the cutting medium. According to the method, the branch of the Phaiuslongicruris Z.H.Tsi is used as a propagation tissue, the propagation is carried out by using a cutting mode, and the disadvantages of seed employment, low division propagation efficiency and high propagation condition at present are effectively avoided. In addition, the selected Phaiuslongicruris Z.H.Tsi cutting is inserted into the cutting medium of thePhaiuslongicruris Z.H.Tsi for propagation, therefore, the propagation survival rate is effectively improved, and the stability of the variety can be ensured.

Description

technical field [0001] The invention belongs to the technical field of plant tissue propagation, and in particular relates to a method for cutting and propagating a long-stem Hedinglant and a substrate for cutting and propagating a long-stem Hedinglant. Background technique [0002] Phaius longicruris Z.H.Tsi is a cylindrical pseudobulb, 20-40 cm long, 1.3-2 cm thick, with 3-8 nodes and 5-7 cm long internodes. The leaves are usually 6, alternate on the upper part of the pseudobulb, the leaves are elliptic or elliptic-lanceolate, the scapes are usually 2, extracted from the base or near the base, up to 45 cm long; the inflorescence peduncle is 5 mm thick, sparse 3-5 sheaths, glabrous; racemes with a few flowers, medium-sized flowers, open, sepals and petals light yellow-green; petals glabrous, obovate-lanceolate, pollen clusters nearly ovate-triangular; flowering period 8 -October. The long-stem Hedinglan is produced in southern Yunnan (Jinghong and Mengla) in China. It is ...
