Embodiment 1

[0025] (1) Select a 50-hole tray as a container, fill it with a medium that mixes pine scales, Fafade peat, and perlite at a volume ratio of 4:1:5, and adjusts the pH to 6.5-6.8. Use 0.5% potassium permanganate to pour through the medium for disinfection, and place it neatly for later use after completion.

[0026] (2) In April when clematis grows vigorously, select the branches that were born in the current year, semi-lignified, strong, and free from diseases and insect pests as cuttings. It is cut into double-bud cuttings, that is, two nodes are left on each cutting, the upper node is 0.5 cm away from the upper incision, the lower node is 3 cm away from the lower incision, and 1-2 leaves are reserved at the upper node. Spray 0.1% potassium dihydrogen phosphate solution and 75% thiophanate-methyl 800 times solution on it in the first 3-5 days of pruning.

[0027] (3) Using the principle of "insert harvesting and plugging", immerse the 2cm of the treated cuttings into the 100...

Embodiment 2-4

[0034] In Examples 2-4, except that the formulation of the matrix was changed, the rest of the steps were the same as in Example 1. See Table 1 and Table 2 for the specific matrix formulation and seedling raising results.

Embodiment 5

[0035] Embodiment 5, control group

[0036] Taking river sand as the control group, the experiment was carried out using the conventional method of cutting seedlings of clematis. (Please briefly describe the method)

[0037] (1) Use the 60cm*40cm seed ball frame as the container, and use river sand with a particle size of 0.5-0.8mm as the medium. In order to prevent the river sand from leaking out, use non-woven fabric on the bottom of the seed ball frame and Lay around.

[0038] (2) In April when the clematis grows vigorously, select the healthy, light brown, and pest-free branches of the current year as cuttings. It is cut into single-bud cuttings, that is, there is a node on each cutting, the node is 0.5 cm away from the upper incision, and 3 cm away from the lower incision, and 1-2 leaves are reserved at the node. Spray 0.1% potassium dihydrogen phosphate solution and 75% thiophanate-methyl 800 times solution on it in the first 3-5 days of pruning.

Abstract

The invention provides a method for raising seedlings of clematis by cutting. Each selected cutting slip has is provided with two nodes; a distance from the upper node to an upper notch is 0.5 cm; the distance from the lower node to a lower notch is 2-3 cm; and 1-2 leaves are reserved at the upper node. A cutting medium comprises loose bract, peat and perlite; a cutting depth is 2-3 cm. A cutting hole tray is placed on a prepared iron stand, and an arch shed is set up on the iron stand. After most of cuttings root, the water containing amount of the medium is kept at 60-70%, and films are uncovered gradually for ventilating. When the roots in the hole tray can wind most of the medium, the cuttings are transplanted to a feeding block for seedling management. By the method disclosed by the invention, the rooting percentage of the cutting slips is high; the rooting amount is large; the roots are full and thick, and are distributed evenly; the survival rate of clematis cutting seedlings is greatly increased; the whole seedling raising time is shortened; a large amount of clematis seedlings can be bred in a short time; the breeding efficiency of clematis is greatly improved; and good basis is provided for implementing industrialization of clematis.

Description

technical field [0001] The invention belongs to the field of plant technology cultivation, and in particular relates to a cutting seedling raising method of clematis. Background technique [0002] Clematis ( Clematis florida Thunb.) is Ranunculaceae, clematis, perennial deciduous or evergreen woody vines, which are entangled by petioles, and a few are erect herbs with perennial roots. Its flower types and colors are rich and varied, and the flowers are beautiful and luxuriant. The flowering period is from early spring to late autumn (there are also a few varieties that bloom in winter), and it has high ornamental value. It can be planted beside walls and windows, or attached to trees and shrubs, planted between rockeries and rocks, and climbed on columns, arches, fences, and fences. Its elegant posture can be called the best of vines. Therefore, it enjoys the reputation of "Queen Fujimoto". [0003] However, there are not many clematis in the domestic market at present...
