Embodiment 1

[0016] Embodiment 1: the method for lily rhododendron cutting propagation, is characterized in that comprising the following steps:

[0017] 1. Seedbed laying: The seedbed is set in the glass greenhouse and adopts a brick-concrete structure. Reserve one drainage hole every 80cm at the bottom of the seedbed, and then add stones, pebbles, and coarse sand from bottom to top to increase the drainage and ventilation of the seedbed; lay 8-10cm thick peat + perlite + on the coarse sand Vermiculite = mixed substrate with a volume ratio of 3:1:1, rake and lightly press to make the seedbed flat, and water thoroughly; in order to control the temperature, humidity and light of the seedbed environment, an arc-shaped plastic shed is built on the seedbed, and the shed is equipped with automatic spraying facilities , A movable sunshade net is set outside the shed; after the seedbed is made, the substrate and surrounding environment are disinfected with a 500-fold carbendazim aqueous solution....

Embodiment 2

[0022] Embodiment 2: the method for Jiangxi rhododendron cutting propagation

[0023] Compared with Example 1, the only difference is that the test material described in "Step 2" is Rhododendron kiangsiense (R.kiangsiense).

[0024] By adopting the method of the invention to propagate Rhododendron Jiangxi by cuttings, the callus formation rate is as high as 100.00%, the rooting rate is 76.67%, and the root width is 1.82cm. See Table 1.

Embodiment 3

[0025] Embodiment 3: the method for lily rhododendron cutting propagation, is characterized in that comprising the following steps:

[0026] 1. Seedbed laying: The seedbed is set in the glass greenhouse and adopts a brick-concrete structure. Reserve one drainage hole every 80cm at the bottom of the seedbed, and lay stones, pebbles, and coarse sand on the bottom layer in turn to increase the drainage and ventilation of the seedbed; install geothermal lines on the coarse sand to increase the ground temperature; then lay thick 8-10cm of peat + perlite + vermiculite = 3:1:1 volume ratio mixed substrate, rake and lightly press the seedbed to make the seedbed flat, water thoroughly; in order to control the temperature, humidity and light of the seedbed environment, build an arc on the seedbed Plastic shed, equipped with automatic spraying facilities inside the shed, and movable sunshade nets outside the shed; after the seedbed is made, the substrate and surrounding environment are d...

Abstract

The invention discloses a cutting propagation method for Rhododendron simsii. The method includes the following steps; using a mixture of peat, perlite and vermiculite as a substrate; acquiring top branches with buds from canopy of plants in autumn or early spring, and cutting the top branches into cutting shoots having the length of 7-9 cm; removing a part of leaves, performing single-face healing treatment on the base of the cutting shoots, and then using 100 mg.L-1 IBA aqueous solution to soak the cutting shoots for 16 hours; instantly performing cuttage after treatment of the cutting shoots, wherein the spacing between rows is 8X8 cm, and the cuttage depth is 2 / 3 of the length of the cutting shoots; and using an automatic intermittent spraying system to supply water and increase the humidity during a rooting period, wherein the temperature is controlled at 15.0-20.0 DEG C, the relative humidity is 85.0-95.0%, and the Rhododendron simsii is sprayed with a bactericide every 14 days. The method can effectively solve the problem that the conventional Subsect. Maddenia Rhododendron simsii cutting propagation method is difficult to root, is low in rooting rate, and is few in root systems; the rooting rate can reach over 90%, and the root systems are developed; and the method is simple to operate, is low in cost, and can be used for industrialization seedling of the Rhododendron simsii.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a rhododendron cutting propagation method. Background technique [0002] Rhododendron generally refers to Rhododendron L. plants in the family Rhododendron, and is one of the three major alpine flowers in the world and one of the top ten traditional Chinese flowers. China is the origin and geographical distribution center of rhododendrons in the world. There are 571 species of native species, of which 34 species are distributed in subsect.Maddenia. Evergreen, with high ornamental value and broad garden application prospects. [0003] Cutting is the main propagation method of small-leaved deciduous and semi-evergreen Rhododendron (Azalea), and it is widely used. However, it is difficult for the large-leaved evergreen Rhododendron native to middle and high mountains to take root from cuttings, and most of them are currently propagated by seeding. Although so...
