Embodiment 1

[0027] A method for rapidly growing seedlings out of a rhododendron by hard branch cuttings, the described dongjuan is dongjuan "rouge honey", comprising the following steps:

[0028] 1. Seedbed laying: The seedbed is set in a glass greenhouse or a plastic greenhouse. The edge of the bed is made of red bricks or cement bricks. One drainage hole is reserved every 100cm at the bottom of the seedbed, and then stones, pebbles, and coarse sand are added sequentially from bottom to top. In order to increase the drainage and ventilation of the seedbed; lay a 10-15cm thick cultivation substrate on the coarse sand, rake and lightly press the seedbed to make the seedbed flat, and water it thoroughly; in order to control the temperature, humidity and light of the seedbed environment, build an arc-shaped plastic shed on the seedbed , The shed is equipped with automatic spraying facilities, and a sunshade net is set up at 30cm above the plastic shed; after the seedbed is made, the substrate...

Embodiment 2

[0034] Example 2 (comparative example) The experimental material is Dongjuan "rouge honey"

[0035] 1. Seedbed laying: The seedbed is set in the glass greenhouse and adopts a brick-concrete structure. Reserve one drainage hole every 100cm at the bottom of the seedbed, lay stones, pebbles, and coarse sand on the bottom layer in order from bottom to top to increase the drainage and ventilation of the seedbed; then lay peat + perlite + vermiculite with a thickness of 10-15cm = 3:1:1 volume ratio of mixed substrate or plain loam, 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, a curved 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 500 times carbendazim aqueous solution.

Abstract

The invention discloses a rapid seedling propagation method of azalea hardwood cuttings and belongs to the technical field of plant propagation. The rapid seedling propagation method of the azalea hardwood cuttings includes the steps that lignified branches from previous year are collected in June or July; sub-branches on the top end of the lignified branches are transitional branches from semi-lignified to lignified branches in current year; 2 to 5 new branches on the sub-branches and born in the current year act as cutting branches; rooting agent is used for soaking the cutting branches after callus treatment; maintenance and nutrient management and then post-transplant management are conducted. The rapid seedling propagation method of the azalea hardwood cuttings has the advantages of capability of enabling the azalea cuttings seedlings to become independent new plants in the current year and transplanted to be nutritional seedlings for nursery the second year, simple and easy method, low cost and application of industrialized nursery of azalea.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for rapid growth of seedlings and emergence of rhododendron hardwood cuttings. 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 Rhododendron in the world. There are 571 species of native species. Its beautiful plant shape, colorful flowers, high ornamental value and broad market application prospects are widely used in garden engineering. [0003] Cutting is the main propagation method of deciduous, semi-evergreen and evergreen Rhododendron (Azalea), and is widely used, but it is difficult to take root from Rhododendron cuttings, and the growth of cuttings is slow after transplanting. Therefore, in view of the large d...
