Embodiment 1

[0044]On October 26, 2011, ordinary Camellia oleifera seeds were selected, soaked for 2 days, and the light and small particles floating on the water surface were removed. Disinfect with potassium permanganate solution for 5 minutes, pick up and rinse, and store in sand for accelerating germination and cultivating anvils. Choose a flat outdoor open space without stagnant water, first spread a layer of fresh medium-coarse river sand about 10cm thick on the bottom, then spread a layer of seeds, the seeds should not overlap, and finally cover with a layer of fresh medium-coarse river sand about 9cm to 10cm thick , After watering and moisturizing, cover it with a film to keep it warm. The humidity of the river sand should be grasped by hand to form a ball, and it is advisable to loosen it. The entire sand bed should be slightly higher than the ground to prevent water accumulation.

[0045] Choose a plot with relatively flat terrain, good ventilation, sufficient sunlight, and good ...

Embodiment 2

[0048] Rhododendron red camellia short panicle root grafting rapid propagation process is as embodiment 1, on November 20, 2010, the common Camellia oleifera seeds were soaked for 1 day, and the seeds with large particles, plumpness, no mildew and insect damage were selected, and 0.1% Potassium permanganate solution was disinfected for 5 minutes, picked up and rinsed, and then stored in sand to accelerate germination. At the beginning of January of the following year, a shade shed was built, and the shading degree in the shed was 75%. Make the bed in the shed, the height of the seedbed is 10cm, and the width is 100cm. Arrange the seedling-raising containers with the substrate neatly and tightly on the seedbed. The nutritional substrate components and parts by weight of the seedling-raising are: 30 parts of yellow heart soil, 50 parts of retting coco peat, 18 parts of organic fertilizer, and 2 parts of superphosphate The container for raising seedlings is a plastic nutrition b...

Embodiment 3

[0052] On October 26, 2011, soak ordinary Camellia oleifera seeds for 1 day, select seeds that are large, plump, and free from mildew and insect damage, and sterilize them with 0.1% potassium permanganate solution for 5 minutes, pick them up, rinse them, and store them in sand to accelerate germination . At the beginning of December, build a shade shed with a height of 1.8m, covered with a shade net, with a shading degree of 75%, and the shade net around the shed hangs down to about 50cm from the ground. On the flat nursery ground, divide the seedbed and walkway, the height of the seedbed bed is 10cm, the bed width is 100cm~120cm, the bed length depends on the terrain, the walkway is 40cm wide, and the drainage port is opened in the low-lying place; plastic seedling containers are placed on the seedbed, and the container specifications 9 cm in diameter and 13 cm high, the nutrient matrix components and parts by weight for seedling cultivation are: 30 parts of yellow heart soil...

Abstract

The invention discloses a short-spike and root-grafting rapid propagation method for camellia azalea. The short-spike and root-grafting rapid propagation method comprises the following steps: selecting general camellia oleifera seeds, sterilizing the general camellia oleifera seeds with potassium permanganate solution and then carrying out stratification, sprouting and anvil culture; after radicles are 3-4 cm in length, grafting the radicles; selecting one-year branches with strongly-grown crown peripheries, full sprout eyes, no pest and disease damage and half lignification to lignification as scions with the length of 2-3 cm; soaking base parts with a plant growth regulator solution; after the scions are grafted, planting the grafted scions in a container bag filled with nutrient-rich substrate on a seed bed in a sunshelter for culturing; and covering, humidifying, shielding and carrying out standard management to form a high-quality grafted container seedling of the camellia azalea. According to the short-spike and root-grafting rapid propagation method, the grafting is realized at the smooth parts of radicles and the root systems of plants are developed, so that the survival rate and the growth amount of nursery stock can be effectively increased and the culture time of the stock is greatly shortened; and the scions are short, and thus the utilization rate and the propagation coefficient of the scions are improved. The short-spike and root-grafting rapid propagation method has the advantages of convenience for operation, high work efficiency and better economic benefit and social benefit; and according to the method, the scale propagation effect of the camellia azalea stock is ensured.

Description

technical field [0001] The invention belongs to the technical field of asexual rapid propagation of plants, and relates to a method for rapid propagation of rhododendron red camellia by root grafting with short spikes. Background technique [0002] Rhododendron Camellia ( Camellia azalea Wei.) belongs to the genus Camellia of the family Theaceae, is an evergreen small tree, also known as Zhang’s Red Camellia, Rhododendron Leaf Camellia, Rhododendron Tea, Four Seasons Tea, etc. Rhododendron red camellia has excellent characteristics such as long flowering period, many flowers, bright colors, high temperature resistance, suitable for shade and humidity, strong stress resistance, and unique leaf shape. It has extremely high scientific research value, ornamental value and economic value. Market development Broad prospects. The geographical distribution of Rhododendron camellia in the wild state is narrow. According to the current survey, it is only scattered in Ehuangzhang Pro...
