Problems solved by technology

[0003] Rhododendrons are widely distributed in my country. Cutting propagation is mainly used in the planting process. Seed propagation is required when breeding new varieties, but the seeds germinate slowly. It takes 5 to 7 weeks to germinate after sowing, and the germination rate is low, only reaching 75%. left and right, resulting in low planting efficiency, so it is necessary to germinate the seeds of Rhododendron

Embodiment 1

[0016] A method for accelerating germination of rhododendron seeds, comprising the following steps:

[0017] (1) Soaking and softening: Select mature, plump and complete rhododendron seeds, place them in an edible alkali solution with a mass fraction of 1.6%, soak for 80 minutes at 12-14°C, and soak at low temperature to initially soften the seed coat and weaken dormant substances For activity, the seeds have to be soaked;

[0018] (2) High temperature treatment: put the soaked seeds in a constant temperature box at 42°C, with a light of 400 lx, and heat for 30 minutes to simulate the high and low temperature process of the environment, further break dormancy, promote germ activity, accelerate germination, and obtain high temperature seeds;

[0019] (3) Seed dressing activation: add seed dressing agent to high temperature seeds, the weight of the seed dressing agent is about twice the weight of high temperature seeds, provide small molecule nutrients, antibacterial and insecti...

Embodiment 2

[0025] A method for accelerating germination of rhododendron seeds, comprising the following steps:

[0026] (1) Soaking and softening: Select mature, plump and complete rhododendron seeds, place them in an edible alkali solution with a mass fraction of 1.7%, soak for 85 minutes at 12-14°C, and soak at low temperature to initially soften the seed coat and weaken dormant substances For activity, the seeds have to be soaked;

[0027] (2) High temperature treatment: put the soaked seeds in a constant temperature box at 43°C, light at 450lx, heat for 35 minutes, simulate the high and low temperature process of the environment, further break dormancy, promote germ activity, accelerate germination, and obtain high temperature seeds;

[0028] (3) Seed dressing activation: add seed dressing agent to high temperature seeds, the weight of the seed dressing agent is about twice the weight of high temperature seeds, provide small molecule nutrients, antibacterial and insecticide, kill pat...

Embodiment 3

[0034] A method for accelerating germination of rhododendron seeds, comprising the following steps:

[0035] (1) Soaking and softening: Select mature, plump and complete rhododendron seeds, place them in an edible alkali solution with a mass fraction of 1.8%, soak for 90 minutes at 12-14°C, and soak at low temperature to initially soften the seed coat and weaken dormant substances For activity, the seeds have to be soaked;

[0036] (2) High temperature treatment: put the soaked seeds in a constant temperature box at 44°C, with a light of 500 lx, and keep warm for 40 minutes to simulate the high and low temperature process of the environment, further break dormancy, promote germ activity, accelerate germination, and obtain high temperature seeds;

[0037] (3) Seed dressing activation: add seed dressing agent to high temperature seeds, the weight of seed dressing agent is about 3 times the weight of high temperature seeds, provide small molecular nutrients, antibacterial and ins...

Abstract

The invention mainly relates to the technical field of planting and discloses a germination accelerating method of rhododendron seeds. The method comprises the steps of soaking and softening, treating under high temperature, dressing seeds and activating, catalyzing and germinating. The method is simple; the germination accelerating rate is 99%; the germination time is shortened to 3-4 days; the planting survival rate reaches 97%; the economic income is increased by 14.2%. The method is characterized by comprising the following steps: putting rhododendron seeds in a dietary alkali solution for soaking under a low temperature, preliminarily softening seed peels, and reducing activity of dormancy substance; carrying out high-temperature light treatment, simulating the high-temperature process and the low-temperature process of the environment, further breaking dormancy, accelerating activity of germs, and accelerating germination; preparing a seed dressing agent through fermentation, wherein the seed dressing agent is rich in fermentation products, is capable of providing small-molecular nutrients needed for the growth of the germs after dressing seeds, and is also capable of resisting bacteria, killing insects, killing pathogenic microorganisms, breaking dormancy, and accelerating germination of the rhododendron seeds; regulating light, temperature and humidity during germination, accelerating growth of the germs, shortening catalyzing time and improving the planting efficiency.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a method for accelerating germination of rhododendron seeds. Background technique [0002] Rhododendron, also known as azalea, pomegranate, and azalea, is one of the top ten traditional famous flowers in China. Rhododendron not only has great Ornamental value, also has good medicinal value, can eliminate phlegm and relieve cough, antibacterial and anti-inflammatory, lower blood pressure and diuresis, sedative and analgesic. [0003] Rhododendrons are widely distributed in my country. Cutting propagation is mainly used in the planting process. Seed propagation is required when breeding new varieties, but the seeds germinate slowly. It takes 5 to 7 weeks to germinate after sowing, and the germination rate is low, only reaching 75%. Left and right, resulting in low planting efficiency, so it is necessary to germinate the seeds of Rhododendron. Contents of the invention ...
