Seedling raising method for coral trees

Abstract

The invention provides a seedling raising method for coral trees, and belongs to the technical field of planting of coral trees. The seedling raising method for the coral trees comprises the followingsteps: 1) pretreatment: sterilizing coral tree seeds in a potassium permanganate solution at the temperature of 36-38 DEG C; 2) acid etching: carrying out acid etching on the pretreated coral tree seeds by using a mixed concentrated sulfuric acid solution containing diethyl ether; 3) hormone treatment: soaking the coral tree seeds subjected to acid etching in an ethanol solution containing indoleacetic acid and fluorenylmethanol; 4) low-temperature stratification germination acceleration: carrying out wet-cold stratification germination acceleration on coral tree seeds by using 3-5-year-oldpine sawdust; and 5) sowing: after carrying out sterilization and deinsectization treatment on a seedling substrate, sowing seeds, sprouting and growing into seedlings. The seedling raising method forthe coral trees has the beneficial effects that the method is easy to implement, the coral tree seeds in a dormant state can be effectively awakened, growth and development of radicles can be stimulated, sprouting of the radicles can be accelerated, the sprouting rate of the seeds can be increased, sprouting can be accelerated, sprouted seedlings are robust, and the transplanting survival rate ishigh.

Description

technical field

[0001] The invention belongs to the technical field of coral tree planting, and in particular relates to a method for cultivating coral tree seedlings. Background technique

[0002] Coral tree (Viburnum odoratissinum), also known as early grass tree (Guangzhou, Huiyang), straight branches, gray-brown bark, with round lenticels, opposite leaves, oblong or oblanceolate, dark green surface Bright, light green on the back, green all year round. The panicle-like corymbs are terminal, with small white bell-shaped flowers blooming from March to April, which are fragrant; after the flowers fade, the oval fruit is orange-red at first, and then the red gradually changes to purple-black, resembling coral, and has a high ornamental value, so The name was first recorded in the "Illustrated Book of Higher Plants in China". Its branches and leaves can be used as medicine.

[0003] The cultivation methods of coral trees mainly include cutting, sowing and transplanting. The...

Embodiment 1

[0037] The present embodiment provides a kind of seedling raising method of coral tree, specifically comprises the following steps:

[0038] Pretreatment: Select round, plump coral tree seeds that are free from diseases and insect pests, soak them in a potassium permanganate solution with a temperature of 36°C and a concentration of 0.012wt%, stir at a speed of 60r / min, and put them in after the water temperature drops to 20°C Transfer the seeds to clean water, keep stirring for 5 minutes, remove and dry in the air; disinfect the seeds with potassium permanganate solution to kill the pathogenic bacteria on the surface of the seeds and prevent them from polluting and eroding the seeds;

[0039] Acid etching: Dissolve 0.25wt% ether in 95wt% concentrated sulfuric acid to obtain a mixed concentrated sulfuric acid solution, take the pretreated coral tree seeds and put them in the mixed concentrated sulfuric acid solution, etch at room temperature for 0.5h, after the acid etching is ...

Embodiment 2

[0046] A seedling raising method for coral trees, comprising:

[0047] Pretreatment: Take coral tree seeds and disinfect them in potassium permanganate solution at 38°C;

[0048] Acid etching: the pretreated coral tree seeds are acid-etched with concentrated sulfuric acid containing ether;

[0049] Hormone treatment: soak the acid-etched coral tree seeds in an ethanol solution containing indole acetic acid and fluorenemethanol;

[0050] Low-temperature stratification and germination: Coral tree seeds are subjected to wet and cold stratification and germination with 5-year-old pine sawdust;

[0051] Sowing: Seedlings are sown after the seedling substrate is disinfected and dewormed, and germinate and grow into seedlings.

[0052] The pretreatment step is specifically: select round, plump coral tree seeds without pests and diseases, immerse them in a potassium permanganate solution with a temperature of 38°C and a concentration of 0.015wt%, stir at a speed of 120r / min, and wai...
