A kind of nursery method of coral tree

Abstract

The invention provides a method for raising coral tree seedlings, which belongs to the technical field of coral tree planting, comprising: 1) pretreatment: taking coral tree seeds and disinfecting them in potassium permanganate solution at 36-38°C; The pretreated coral tree seeds are acid-etched with a mixed concentrated sulfuric acid solution containing ether; 3) Hormone treatment: the acid-etched coral tree seeds are soaked in an ethanol solution containing indole acetic acid and fluorenemethanol; 4) germination by low-temperature stratification : Carry out wet and cold stratification germination to coral tree seeds with 3-5 year old pine sawdust; 5) Sowing: Seedlings are sown after being disinfected and disinfested, and germinate and grow into seedlings. The beneficial effects are: the method is easy to implement, can effectively awaken coral tree seeds in a dormant state, helps to stimulate the growth and development of radicles, accelerates the germination of radicles, improves the germination rate of seeds, accelerates germination, and the germinated seedlings are strong and transplanted. Planted high survival rate.

Description

technical field

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

[0002] Coral tree (Viburnum odoratissinum), also known as Zaohe tree (Guangzhou, Huiyang), straight branches, bark gray-brown, with round lenticels, opposite leaves, oblong or oblanceolate, dark green surface Bright, light green on the back, green all year round. The inflorescences of conical corymbs are terminal, and white bell-shaped flowers bloom between March and April, which are fragrant; after the flowers recede, they show oval fruits, which are orange-red at first, and then gradually change from red to purple-black. It looks like a coral and has a high ornamental value. It is named after it was first recorded in the "Illustrated Book of Higher Plants in China". Its branches and leaves can be used as medicine, which has the effect of clearing the meridians and activating collatera...

Embodiment 1

[0037] The present embodiment provides a method for raising seedlings of a coral tree, which specifically includes the following steps:

[0038] Pretreatment: Select round, plump, and pest-free coral tree seeds, immerse them in potassium permanganate solution with a temperature of 36 °C and a concentration of 0.012 wt%, stir at a speed of 60 r / min, and put the seeds after the water temperature drops to 20 °C. The seeds are transferred to clean water, stirred continuously for 5 minutes, and then taken out to dry; disinfecting the seeds with potassium permanganate solution can 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 into the mixed concentrated sulfuric acid solution, and etch at room temperature for 0.5h. Rinse off the sulfuric acid with...

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

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

[0048] Acid etching: acid etching the pretreated coral tree seeds 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 fluorene methanol;

[0050] Low-temperature stratification germination: Use 5-year-old pine sawdust to germinate coral tree seeds by wet and cold stratification;

[0051] Sowing: Seedling substrates are sterilized and treated with insecticides and then sown, germinate and grow into seedlings.

[0052] The pretreatment step is specifically as follows: selecting mellow, plump, and pest-free coral tree seeds, immersing them in a potassium permanganate solution with a temperature of 38° C. and a concentration of 0.015 wt%, stirring at a speed of 120 r / min, and waiting for...

[0065] Hormone treatment: soak the acid-etched coral tree seeds in an ethanol solution containing indole acetic acid and fluorene methanol;

[0066] Low-temperature stratification germination: 4-year-old pine sawdust is used to germinate coral tree seeds by wet and cold stratification;

[0067] Sowing: Seedling substrates are sterilized and sterilized and then sown, germinate and grow into seedlings;

[0068] Described seedling substrate is the mixture of weakly acidic garden soil, perennial pine needle layer, plant ash and river sand with a volume ratio of 6:3:2:1; using weakly acidic garden soil, perennial pine needle layer, plant ash and river sand as the seedling substrate, both It e...
