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...

The rooting agent in the inventive method is limited to the quick-acting application, and the physiological effect of the rooting agent cannot be brought into play for a long time

[0004] The prior art has application number 2011102114605 and a Chinese patent titled "A Method for Stratification and Germination Acceleration of Ilex Ilex" disclosing that the seeds of Ilex radix L. are directly mixed with wet sand from October to November and then dried in the shade outdoors for stratification. From October to November of the following year, the seeds are taken out and sowed in the hotbed, so that some of the seeds will germinate in white. Although the time required for this method is shorter than the dormancy time of holly, it still takes more than one year.

[0005] The prior art has a Chinese patent with the application number 2013105089873 and the title of the invention "a method for growing seedlings of holly holly". In this patent, the seeds are first soaked in warm water and then treated at low temperature for 15-20 hours, then soaked in potassium permanganate, and then soaked in potassium permanganate. Soak in the mixed solution, and finally after soaking in clear water, put it in the sand bed for germination, but this invention does not disclose the time from the sand bed germination to the seedling growth
