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...

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
