Problems solved by technology

[0005] Still another object of the present invention is to provide a rapid breeding method for Hematoma japonica seedlings, which uses the seeds of Hematoma japonica for tissue culture to obtain seedlings of Hematoma japonica, and transplants the seedlings into the seedbed to continue cultivating to obtain cultivated seedlings of Hematoma japonica. This breeding method can effectively improve the breeding coefficient of S. hemataceae, retain the excellent genetic characteristics of S. hemataceae, the survival rate of seedlings is as high as 90%, and the survival rate of cultivated seedlings is as high as 80%. After transplanting, the seedlings grow well without "little old man". The emergence of the phenomenon of seedlings solves the problem of dwindling wild resources and the difficulty of natural regeneration of the population, which is conducive to the effective protection of this rare and endangered plant.

Embodiment 1

[0052] A method for rapid propagation of pig blood tree cultivated seedlings includes the following steps:

[0053] A. Take mature pig blood tree seeds, soak them in an aqueous solution containing 100g / L milk tree sap at 35°C for 24 hours, take them out, rinse them with linear tap water, and then remove the pig blood tree The seeds were soaked in natural disinfectant for 30 minutes, and finally the porcina seeds were rinsed with sterile water three times and the surface moisture was removed with sterile filter paper to obtain explants, where

[0054] The preparation method of the natural disinfectant is: pulverize 10 parts by weight of Dylan, 8 parts by weight of Melaleuca albicans, 8 parts by weight of Eucalyptus globulus, 7 parts by weight of garlic, 4 parts by weight of lemongrass and 3 parts by weight of cloves to 50 meshes. Add 500 parts by weight of water to soak at room temperature for 1 hour, and then extract at 60°C under vacuum reflux for 2 hours, filter to obtain the fil...

[0104] A method for rapid propagation of pig blood tree cultivated seedlings includes the following steps:

[0105] A. Take mature pig blood tree seeds, soak them in an aqueous solution containing 100g / L milk tree sap at 35°C for 36 hours, then take them out, rinse them with linear tap water, and then remove the pig blood tree The seeds were soaked in natural disinfectant for 30 minutes, and finally the porcina seeds were rinsed with sterile water for 5 times and the surface moisture was removed with sterile filter paper to obtain explants, where

[0106] The preparation method of the natural disinfectant is: pulverize 12 parts by weight, 10 parts by weight of Melaleuca alba, 10 parts by weight of Eucalyptus globulus, 9 parts by weight of garlic, 6 parts by weight of lemongrass and 5 parts by weight of cloves to 100 mesh. Add 500 parts by weight of water to soak at room temperature for 1 hour, then vacuum reflux at 60°C for 4 hours, filter to obtain the filtrate, and then add 18 pa...

Abstract

The invention provides a rapid breeding method of Euryodendron excelsum cultivation seedlings. The method comprises the steps of explant selection and disinfection, aseptic seedling culture, clustered bud induction, rooting culture, seedling strengthening culture and seedbed culture. Compared with traditional seedling growing methods of Euryodendron excelsum, the method provided by the invention has the advantages of small amount of needed Euryodendron excelsum seeds, realization of short-time mass propagation, keeping of excellent hereditary features of Euryodendron excelsum, good quality of seedlings, low malformed seedling rate, high survival rate of the seedlings reaching 90%, high survival rate of cultivated seedlings reaching 80%, good growth vigor of transplanted nursery stocks, no runt seedlings, effective solving of the problems of increasing reduction of wild resources and difficult natural population updating of Euryodendron excelsum, and provision of technical support for effective protection of the rare and endangered plant Euryodendron excelsum.

Description

Technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for rapid propagation of pig blood tree cultivated seedlings. Background technique [0002] Euryodendron excelsum H.T.Chang belongs to the perennial woody plant of the genus Euryodendron excelsum H.T.Chang in the family Theaceae. It is a rare and endangered plant of the unique monotypic genus in my country and has been listed as a national second-level protected plant. Porcina has a special systematic position and is an important material for studying the phylogeny and morphological evolution of Camellia. At the same time, its trunk is straight, the heartwood is beautiful, and the wood is extremely hard. It is an excellent building material and furniture material, and has certain economic value. . At present, Porcina is only distributed in Bajia Town, Yangchun County, Guangdong Province, and only one population remains. There are only more than 100 indi...
