Problems solved by technology

Although there are some reports on the tissue culture and cutting propagation of Hupermus serrata, there is no fundamental solution to the technical problems of rapid propagation of Hupermus serrata large-scale planting seedlings, and the cost of tissue culture seedlings is high, and the propagation coefficient of cuttings is low, so it is difficult to achieve industrialization. Require
It takes 6-7 years for the spores of Huperzia serrata to break dormancy and germinate under natural conditions, and there is no report of successful large-scale reproduction of spores

Embodiment 1

[0019] On October 5, 2 g of mature spores of Huperzia serrata (Thunb.) Trev. were collected and stored at -30°C. Peat is used to make a seedling bed with a width of 60 cm and a thickness of 8 cm, and an equal volume aqueous solution of 0.1 ppm IAA and IBA is used to make the water content of the substrate reach 50%. Take 0.02g of cryopreserved spores and sow them on 1m 2 seedbed. The temperature of the seedbed was controlled at 18°C, the relative air humidity was controlled at 50%, the water holding capacity of the substrate was controlled at 50%, the light intensity was controlled at 500lx, and the number of spores germinated in 173 days was 23879. After the spores germinated, the temperature was controlled at 20°C, the relative air humidity was controlled at 60%, the substrate water holding capacity was controlled at 70%, the light intensity was controlled at 1000lx, and 16954 three-leaf seedlings were formed in 175 days.

example 2

[0021] On October 20, 3 g of mature spores of Huperzia serrata (Thunb.) Trev. were collected and stored at -15°C. Adopt leaf humus to make a seedling raising bed with a width of 65 cm and a thickness of 9 cm, and use 1 ppm IAA and 0.5 ppm IBA aqueous solution to make the water content of the substrate reach 60%. Take 0.01g of cryopreserved spores and sow them on 1m 2 Seedbed. The temperature was controlled at 20°C, the relative air humidity was controlled at 60%, the substrate water holding capacity was controlled at 60%, the light intensity was controlled at 1000 lx, and the number of spores germinated in 168 days was 11089. After germination, the temperature of the seedbed is controlled at 24°C, the relative humidity of the air is controlled at 60%, the water holding capacity of the substrate is controlled at 70%, and the light intensity is controlled at 1000 lx. 8094 three-leaf seedlings can be formed in 178 days.

example 3

[0023] On November 20, 6 g of mature spores of Huperzia serrata (Thunb.) Trev. were collected and stored at a low temperature of 0°C. Use leaf humus to make a seedling bed with a width of 70 cm and a thickness of 10 cm, and use 3 ppm NAA and 1.5 ppm IBA aqueous solution to make the water content of the substrate reach 70%. Take 0.3g of cryopreserved spores and sow them on 1m 2 Seedbed. The temperature was controlled at 22°C, the relative air humidity was controlled at 70%, the substrate water holding capacity was controlled at 70%, the light intensity was controlled at 1500lx, and the number of spores germinated in 155 days was 31453. After the spores germinate, the temperature is controlled at 24°C, the relative air humidity is controlled at 70%, the water holding capacity of the substrate is controlled at 80%, and the light intensity is controlled at 1500lx. 23589 3-leaf seedlings can be formed in 178 days.

Abstract

The invention relates to a Huperzia serrata propagation method, which is characterized by including the steps: a, seed collecting and storage; b, preparing substrate; c, sowing the seeds; and d, seedling management. By the Huperzia serrata propagation method compared with the prior art, spore propagation of Huperzia serrata is achieved. Dormancy of Huperzia serrata spores breaks 5-6 years early. Pore germination rate reaches more than 10%, and seedling emergency percentage reaches more than 70%.

Description

technical field [0001] The invention relates to a method for propagating Huperzia serrata. Background technique [0002] Huperzia serrata (Thunb.) Trev., also known as Serpent Melaleuca Tower, Sanzhi, Serpentine Grass, is a Huperzia Bernh. fern of Huperiaceae Huperiaceae. Scattered in Northeast China, Yangtze River Basin, Fujian, Guangdong, Guangxi, Yunnan and Guizhou. [0003] In 1972, it was reported for the first time in China that Huperzine A, an alkaloid extracted from Huperzine serrata plant, is a drug with high efficiency, low toxicity, reversible and high selectivity to inhibit acetylcholinesterase (AChE). Internationally, Huperzine A has been listed as one of the second-generation acetylcholinesterase inhibitors. Pharmacological effects and clinical studies have shown that huperzine A is particularly effective in treating senile memory loss, early senile dementia, vascular dementia, myasthenia gravis, spatial memory impairment, and mental retardation of adolescent...
