Embodiment 1

[0014] Cut the mature sporophylls of Pteridocarpus palmatum and place them on dry filter paper, collect 0.03 g of spores, wrap them with filter paper, and use gibberellin (GA) with a concentration of 10 mg / L 3 ) water solution 10mL soak for 5min.

[0015] Mix the flower soil, plain sand and vegetable garden soil at a volume ratio of 2:1:1 to obtain a soil substrate with a pH of 6.3 to 6.4, sow the spores of Forglena palmatum soaked in gibberellin on the soil substrate, and cultivate at a temperature of 25 to 6.4. 30°C, the light intensity is 2 000-3 000lx, the light time is 11-13h / d, and the humidity is 60%-80%. 20 days after sowing, the spores germinated one after another. After 40 days, the gametophytes developed into lamellar to heart-shaped gametophytes, and after 70 days, the gametophytes developed into mature heart-shaped gametophytes. After 110 days, the gametophytes developed well, and a large number of young sporophytes formed.

[0018] Cut the mature sporophylls of Pteridocarpus palmatum and place them on dry filter paper, collect 0.03 g of spores and wrap them with filter paper, and use gibberellin (GA) with a concentration of 50 mg / L 3 ) water solution 10mL soak for 4min.

[0019] Mix the flower soil, plain sand and vegetable garden soil at a volume ratio of 2:1:1 to obtain a soil substrate with a pH of 6.3 to 6.4, sow the spores of Forglena palmatum soaked in gibberellin on the soil substrate, and cultivate at a temperature of 25 to 6.4. 30°C, the light intensity is 2000-3000lx, the light is 11-13h / d, and the humidity is 60%-80%. 20 days after sowing, the spores germinated one after another. After 40 days, the gametophytes developed into lamellar to heart-shaped gametophytes, and after 70 days, the gametophytes developed into mature heart-shaped gametophytes. After 110 days, the gametophytes developed well, and a large number of young sporophytes formed.

Embodiment 3

[0022] Cut off the mature sporophyll of Pteridocarpus palmatum and place it on dry filter paper, collect 0.03g of spores, wrap the collected spores with filter paper, and use gibberellin (GA) with a concentration of 75mg / L 3 ) water solution 10m soak for about 6min.

[0023] Mix the flower soil, plain sand and vegetable garden soil at a volume ratio of 2:1:1 to obtain a soil substrate with a pH of 6.3 to 6.4, sow the spores of Forglena palmatum soaked in gibberellin on the soil substrate, and cultivate at a temperature of 25 to 6.4. 30°C, the light intensity is 2000-3000lx, the light is 11-13h / d, and the humidity is 60%-80%. 20 days after sowing, the spores germinated one after another.

Abstract

The invention relates to a method for breeding spores of palm-shaped Tectaria subpedata(Harr.)Ching. The method is characterized in that the spores of the palm-shaped Tectaria subpedata(Harr.)Ching are immersed in a gibberellin water solution with the concentration between 10 and 75mg/L for 5min, sowed in a soil substrate with the pH value between 6.3 and 6.4 and cultured in a green house with the temperature between 25 and 30 DEG C, the illumination intensity between 2,000 and 3,000lx, the illumination time between 11 and 13h/d and the humidity between 60 and 80 percent so as to obtain juvenile sporophytes; after the juvenile sporophytes grow 2 to 3 pinnas, the juvenile sporophytes are replanted in the soil substrate with the tray pH value between 6.3 and 6.4 and cultured in the green house with the same conditions. The method of the invention utilizes the characteristics that gibberellin is capable of breaking the dormancy of seeds, tubers and bulbs, etc., to breed the spores of palm-shaped Tectaria subpedata(Harr.)Ching, which effectively shortens the breeding cycle of the spores of palm-shaped Tectaria subpedata(Harr.)Ching, makes the survival ratio of the juvenile sporophytes reach more than 90 percent, facilitates the mass production of palm-shaped Tectaria subpedata(Harr.)Ching and provides technical support for pushing the palm-shaped Tectaria subpedata(Harr.)Ching to flower markets.

Description

technical field [0001] The invention relates to a spore propagation method of ferns, in particular to a spore propagation method capable of rapidly propagating Tectaria subpedata (Harr.) Ching. Background technique [0002] Palmate fern belongs to the genus Pteridophyllaceae. It is a small and medium-sized terrestrial fern. It is distributed in Guangxi and Taiwan, my country. It grows in the shade of limestone and likes a humid environment. Its plant shape is beautiful, and its palm-shaped leaves are tender green and unique. Clear, round sporangia on leaf backs are distinctive. Fern palmatum can be used as landscaping for outdoor gardens, or as a potted plant for indoor viewing. It is an excellent foliage plant and has potential market development value. The natural reproduction of ferns mainly includes asexual reproduction and spore reproduction, but the survival rate of the natural reproduction cycle is not high, and there are few studies on the propagation methods of Pter...
