Embodiment 1

[0012] In late October, cut off the spore-containing leaves of Cyrtomium fortunei J.Sm., blow off the dust and debris attached to both sides of the leaves, and finally put them into a clean petri dish prepared in advance. Put it in a ventilated and cool place to let it dry naturally. Collect the spores scattered on the petri dish, put them into a sulfuric acid paper bag, put them in a desiccator, and store them at 0°C until use. In mid-February, the spores were sowed into the gourd moss (Funaria hysrometrica Hedw.) that was clustered on the shady rocks. Gametophytes could be seen 65 days after the spores were sown, and young sporophytes could be seen on the bryophytes after 105 days. Make the sporophyte grow to 20 days, and transplant together in the flower nursery together with gourd moss.

Embodiment 2

[0014] In mid-October, cut off the spore-containing leaves of Pyrrosia lingua (Thunb.) Farwell, blow off the dust and debris attached to both sides of the leaves, and finally put them into a clean Petri dish prepared in advance. Put it in a ventilated and cool place to let it dry naturally. Collect the spores scattered on the petri dish, put them into a sulfuric acid paper bag, put them in a desiccator, and store them at 4°C until use. Sow the spores to the wall moss (Tortula muralis Hedw.) that grows on the shady rocks in early February in spring. The spores germinate 60 days after sowing and form gametophytes. After 65 days, young sporophytes can be seen on the wall moss , and then the sporophytes were grown to 30 days, and then transplanted together with wall moss in the greenhouse.

Embodiment 3

[0016] In late May, cut off the spore-containing leaves of Osmundajaponica Thunb., blow off the dust and debris attached to both sides of the leaves, and finally put them into a clean petri dish prepared in advance, and place them in a ventilated and cool place. Let it dry naturally. Collect the spores scattered on the petri dish, put them into a sulfuric acid paper bag, put them in a desiccator, and store them at 2°C until use. In mid-March, the spores were sown into the hyacinth mosses clustered on the shaded rocks. The spores germinated 20 days after sowing to form gametophytes, and young sporophytes could be seen on the moss mosses after 90 days. After the sporophyte grows to 30 days, it is transplanted in the flower garden together with the hyacinth moss.

Abstract

The present invention relates to a pteridophyte propagation method in limestone district, belonging to the field of flowers, plants and Chinese medicinal herbs cultivation technology. Said method includes the following steps: collecting spores in spore ripening season of pteridophyte, placing the collected spores into a clean container, placing said container in a ventilating shade place and making it be naturally dried; in 2-3 month of spring sowing the spores into the moss cluster grown on the nightside limestone, after the sporophyte is grown for 20-30 days, transplanting the sporophyte together with moss cluster into green-house or flowers nursery garden to make cultivation.

Description

technical field [0001] The invention relates to the technical field of cultivation of flowers and Chinese medicinal materials, in particular to a method for propagating ferns in limestone areas. Background technique [0002] Ferns are also called ferns, which have obvious generation alternation, asexual reproduction is the production of spores, and sexual reproductive organs include spermatozoa and archegonia. The sporophyte of ferns is far more developed than the gametophyte, and has differentiation of roots, stems, and leaves, and a transport system composed of primitive vascular tissues. Ferns are distinguished from seed plants by producing spores but not seeds. Both sporophytes and gametophytes of ferns can live independently. There are about 12,000 species of ferns growing on the earth, most of which are herbaceous plants. There are more than 2,600 species grown in my country, most of which are distributed in the southwestern region, provinces south of the Yangtze Ri...
