Osmunda japonica is distributed in most areas of China, Japan and South Korea, and is commonly found in wet places such as ditches and walls under forests. I like warm, humid and sunny places. I am cold-resistant and drought-tolerant, and I don't have strict requirements for soil. I am suitable for growing in loose and well-drained calcareous soil.
Osmunda japonica is often propagated by spores and can also be divided into plants. For plants full of pots, before sprouting in spring, remove the pots, divide their underground roots into several sections, put them in the shade, collect and sow them in sterilized calcareous substrate after new roots grow, cover them with glass to keep them moist, and gametophyte will appear in about 50 days. Seeding should be divided into plants in time, water and fertilizer management should be strengthened to promote seedling growth.
2 parts of humus soil, 65,438+0 parts of broken bricks or sand, and a small amount of hydrated lime as a potted Guanzhong substrate. According to the size of the pot, a potted plant 1-3 clumps, so that the head of the pot is full, and the appreciation will not be affected by the loose plants. In spring and autumn, it should be placed in a semi-cool place, and in summer, it should be placed in some cool and bright scattered light places to avoid direct sunlight. Water should be sufficient so that the soil is not too dry, and water can be sprayed frequently to moisten it, which is beneficial to growth and keep the leaves bright, otherwise the leaves will be scorched by dryness. Liquid fertilizer or slow-release fertilizer can be applied 1-2 times a month during the growing season.
In winter, in the open field, it won't freeze to death, but the leaves will turn yellow. The following spring, the withered old leaves should be pruned, and the yellow leaves should be pruned after they are released. If potted plants are crowded and affect ventilation, they should be replaced with larger pots.

Leaves are clustered, petioles are hard, up to 40 cm long, and the base is densely scaly; The leaves are once pinnate, with an oval-lanceolate outline, a length of more than 65438 0 meters, a thick leaf axis and a hairless stalk; Feathers are numerous, alternate, sessile, nearly leathery, narrowly linear, 16 ~ 22 cm long, tapering at the top in a tail shape, with the whole edge or slightly wavy; Veins are numerous and dense, extending in parallel, very slender, single or branched, but separated from each other without connection. The sporangium is linear and continuous, located on both sides of the feather axis, and the capsule is linear and hard, opening at the feather axis; Sporangium has stipe, and zona pellucida usually has 20 thickened cells; Spore dichotomous, kidney-shaped or nearly spherical.
Evergreen forest is one of the indicator plants of acid soil, which is distributed near gully flow, around the hole on the Yinshan side and under the forest. Distributed in Guangdong, Guangxi, Hunan, Jiangxi, Fujian and Zhejiang.
Harvest and processing can be carried out all year round. Digging roots, cutting off petioles and fibrous roots, washing and drying; Or cut it into pieces and dry it while it is hot.
Characteristics of medicinal materials This product is rod-shaped, slightly curved, with a length of 15 ~ 30cm and a diameter of 5 ~ 8cm. The surface is covered with hollow petiole residues, which are densely covered with brown scales and brown fibrous roots. Petiole residue is oblate and hard, and the cavity diameter is about 65438±0cm. It's hard, it's hard to break Chop into pieces, the section is uneven, petiole residues, scales and residual fibrous roots can be seen on the outer layer, and the middle part is grayish yellow-brown, slightly silty. A slight breath, a slightly astringent taste. It is best to have uniform strips, few petioles and fibrous roots, and firm quality.
