In which month does Hanlan blossom? In what month is the cold orchid blooming?

Cold orchid is a terrestrial plant of the genus Orchidaceae. The pseudo-bulb is narrowly ovoid and enclosed in the leaf base. Leaves band-shaped, thinly leathery, dark green, front margin often denticulate. Flowers are often yellowish green with yellowish lips, other colors and strong aromas; petals are often narrowly ovate or ovate-lanceolate; labellum subovate; core column slightly bent forward, with narrow wings on both sides. So when does Hanlan blossom? In what month is the cold orchid blooming?

According to the understanding of Han orchid growers, the florescence of Han orchid is from August to December.

Growing environment

Born under forests, beside valleys or on slightly shaded, moist, stony soil, 400-2400 m above sea level.

Distribution range

China distributes Anhui, Zhejiang, Jiangxi, Fujian, Taiwan, Hunan, Guangdong, Hainan, Guangxi, Sichuan, Guizhou and Yunnan. It is also distributed in southern Japan and the southern tip of the Korean Peninsula. The type specimens are cultivated plants and were collected from Japan.

Reproduction method

Ramet

It can be carried out in both spring and autumn, usually every three years. All plants with dense pseudocorms can be ramified, and at least 5 connected pseudocorms should be preserved in each clump. Irrigation should be reduced before splitting, so that the basin soil is better than. When putting on the basin after ramet, first cover the bottom hole of the basin with broken tiles, then cover with coarse stones, occupy the depth of the basin from 5 to 1, and then put coarse-grained soil and a small amount of fine soil, and then plant it with sandy loam rich in humus. Planting depth to the false bulb just buried in the soil strength, the edge of the basin left 2 cm along the mouth, covered with green cloud grass or fine stones, and finally watered thoroughly, placed in the shade for 10-15 days, keep the soil moist, gradually reduce watering, and carry out normal maintenance.

Sowing seeds

The cold orchid seed is very fine, there is only one underdeveloped embryo in the seed, the germination power is very low, and the seed coat is not easy to absorb water, so it can not germinate by conventional sowing, so it needs to use orchid or artificial medium to supply nutrients in order to germinate. It is best to sow the uncracked fruit, sterilize the surface with 75% alcohol, take out the seed, soak it with 10% sodium hypochlorite for 5-10 minutes, take out and rinse it with sterile water for 3 times, then sow it in a culture flask containing the culture medium, and then place it in a dark culture room. the temperature is kept at about 25C, and then moved to the light after germination to form a protocorm. It takes half a year to a year from sowing to transplanting. Tissue culture has been successful, and this method can be used to propagate where possible.
