Aristolochia mandshurica
Paphiopedilum prefers warm, semi-overcast and humid environment. Like fertile, humus-rich, well-drained sandy soil. It is cultivated in shade in summer and well-lit in greenhouse in winter. In order to maintain high air humidity, water is sprayed on the plant and the surrounding ground every day. Rarefied liquid fertilizer can be applied after planting for more than 40 days, and the basin can be changed every 2-3 years. Adequate water supply is needed during the growing period, and watering should be controlled during the dormant period and the emergence of new buds.
The suitable temperature for the growth of Aristolochia mandshurica is 18 ℃ 25 ℃, and the suitable temperature for overwintering is about 12 ℃, which should not be lower than 5 ℃. If the temperature is 1 ℃, the leaves will wither and the plants will die. If the temperature is above 20 ℃ for a long time, the flower bud differentiation can not be carried out normally, it is difficult to blossom, and it is easy to rot. There should be proper shade in summer and plenty of light in winter. The cultivation substrate which is fertile and has good drainage and air permeability is required.
