Phalaenopsis is a perennial herbaceous flower of Orchidaceae. It is native to tropical Asia. It has neither stolons nor pseudobulbs, and its adaptability to climate is poor. The stems are short, about 5 cm to 8 cm in length, and only a few pieces of hypertrophic leaves per plant are stacked alternately on the base of the stem. The white, coarse aerial roots hover or hang below the stem base. From flowering period from January to January of the following year, flower buds are drawn from the leafhoppers, arched, and there are more than ten flowers. If the butterfly dances, each flower can be opened for 2 weeks to 3 weeks. The whole plant can be continuously opened for 60 days to 70 days. . Because of its rich colors, charming flowers, elegant posture, known as "the Queen of orchids" reputation. Phalaenopsis has strict temperature requirements. Its optimum temperature for growth is 20°C to 30°C, it is 35°C above summer, it stops growing below 10°C in winter, it must be insulated, and cold air must not be allowed to blow blue plants directly to avoid chilling; when flower buds differentiate, the temperature Need to be below 18°C, raise the temperature after differentiation, and promote flowering. The cultivated Phalaenopsis can be used in plastic pots or ceramic pots. The plant material can be prepared by mixing fern roots, sphagnum moss, perlite, vermiculite, peat soil, charcoal, broken tiles, etc.; usually the ratio is 40% of pruning fern root, peat soil 20 %, charcoal 20%, perlite or vermiculite 10%, mixed cultivation, the effect is acceptable. It needs scattered light all year round. In the winter, it can give a little artificial light to help it bloom. It needs temperatures of 20°C to 24°C throughout the year. At the same time, when it is required to have high temperatures, it is better to spray more water every day, preferably in the morning. Watering, the water can be completely dry before night, leaves, petioles do not stay in the water overnight, otherwise it is easy to cause disease. In the winter, it is also prone to cold frostbite and even defoliation. This is the focus of cultivation. Phalaenopsis can be used as a base fertilizer with a small amount of slow-release fertilizer, usually 1000- to 2,000-fold water-soluble quick-release fertilizer, sprayed once every 10 days to 15 days. The young plants have a little more nitrogen before flowering, and they need to increase the proportion of phosphorus and potassium near the adult plants. After Xie Xie, it is necessary to top-up compound liquid fertilizer with a ratio of nitrogen to phosphorus of 1:1:1, and then increase the proportion of phosphorus and potassium in autumn.
