Brief introduction to the cultivation of Phalaenopsis

Phalaenopsis, Phalaenopsis, Orchidaceae, Phalaenopsis. It is native to tropical Asia and is distributed in Taiwan, Philippines, Java and other places. There are about 50 species, Phalaenopsis is a single-stem epiphytic orchid with short stems, large leaves, one to several flowering stems, arched and large flowers. The origin of Phalaenopsis is attached to high-temperature and humid rivers and trees near the coast, and is fond of high temperature (suitable temperature 15-30 ℃), humid, ventilated and cool growth environment. The seedlings can not be watered within 2-3 days after transplanting, and the adult plants should be transplanted one month after flowering or 2-3 months before the stem. Spring is the fastest growing period of Phalaenopsis, and it is also the root growth period. It should be kept moist and dry, and should be watered once a day. If you want to cultivate a strong orchid plant, you should let the orchid plant be blown by the appropriate wind. Greenhouse cultivation often leads to poor ventilation, so it is best to put it near a well-ventilated entrance and exit, or use a fan to circulate the air. Organic fertilizer, such as rotten bean cake water, can also be applied with compound fertilizer, or liquid fertilizer diluted 2,000 times every ten days. The sun is strong in summer, it needs to be shaded by 80-90%, and it can be watered once in the morning and evening, and leaf water can be sprinkled even during the day in severe dryness. Since the shading reaches 80-90%, it is more effective to water leaves at night. Fertilization is the same as in spring. If liquid fertilizer is used every 7-10 days, whether the growth between spring and summer is smooth will affect the growth and quantity of flowers, so fertilization between spring and summer is very important. In autumn, when the temperature drops below 20 ℃, the growth of new leaves will become late, and if stimulated by low temperature, the flower stem will grow out of the leaf stem. Due to the drop in air temperature, the drying of water is slow, it is best to wait for the surface of the planting material to dry before watering, and the flower stem does not need to be fertilized during the growing period. In winter, the flower stem continues to grow and enter the flowering period, when the temperature drops below 13 ℃, it should be moved into the greenhouse and keep ventilated, it is best to use fan flow air, winter watering should be completely dry, and should be carried out in the sunny morning, the night temperature is low, should avoid watering in the morning to stay in the leaf center overnight. Leave 3-4 nodes of the flowering stem at the end of the flowering period, and the rest will grow into lateral buds and blossom in summer.
