Phalaenopsis is native to the tropics and subtropics. The orchids are peculiar in shape and variety. They have a long flowering time and elegant appearance. They are deeply loved by families and individuals. With the continuous improvement of people's living standards, their spending power has been continuously enhanced. Northeast and Northwest Territories. However, because the Phalaenopsis is sensitive to environmental changes and the environment changes slightly, the buds and flowers will immediately wither and the leaves turn yellow, so people are generally worried that it is difficult for the family of the orchid orchids to maintain. In fact, Phalaenopsis is cultivated in the north. The difficulties are mainly in the humidity, temperature, watering, fertilization, if we in this cultivation techniques, the northern cultivation of orchids is still relatively easy. 1 Humidity Management Phalaenopsis requires more than 60% humidity in the air, but the air humidity in the north is only 20% to 30%. In some places, it will be even lower. When the air humidity is low, the leaves will lose luster and gradually wilting. even death. The most important means to increase air humidity is to spray water on the foliage. In addition to the leaves, flowering plants can also spray water from the back of the petals, spraying 2 or 3 times per day depending on the weather conditions, and spraying less when the sky is cloudy and the temperature is low. Heart water causes rotten heart, when the temperature is high, spray more properly; the ground needs regular watering or wiping. After heating in winter, the family can use the air humidifier to make up the water. If this condition is not available, add water tray to the radiator. Allow the water to evaporate and increase the humidity, or place the phalaenopsis on the underside of the heated window sill, set a water tray under the basin, but must use something to support the basin, let the drain hole be exposed, so that the root can breathe. 2 temperature regulation Phalaenopsis suitable for growing temperature is about 25 °C, the northern continental monsoon climate is very suitable for the rapid growth of Phalaenopsis in summer, the temperature difference between day and night is conducive to the formation of flowers, although the winter is relatively cold, but the indoor heating, generally can meet Its normal physiological and metabolic needs, and can grow slowly, the most important temperature adjustment period in the north is the outside temperature is low, before the heating is not sent in October to November and after the heating is stopped in April, the conditional family during this period The air conditioner and the small heating device can be used to warm the air. Without this condition, the pots can be placed on the sunny window sill or the coffee table in the daytime, and the warmest room can be reached at night. When suddenly cooling occurs, blankets and quilts can be used for heat preservation. 3 Water and fertilizer management The roots of Phalaenopsis are roots of fleshy roots, and the root environment needs to be moist and air-tight. General information on the introduction of water every 3 days in the summer 1 water, pouring water 1 week in winter, in fact, this is a non-strict argument, watering principle is based on the actual situation to determine the watering time and watering, The water used must be air-dried. Phalaenopsis seedling watering quantity should be less in days but it must be grounded; as the plant grows, the water requirement gradually increases, but it must be drenched at one time; Water can help flower bud differentiation; in April and November when the temperature is the lowest, the water is not easy to evaporate. It is necessary to control the amount of water and prevent rot. The length of the watering interval must be determined according to the degree of drying of the cultivation substrate. When the surface of the cultivation substrate is whitish, it is poured with water once again. In summer, the temperature is high, the interval time should be shorter, and the winter is the opposite. When fertilizing seedlings, nitrogen fertilizer should be used as the main fertilizer, and the concentration should be diluted to a very low level. The middle seedlings should use balanced fertilizers with the same ratio of N, P, and K, and the large seedlings should be dominated by P fertilizers. Fertilizers are best used for special orchid fertilizers. If the market can't buy them, they can use flowers and fertilizers. The family can also use diluted rice water, bean cakes, oil bran, fish meal, etc. to ferment and dilute them. Phalaenopsis hi fertilizer but avoid concentrated fertilizer, the South generally every 1 to 2 weeks application of a fertilizer, the north itself watering interval is long, so each watering is best combined with fertilization, under appropriate circumstances, the application of liquid fertilizer can be completely replaced Watering, but at lower temperatures and flowering, no fertilization is required. 4 The light in the northern part of the light is strong, and Phalaenopsis prefers low light. It is better to put it on the indoor culture. Place it in the usual place to avoid direct sunlight from the sun and cause burns to the leaves. Put it on the sun sill in the summer at noon. A sticky note is placed on the screen or glass. Usually do not pay attention to the sudden change in the growth of the flower environment, the family cultivated orchids are generally very rare pests and diseases, master the above cultivation points, the family will be able to create a beautiful Phalaenopsis flowers.
