At this time, the orchid should be placed in a warm greenhouse without cold air or a room with better sunlight. No need for too high temperature, the average temperature can reach 5 ℃, and the lowest temperature can be reduced to zero. It is OK to pass through the light of glass and plastic. The bud flower pot should be placed in the place with dark light to keep the bright color, which is subject to the degree of humidity and dryness of the environment. It is better to water once every 10 days in the greenhouse and 7-8 days in the room. It is OK to maintain the balance humidity. When it is too dry, it is OK to spray some water in the morning and evening; no application. Fertilizer; do not do any treatment; avoid direct contact with the outside cold air, and try to maintain a low temperature of 0 ~ 5 ℃.
Place the orchid in a warm greenhouse without cold air or in a sunny room. After the middle of the year, increase the amount of light, maintain the average temperature of 10C, and give more light as much as possible, but put the buds in a dark place to get a bright color. Water once every 10 days in the greenhouse, once a week or five days in the room, maintain a humidity of 65-75%. Spray water in the morning and evening when drying. After the middle of the year, a 3000 times diluted liquid fertilizer will be applied for growth, which is beneficial to growth. One or two times of fungicide will be sprayed in a preventive way to avoid direct contact with the outside cold wind. In the middle of the year, Chinese spring orchid will bloom. The delicate flowers should be cut off early.
Keep orchids in a warm greenhouse without cold air or in a sunny room. Increase the illumination after the middle of the year, and the outside temperature will rise from the first ten days to the last ten days. Therefore, open the skylight or window to cool down properly, and avoid sudden strong light to avoid burning the leaves. Try to give more morning light and increase the frequency of watering, 70% or so is good, two times of dilute liquid fertilizer, flowering plants do not irrigate fertilizer, start to produce diseases and insect pests, spray chemicals periodically once or twice a month, increase the frequency of watering, properly ventilate with the outside world under the condition of keeping humidity, pay attention to ventilation, prevent the temperature from being too high, and start to separate plants in the late ten days.
In April, the climate changes greatly. Do not let orchids directly contact with the outside world. Place them in a place with good sunlight. Pay attention to ventilation, so that the temperature in the day does not exceed 30C. It is better to keep 10C at night. Give sufficient light in the morning. In the afternoon, use bamboo curtain or shading net to properly block the light. It is a period of long flowers. Increase the number of watering, but not too wet. Pay attention to ventilation, and keep 70-80% humidity. Water 2-3 times of diluted fertilizer, pay attention to the occurrence of diseases and insect pests, spray about 2 times of insecticidal and fungicide, fully ventilate, maintain the appropriate temperature, cut off the late blooming spring orchid flower axis, and divide the plants if necessary.
In May, the weather gradually turned warm and the climate became stable. The orchid should be placed in a place with good ventilation and morning light. It can be cultivated outdoors, but it should pay attention to the late frost. No special facilities are needed outdoors, while the indoor ventilation should be kept at no higher than 30C, and the morning light should be fully given to about 10 o'clock. In the afternoon, 50% of the strong light should be blocked. In the vigorous growth period, the number of watering should be increased. It should be noted that the ventilation should not be too wet, and watering should be started before and after sunset, because the spring wind is easy to dry. For the injury of new buds, special attention should be paid to maintain the humidity of about 75%. For the reason of more fertilization and watering for 2-3 times during the growth period, attention should be paid to the occurrence of diseases and insect pests, spraying about 2 times of insecticidal and bactericide. For the increase of watering and watering times, more attention should be paid to ventilation, preventing water accumulation and ending the division. Cut off the flower axis one week after the top flower of one stem of nine flowers blooms.
In June, the temperature is getting higher and higher. The orchid should be placed in a place with good ventilation and good sunshine in the morning. At the beginning of high temperature climate, ventilation facilities and shading facilities should be done well to avoid the sharp rise of temperature. Shading 50% and striped blue shading 75%. Pay attention to drying and watering in the morning and evening. In rainy season, humidification measures are generally unnecessary. Only pay attention to dryness, overwetting is easy to cause diseases and insect pests, and water dilute liquid fertilizer for 2-3 times. Fertilization should be carried out in sunny days and sickly seasons, spraying 2-3 times of bactericide and insecticide, paying special attention to ventilation to avoid excessive humidity in and around the basin. Watering must be carried out in the morning and evening to avoid watering at noon to avoid scorching leaves.
Place the orchid in a place with good ventilation and good sunshine in the morning, pay attention to ventilation and shading to avoid excessive temperature rise, shading 50%, shading 75% of the Striped orchid, pay attention to drying and watering in the morning and evening. Spray 2-3 times of bactericide and insecticide, open all windows, strengthen ventilation, stop watering for about 10 days after rainy season due to flower bud differentiation period, and give sufficient light.
In August, the orchid should be kept at a place with good ventilation and sunshine in the morning. It should be kept at about 30C in the daytime and 20c at night. Shading and ventilation should be used to reduce the high temperature at noon. After 10 a.m., 50% of the speckle flowers need to be shaded. 70-80% of the speckle flowers need to be shaded. They need to be watered and ventilated in the evening. The natural humidity can also be met, but they need to be adjusted to 60-70%. At the high temperature at noon, they should be reduced to the minimum. No fertilizer should be applied. They should be sterilized and insecticidal for 2-3 times, and ventilation should be strengthened. In July, there is no flower bud differentiation of orchids. Stop watering for a week and give sufficient morning light to differentiate it.
Place the orchid in a place with good ventilation and good sunshine in the morning. The external temperature can also meet the requirement of keeping the maximum 28c in the daytime and 18C at night. Give sufficient morning light, and then block the light by 50-60%. Water the surface of basin soil in degrees of dryness. Use absorbent cotton to absorb the water at the base of leaves when it is standing, and keep the humidity of 60-80%. After the middle of September, the weather will be cool. Apply fertilizer in the morning and evening, once or twice a month. The behavior of the prevention of insecticidal, bactericidal 2-3 times a month, strengthen ventilation, after the middle of September, according to needs can be divided.
