How to make spring orchids bloom
Chunlan is deeply loved by Lanyou for its elegant and refined temperament, but many people encounter the problem of "dumb flowers" during the maintenance process. In order for this gentleman from the mountains to bloom, we need to master the golden rule of "four controls and one requirement", from environmental regulation to daily maintenance. This article will systematically analyze the mystery of spring orchid flowering from light management to age control. 1. Regulation of the flowering environment of spring orchid 1. Precise control of light intensity shows a "golden section" rule for light demand: it is best to receive 20,000 - 30,000 lux of scattered light for 4-6 hours a day. Double-layer sunshade net (shading rate 70%) is needed in summer, and direct morning light can be accepted in winter. The flowerpot can be rotated regularly to ensure that the false bulbs receive light evenly and avoid excessive growth on one side. 2. Coordinated management of temperature and humidity An ideal flowering environment should maintain a day/night temperature difference of 8-10℃, and a vernalization period of 5-10℃ for 40-50 days in winter. The air humidity is controlled between 65-75%, and a hygrometer can be placed in conjunction with a humidifier for adjustment. It is recommended to set up a water pan under the shelf to maintain local microclimate through evaporation. 2. Gold ratio for water and fertilizer management 1. The watering cycle and water quality requirements adopt the "see dry and wet" method. Water thoroughly in 3-5 days in spring and autumn, and spray in the morning and evening in summer. It is recommended to use soft water with pH 5.5 -6.5. Tap water can be dried for 3 days and mixed with 1/5 rainwater. In winter, watering should be carried out in the sunny and warm morning to avoid cold water damaging roots. 2. At the key node of nutrient supply, nitrogen, phosphorus and potassium balanced fertilizers (20-20-20) are applied from March to June, and phosphorus and potassium fertilizers (10-30-20) are added from July. During the flower bud differentiation period, 0.1% potassium dihydrogen phosphate can be sprayed on the leaves, twice a month. Pay attention to applying thin fertilizer frequently, control the concentration at 800-1200 times the liquid, and wash the leaf sheaths with clear water after fertilization. 3. Flower promotion skills and age control 1. Mature plant determination standard Healthy spring orchid must have 4-5 mature leaves and a false bulb diameter of more than 1.5 cm. New seedlings need to accumulate nutrients through 3-5 complete growth cycles. Usually, the seedlings bloom within 5 years, and the flowers can be seen within 3 years. 2. Tips for flower bud induction When the temperature difference between day and night exceeds 10℃ in autumn,"water control and flower promotion" can be carried out: keep the substrate dry (water content 40%) for 3 consecutive weeks, and stimulate the temperature difference of 10℃ in morning and evening. Return to normal management immediately after the flower buds are unearthed to avoid bud loss.
After mastering these essence of conservation, the flowering of spring orchids will no longer be an accident. It is recommended to record growth logs every year and adjust maintenance plans based on plant status. Patiently cultivating for 3-5 years will surely reap the rewards of elegance and fragrance.
