When will the wind and rain orchid bloom?
Among the many bulbous plants, Eurysia has attracted much attention for its unique flowering characteristics. This plant, known as "rain lily", always blooms collectively after heavy rains, and the pink and white flowers contrast sharply with the green leaves. This article will deeply analyze the flowering mechanism of ponyweed and reveal its flowering rules and maintenance tips. 1. Natural flowering pattern of Euryopsis chinensis 1.1 Annual flowering time span The flowering period of Euryopsis chinensis spans the three seasons of spring, summer and autumn, and lasts from mid-May to late October. In the warm and humid southern region, it can even last until early November, showing strong flowering endurance. Each mature bulb can bloom 3-5 times a year, and the population flowering period can last for about 7 days. 1.2 Single flower opening characteristics The characteristics of a single stormy orchid blooming during the day and closing at night are particularly unique. This circadian rhythm is closely related to light intensity. The bloom cycle of each flower is 2-3 days, during which it will go through a complete process from the beginning to bloom and then to closure. When it starts to clear after rain, the flower stems will sprout quickly, and preparations for flowering are usually completed within 48 hours after rain. 2. The triggering mechanism for flowering of ponyweed 2.1 Climate factors affect sudden changes in temperature and water stimulation are the main inducements: · 15℃ temperature difference stimulation (cold water irrigation method)·Sudden strong light after continuous cloudy days·Changes in air pressure and water infiltration caused by heavy rain These environmental mutations will cause the bulb to release flowering hormones, forming a unique landscape of "seeing flowers after rain." 2.2 Artificial flower promotion techniques can effectively promote flowers by simulating the natural environment: ·Low-temperature stimulation method: Pour the whole plant thoroughly with cold water at 10-15℃·Light regulation: Suddenly increase light after 15 days of continuous shading·Mechanical stimulation: pruning 1/3 of the leaves induces stress response combined with phosphorus and potassium fertilizer supplementation can increase the success rate of flowering to more than 80%. 3. Key points for year-round maintenance of rainbows 3.1 Regional maintenance differences. Attention should be paid to open-air cultivation in the south: ·Keep the soil slightly moist and no water accumulation·Cover the shade at noon in summer by 30%·No need to pilling in winter to protect potted plants in the north: ·Use pottery pots to ensure ventilation·Keep the wintering temperature above 5℃·Gradually increase the watering amount in spring 3.2 Seed ball reproduction management Mature balls can divide into 3-5 balls every year, and ball reproduction should be carried out in early spring. Pay attention when purchasing seed balls: ·Mature balls with a diameter of>2.5cm·Keep complete root systems·Check that there is no mildew damage. Flowers can be seen 7-10 days after planting the new seed balls, fully reflecting their fast-growing characteristics.
After mastering the flowering rules of rainbows, we can not only appreciate its amazing group blooming effect, but also realize the fun of cultivating flowers through scientific control. This characteristic of blooming in rain is the crystallization of plants 'wisdom to adapt to nature and deserves our careful observation and taste.
