Orchid flowering time
As a representative of elegant flowers, orchids always bring both visual and spiritual enjoyment when they bloom. However, many flower lovers have found that the orchids that are clearly carefully maintained have not seen the shadow of the flower. In fact, the key to making orchids bloom is to master the growth laws and variety characteristics of the four seasons. This article will take you to reveal the mystery of orchids blooming. Map of flowering time of orchids that are normally opened in all seasons. Jianlan is famous for its long flowering period and continues to bloom from May to December; black orchid displays its appearance in the twelfth lunar month of the cold winter (October to March); spring orchid, as a spring messenger, exudes fragrance from January to March; Cymbids bloom in relay from March to May; cold orchid blooms alone in December to January. By mixing different varieties, uninterrupted flower appreciation can be achieved throughout the year. The secret to prolonging flowering period is to maintain a temperature difference of 8-10℃ between day and night to effectively prolong flowering period. The optimal combination of 16-18℃ at night and 24-26℃ during the day is 16-18℃. Phosphorus and potassium fertilizers (diluted to 2000 times) are applied every week during the bud formation period, and water spray is used instead of watering during the full flowering period, which can extend the flowering period of a single flower by 5-7 days. The temperature and light control rules of the four-season orchid maintenance system maintain the natural temperature of 18-28 ° C in spring and autumn. In summer, a double-layered sunshade net (shading rate of 70%) is used, and in winter it maintains above 12 ° C. Light management follows the principle of "full sunshine in winter and spring, and half shade in summer and autumn" to ensure 4 hours of morning light exposure every day. The ratio of water, fertilizer and gold adopts the "three-look watering method": look at the substrate (the planting stone turns white), look at the leaves (the luster is reduced), and look at the weather (continuous sunny days). Apply a special nutrient solution for orchids (N-P-K=8-12-10) every month during the growing season, and use a solution of 3000 times potassium dihydrogen phosphate during the pregnant bud period. The scientific formula of plant materials recommends mixed substrates: pine bark (40%)+ volcanic stone (30%)+ peanut shells (20%)+ charcoal (10%). When changing pots every year, 1/3 of the old plant material is retained, and decomposed sheep manure particles are added as base fertilizer. The pH value is stable in the range of 5.5-6.0.
From the arrogance of Moran in winter to the brilliance of Jianlan in midsummer, after mastering the growth code of orchids, you can reap surprises in bloom every season. Remember the "three factor control method"-precise control of temperature and light, dynamic adjustment of water and fertilizer, and regular update of plant materials. Your balcony will definitely be transformed into an orchid gardening hall.
