What environment does the other shore flower like?
Huanhua has attracted much attention because of its unique growth habits and gorgeous flower appearance. As a typical bulbous plant of the Amaryllidae family, its environmental adaptability directly affects the flowering quality. Mastering the balance of the three elements of light, temperature and soil, and combining with scientific maintenance techniques, can make this autumn blush bloom more brilliantly. Light intensity control techniques for the core growth environment elements of the Paranea japonica flower are ideal for 3-4 hours of scattered light irradiation every day. Direct light in the morning and dusk can be accepted in spring and autumn. In summer, a sunshade net needs to be used to filter 60% of the strong light. When planting in a shady environment or north-facing balcony, it is recommended to turn the direction of the pot every half of the month to avoid distorted growth of the stems and leaves. The temperature gradient management plan follows the principle of "warm winter and cool summer" and maintains an active temperature band of 16-28℃. Double insulation is used during the frost period: the surface is covered with a 5cm pine needle layer + a transparent rain-proof film is erected to allow underground bulbs to survive the winter safely in a-5℃ environment. During high temperature periods in summer, combined with the spray system, local temperatures can be reduced by 3-5 ° C. Key points for refined maintenance operations: substrate ratio and improvement It is recommended to use the golden ratio substrate: 40% humus soil +30% coarse river sand +20% volcanic rock +10% bone meal. Add 5% worm cast to improve the structure when changing pots every year to ensure that the porosity is maintained at 35%-40%. The planting depth is strictly controlled at 2.5 times the bulb diameter. Too deep may lead to rotten balls. During the growth period of the water control cycle, the principle of "see dry, see wet" is maintained, and the topsoil is dried and then watered thoroughly. Progressive water control is used during the dormant period: after the end of flowering, the water supply is reduced by 1/3 per week, and the water is completely cut off after 3 weeks to promote hibernation. In winter, choose noon for watering, and the water temperature needs to be consistent with room temperature. Nutrient supply strategy Apply high-phosphate fertilizer to promote roots during early spring germination period, and use phosphorus-potassium compound fertilizer during flower bud differentiation period. Adopt the principle of "thin fertilizer and frequent application", dilute the standard concentration to 1/2 and apply it every 10 days. It is worth noting that excessive nitrogen fertilizer can cause long leaves to obscure the flower stems.
By simulating the ecological environment of the original forest and cooperating with phased maintenance measures, even novices can cultivate high-quality lotus flowers with straight stems and rich colors. Regular observation of plant status and timely adjustment of management plans can allow this mysterious flower to bloom as scheduled year after year.
