How to sow raw stone flowers
Due to its unique shape, raw stone flowers have become a new favorite in the fleshy world. Sowing and breeding is the core way to cultivate this "gem of life." Mastering scientific sowing technology can not only increase the germination rate, but also allow the plants to grow healthily. The following will explain the entire sowing process step by step. The golden sowing period of the four core elements of sowing is ideal from April to May when the temperature difference between day and night is stable at 15-25℃. At this time, the air humidity of about 60% can promote the absorption and expansion of seeds. The Yangtze River Basin can be extended until mid-May, and temperature control equipment is required for sowing in greenhouses in the north. The recommended gold ratio for smart substrate formula: red jade soil (40%)+ volcanic rock (30%)+ coconut bran (20%)+ rice hull charcoal (10%). The particle diameter is controlled at 1-3mm and requires high temperature steam sterilization before use. The precision sowing operation uses the "double disinfection method": the seeds are soaked in 0.1% potassium permanganate for 20 minutes, and the petri dish is irradiated with ultraviolet light for 30 minutes. When sowing, use toothpicks dipped in water and dished on seeds, maintaining a spacing of 0.5cm. Build a miniature greenhouse with intelligent environmental control: cover it with transparent acrylic plates to maintain 90% humidity, and install LED plant fill light (3000lux). Focus on monitoring the EC value of the substrate and keep it below 0.5mS/cm during the germination period. The "stepped ventilation method" is used after sprouting at key maintenance nodes: ventilated for 1 hour a day in the first week and extended to 3 hours in the second week. The light intensity is gradually increased from 2000lux to 8000lux, and it is combined with calcium and magnesium nutrient solution (EC0.8) to promote lignification.
By accurately controlling temperature, humidity, light intensity and nutrient supply, novices can also cultivate crystal clear raw stone flowers. It is recommended to apply microbial bacterial fertilizer quarterly to obtain a perfect window texture in three years.
