The practical exploration of the glass greenhouse in flower seedling cultivation and flower blooming regulation

The glass greenhouse, with its precise environmental control capabilities, has become a core facility for high-end flower seedling cultivation and flower blooming regulation. By precisely managing key factors such as light, temperature, and humidity, it not only enhances the survival rate of seedlings but also enables precise control of flower blooming times, providing technical support for the efficient development of the flower industry. 

During the flower seedling cultivation stage, the advantages of the glass greenhouse are particularly prominent. The high light transmittance of low-iron ultra-white glass ensures that the seedlings receive sufficient light, and the adjustable shading system can prevent the tender seedlings from being damaged by strong light. The intelligent temperature control system adjusts the temperature in stages to meet the cultivation needs of different flower varieties - for example, rose cuttings need a constant temperature environment of 25°C during the day and 18°C at night, while orchid tissue culture seedlings require a stable temperature of around 22°C. At the same time, the humidity control system in the greenhouse operates through mist spraying and ventilation in coordination, maintaining the relative humidity of the air at an ideal range of 60%-80%, effectively reducing the incidence of seedling diseases. Data from a butterfly orchid seedling cultivation base shows that the tissue-cultured seedlings grown in the glass greenhouse have an 95% survival rate, an increase of over 30% compared to traditional greenhouses. 

Flower blooming regulation is another important application of the glass greenhouse in flower production. Through light cycle regulation, the blooming time of flowers can be significantly changed: long-day treatment can prompt chrysanthemums to bloom earlier, while short-day intervention can make fuchsias bloom during the National Day period. Temperature regulation is also crucial, as after 5°C low-temperature treatment for 6 weeks in the glass greenhouse, the blooming time of tulip bulbs can be advanced by 2 months, and the uniformity of the flower stems is significantly improved. For greenhouse roses, by controlling the temperature difference between day and night at around 10°C and increasing the CO₂ concentration to 800 ppm, the blooming period can be extended by 15 days, and the number of flowers per plant can increase by 2-3. 

Practice has shown that the glass greenhouse, by constructing a controllable micro-environment, has achieved the standardization of flower seedling cultivation and the precision of flower blooming regulation. This technical model not only improves the stability of flower production but also enables flexible adjustment of the market entry time according to market demands, creating higher economic benefits for flower farmers and promoting the development of the flower industry towards refinement and efficiency.
