What if the white crane taro does not bloom
White crane taro is very popular for its elegant white Buddha spaths, but many flower friends often encounter situations where the plant only grows leaves but does not bloom. To solve this problem, you need to systematically analyze it from three dimensions: growth cycle, maintenance details, and environmental control. This article will provide you with a detailed analysis of the five core flower promotion techniques. 1. Characteristics of the growth cycle of white calico 1.1 The physiological maturity period requires that the rafted seedlings need more than 3 years to grow and accumulate, and it takes 5-6 years for the sown seedlings to reach flowering conditions. Plants that have not reached the physiological maturity stage have insufficient storage of nutrients in the roots. It is recommended to accelerate growth by changing pots regularly (replacing pots with large 5cm diameter every spring). 1.2 Nutrient reserves were monitored and observed for vein thickness and leaf glossiness. During the vigorous growth period, decomposed soybean cake water was applied once a month (dilution ratio 1:50) to make the diameter of the base of the pseudostem more than 1.5 cm before it had the foundation for flowering. 2. Refined maintenance plan 2.1 The humidity control system adopts "immersion management": the humidity of the substrate is maintained at 60%-70% in spring and summer, the basin method is used for maintenance, and the outer container is placed with wet ceramsite. Spray leaf surfaces every morning and evening to maintain air humidity>75%. 2.2 Nutrient supplement strategy During the growth period, N-P-K20 -20-20 balanced fertilizer and seaweed (2000 times liquid) are used alternately every 15 days, and potassium dihydrogen phosphate (800 times liquid) is sprayed on the leaf surface 60 days before bud appearance, combined with root irrigation treatment. 2.3 Light control techniques ensure that 2000-3000lux of scattered light for 6 hours every day, and can be adjusted through a gauze curtain with a shading rate of 50%. Continuous dark periods are crucial for flower bud differentiation, and a complete dark environment is maintained for 14 hours a day starting in autumn. 3. Environmental optimization measures 3.1 Air circulation management Install circulating fans to maintain a wind speed of 0.3m/s per hour, pay special attention to floor ventilation, and use overhead trays to avoid stagnant water causing air roots to rot. Open windows in winter should avoid the windward side of the plant. 3.2 Temperature difference stimulation method maintains the temperature difference between day and night during the flower bud differentiation period, 25-28℃ during the day, and drops to 18-20℃ at night. The temperature difference can be achieved by moving the placement position, and flowering can be effectively induced for 3 weeks.
Through systematic implementation of the above maintenance plan, 95% of healthy white lily taro can sprout within 6-8 months. Special attention should be paid to avoid excessive fertilization, and the EC value should be controlled between 1.2-1.8mS/cm. Cut off residual flowers in time after flowering and retain 15cm pedicels to promote secondary flowering.
