Maintenance and management methods of bougainvillea
As a common tropical flower in South China, Bougainvillea is deeply loved for its gorgeous color and long flowering period. However, many flower lovers often encounter the trouble of flowers dying in a flash during family maintenance, which often hides omissions in maintenance details. Let us explore the core factors that affect flowering through scientific observation and case verification. Four Golden Rules for Home Maintenance Four Seasons Strategies for Light Regulation: Full sunshine maintenance is recommended in spring, autumn and winter, and the average daily light needs to reach 6-8 hours. Special attention should be paid in summer: when the temperature exceeds 35 ° C, a 30% sunshade net should be erected between 11:00 and 15:00. Typical cases show that a nursery in Guangzhou installed light sensors to control the summer light intensity within the range of 35,000 - 45,000 LUX, effectively extending the flowering period of a single flower by 5-7 days. The dynamic balance of water management adopts the "three-stage watering method": the soil moisture is maintained at 40%-60% during the growing period, reduced to 30% during the bud appearing period, and increased to 50% during the full flowering period. Special attention should be paid to newly planted plants that need to be thoroughly watered with root-fixing water for 3 consecutive days, and then transferred to routine maintenance. Experimental data from the Xiamen Botanical Garden show that precise water control can increase the number of flowers by 27%. Precise control of pruning timing. Spring re-pruning retains 3-5 nodes of the main branch to promote germination and flowering of flower branches. Post-flowering pruning should be carried out immediately when petals begin to wilter, retaining 1-2 bud points. A horticulturist in Shenzhen has successfully achieved continuous flowering throughout the year through the "two-time pruning method"(light pruning before flowering to promote branches + heavy pruning after flowering to maintain points). The critical point for temperature regulation is the optimal growth temperature of 22-28℃, and the temperature difference at night is controlled at 5-8℃, which is conducive to flower bud differentiation. Special attention should be paid during the winter: when the temperature is lower than 12℃, the heating device should be activated to maintain the basic temperature of 15℃. Data from the Kunming Flower Research Institute shows that the temperature is stable in the range of 18-25 ° C, and the life of flowers can be extended to more than 20 days. Five major causes of sudden shortening of flowering period 1. Water impact: Flood irrigation in the middle of flowering period causes hypoxia in the roots. Typical cases show that excessive watering can shorten flower life by 60%. Light mutation: Stress reaction caused by sudden change of placement 3. Nutritional imbalance: The imbalance of phosphorus and potassium ratio affects the development of calyx 4. Air circulation: The enclosed environment causes increased ethylene concentration to ripen flowers 5. Mechanical damage: Hidden damage caused by daily touching can significantly extend the viewing period of bougainvillea through systematic optimization of maintenance plans and real-time monitoring of environmental parameters. It is recommended that flower lovers establish a maintenance log to record key data such as temperature, humidity, and fertilization cycle, and gradually form a personalized maintenance system.
