African pansy breeding method
Known as the "Queen of Indoor Blooming", African pansy is deeply loved by gardening enthusiasts for its petite plant type and continuous flowering characteristics. This ornamental plant, native to the tropical mountains of Africa, can bloom all year round through scientific maintenance, but it must master its unique growth habits to show the best ornamental effects. Four factors analysis of light control strategies for African pansy cultivation In a scattered light environment of 2000-3000lux, the leaves of African pansy will appear healthy dark green. It is recommended to use a double-layered sunshade net to adjust the light, maintaining 75% shading rate in spring and summer, and adjusting it to 50% in autumn and winter. Special attention should be paid to the strong light at noon that can cause burns to the leaves. You can set up gauze curtains beside the window to filter the light. Precise management of temperature and humidity and maintaining the temperature difference between day and night of 8 ° C can promote flower bud differentiation. It is recommended to control the temperature at night at 18±2℃ and maintain it at 24±2℃ during the day. Use an ultrasonic humidifier to stabilize the air humidity at 60-70%. Special attention should be paid to avoid water droplets directly contacting the fluff on the leaves. The scientific water supply plan adopts bottom infiltration irrigation method to avoid water accumulation in the heart of the leaves. The water content of the substrate is controlled within the range of 30-40%. In summer, 200ml of water is replenished every 3 days and extended to 5 days in winter. When the bottom leaves wilted slightly, the best time to replenish water is. 20-20-20-20-20 water-soluble fertilizer is used for a long time in the nutrient supply cycle, and the concentration is controlled at 800-1000 times the liquid. Switch to 10-30-20 high-phosphorus formula during the budding period, and apply chelated trace elements. It is recommended to adopt the "three waters and one fertilizer" system, that is, add nutrient solution every three times after watering. The disease prevention system for key points of advanced maintenance uses carbendazim and mancozeb monthly for preventive disinfection. If early symptoms of root rot are found, immediately replace the sterile substrate and use hymoxazole to irrigate the roots. Maintaining good ventilation can effectively prevent the occurrence of gray mold. Flowering control techniques can induce flowering through photoperiod control and give 14 hours of darkness every day for 6 weeks. Combined with foliar spraying of 50ppm gibberellin solution can significantly increase the number of inflorescences. Cutting off residual flowers in time after flowering can save nutrient consumption.
After mastering these maintenance tips, African pansy will become the most lasting flowering landscape on your window sill. Regularly observe the status of the plants and adjust the maintenance plan in a timely manner, and coordinate with appropriate variety selection, even novice gardeners can reap the surprises of growing flowers.
