How to raise chrysanthemum seedlings
As a famous traditional flower in China, the maintenance of chrysanthemum during its seedling stage directly affects the quality of later flowering. Mastering scientific cultivation methods and choosing the best planting season are the key to creating a gorgeous chrysanthemum garden. This paper systematically analyzes the complete knowledge system of chrysanthemum seedlings from daily maintenance to season selection. Scientific cultivation method of chrysanthemum seedlings, light management strategy, light needs to be scattered every day for 4-6 hours during the seedling period. It can be maintained in full sunshine in spring and autumn. In summer, sunshade nets are needed for protection. Insufficient light will cause stems to grow excessively. It is recommended to rotate the flowerpot 180° every 3 days to ensure uniform light reception. Temperature and humidity control points are to maintain the day temperature of 20-25℃/night temperature of 15-18℃, and ventilation needs to be strengthened above 30℃. Use a substrate hygrometer to monitor, maintain the soil moisture content at 60%-70%, and use spray humidification when the air humidity is 50%-60%. Collaborative management of water and fertilizer follows the principle of "seeing dry, seeing wet". Water is permeable every time in spring and autumn, and leaf spray once in the morning and evening in summer. Use N-P-K=15-15- 15 slow-release fertilizer and 0.1% potassium dihydrogen phosphate foliar fertilizer every half month to promote root development. Analysis of the best planting time for chrysanthemums in spring planting advantages Before and after Qingming Festival (the average daily temperature is stable at 15℃), you can make full use of the growing season. Choose to transplant on cloudy days or in the evening, keep the original soil balls, and keep the planting depth so that the junction of roots and roots is level with the soil surface. Autumn cultivation characteristics Plant from late September to early October, and two-year-old strong seedlings are required. After planting, a small arch shed was built to prevent frost, keep the ground temperature above 10℃, and increase the application of phosphorus and potassium fertilizers to enhance cold resistance.
By accurately controlling light, temperature, humidity, and water and fertilizer ratio, combined with scientific planting plans in spring and autumn, the survival rate of chrysanthemum seedlings can reach more than 95%. It is recommended to record growth data every 10 days after planting and adjust maintenance strategies in a timely manner to lay a solid foundation for golden autumn bloom.
