Tulip Bloom Period and Maintenance Methods
As the main star of the spring courtyard, tulips are highly favored for their elegant posture and rich colors. To achieve continuous viewing effect, one needs to master its biological characteristics and seasonal management focuses. This article systematically sorts out the complete knowledge system from bloom period regulation to daily maintenance.
Key Techniques for Tulip Bloom Period Regulation
Natural Bloom Period Features
Under natural conditions, they bloom once from March to May, with a single plant's bloom period lasting 15-25 days. When the day-night temperature difference is maintained at 8-12℃, the blooming period can reach 60 days. If the temperature exceeds 20℃, the withering process will accelerate. Shading nets can be used to reduce the ambient temperature by 3-5℃ to extend the viewing period.
Artificial Intervention Plan
Cold storage of bulbs can achieve off-season blooming: after 8 weeks of treatment at 5℃, they are planted and will bloom 60-70 days later. Using stepwise cold storage, starting from September, bulbs are thawed in batches, which can continuously provide fresh flowers until the following February.
Key Points of Annual Management for Home Maintenance
Light Control System
In the growing season, it is necessary to ensure 6 hours of direct sunlight per day, and during the bud coloring stage, use gauze curtains to filter strong light. In the summer dormant period, move them to a shady place to avoid bulb rot due to high temperatures.
Accurate Water and Fertilizer Supply
Keep the soil moisture at 60% during the germination period and water thoroughly once a week during the bud formation period. Follow the principle of "frequent application of thin fertilizer", supplementing phosphorus and potassium liquid fertilizer (diluted 1500 times) every 10 days during the leaf expansion period, and applying calcium and magnesium fertilizer once after flowering to promote bulb development.
Bulb Revitalization Technique
After the flowers fade, retain the leaves for photosynthesis and dig up the bulbs after the stems wither naturally. Soak them in carbendazim for 30 minutes, let them dry in the shade, and then wrap them in vermiculite and store them at 5℃ to ensure the quality of the next year's blooms.
Mastering these key technical points can not only extend the single viewing cycle but also achieve the multi-year cyclic use of bulbs. It is recommended to establish a maintenance calendar based on local climate characteristics, regularly check the soil EC value and pH value (ideal range 6.0-7.0), and achieve the annual blooming of tulips through refined management.
