Tulip Blooming Period
As one of the most popular flowers in spring, tulips attract numerous gardening enthusiasts with their elegant posture and rich colors. Mastering the blooming period regulation technology can not only extend the viewing period but also achieve off-season blooming, breaking through the laws of nature.
Principles of Tulip Blooming Period Regulation
Temperature Sequence Control Method
Achieve annual blooming through three-stage temperature regulation: 34℃ high temperature treatment for 7 days in summer → 17℃ constant temperature cultivation for 60 days to complete bud differentiation → planting in September and blooming in December. If an additional 9℃ cold treatment for 7 days is added after differentiation, the blooming period can be extended to the following February.
Fine Maintenance of Tulip Blooming Period
Accurate Temperature Control
Maintain a golden temperature range of 17-23℃ during the bud differentiation period, with a day-night temperature difference controlled within 5℃. When the ambient temperature exceeds 35℃, use sunshades combined with a misting cooling system to prevent high temperatures from burning the bulbs.
Dynamic Light Management
Implement a stepped shading method during the germination period: maintain a 75% shading rate for the first two weeks, and reduce it to 50% in the third week. Use deep planting techniques (8-10cm of soil coverage) combined with black plastic mulch coverage to double the suppression of apical growth advantage.
Scientific Water Supply
Use immersive irrigation during the bud formation period, keeping the soil moisture between 45%-50%. Equip with an EC value tester, and immediately perform leaching treatment when the matrix conductivity is >1.2mS/cm to prevent salt accumulation.
Nutrition Cycle Management
Stop using nitrogen fertilizer during the bud coloring stage and increase the application of phosphorus and potassium fertilizers (N:P:K=5:15:30). After flowering, apply compound fertilizers containing calcium and magnesium elements, combined with seaweed extracts to promote bulb expansion and store energy for the next year's flowering.
The biological characteristics of tulips make them a typical representative of temperature-controlled flowers. By establishing a temperature-light-water-fertilizer integrated control system and managing the bulb dormancy period, it is possible to achieve a continuous blooming period from New Year's Day to Mother's Day (G-Y). This precise regulation technology is driving the innovation of the annual flower market, allowing more people to enjoy the graceful posture of tulips in different seasons.
