Detailed Explanation of Key Technical Points for Post-Harvest Management of Tulips

1. Main characteristics of cut flowers: the longer the low-temperature forcing cultivation at night, the longer the vase life of the cut flowers.

2. Harvesting and cutting developmental stage: the optimal cutting time for tulips varies by variety. Generally, they are cut when the flower is 1/2 colored. Immediately after cutting, place them in an environment with a temperature of 2°C and a relative humidity of at least 85%.

3. Vase life: short vase life is only 3-4 days, while long is about 5-7 days.

4. Preservative treatment methods: preservative solutions cause the flower stems to elongate too much and have little effect on extending vase life. Therefore, preservative solutions are generally not used.

5. Storage and transport techniques: they can be stored dry (placed horizontally) or wet (placed vertically) at a temperature of 2°C, with the flower heads tightly wrapped in plastic film, but long-term storage is not suitable. Some varieties are harvested together with the bulbs at the green bud stage and can be stored for 2-3 weeks at a temperature of 0°C.

6. Handling methods for retailers and consumers

(1) Recut the flower stems, insert the cut flowers into water 15-20 cm deep, wrap the flower heads in plastic film, and hydrate them at room temperature until the cut flowers are firm.

(2) When cut flowers are stored at a temperature of 2°C, the vase life is the longest.

(3) Arranged flowers should be placed in a cool, windless environment and not near a stove. Tulips are phototropic, so indoor light should be evenly distributed to avoid stem bending.

(4) Do not place tulips and daffodils in the same container, otherwise the life of the tulips will be shortened. Tulips may cause redness and swelling of the skin on the palms, so care should be taken when handling them.
