Material preparation: torsion bar and scissors.
1. Prepare 4 red and 1 green torsion bars.
2. Cut three red torsion bars into three equal lengths.
3. Fold each cut red torsion bar in half from the middle.
4. Fold the green torsion bar in half and screw it together.
5. Fix nine red torsion bars with upward openings on the green torsion bar.
6. Turn the nine red torsion bars upwards, so that the tulip is ready.
Brief introduction of tulip:
First, morphological characteristics.
Perennial herbs. Bulbs are conical, about 2-3 cm in diameter, covered with yellow to brown skin on the surface, with 2-5 fleshy scales inside. The stems and leaves are smooth and covered with white powder.
Leaves 3-5, banded-lanceolate to ovate-lanceolate, undulate all over, usually hairy, of which 2-3 are broad basal. Flowers solitary, large, erect cup-shaped, magenta, bright yellow to purplish red, with deep purple spots at the base, 6 perianth segments, free, obovate and oblong, flowering from March to May. Capsule loculicidal with flat seeds.
The second is variety classification.
After long-term cross cultivation by gardeners, there are more than 8,000 varieties in the world. There are about 150 kinds produced in large quantities, among which red, yellow and purple are the most popular.
Dutch Jane Carroll discovered a new variety-Cathay Tulip in 1999. The whole flower is in the shape of a purple feathered parrot.
Tulip varieties can be divided into early flowering varieties and late flowering varieties.
Third, growth habits.
Tulip Tulip originated in coastal areas of China, Central Asia, Turkey and other places. Due to the Mediterranean climate, tulips adapt to the humidity and cold in winter and the dryness and heat in summer. They have the characteristics of dormancy in summer, rooting in autumn and winter, sprouting new buds but not coming out. After low temperature in winter, they begin to swell and grow into stems and leaves in early February of the following year, and bloom from March to April. The suitable temperature for growth and flowering is 15 to 20℃.
During the storage period when the stems and leaves become Yellowstone, the flower buds are differentiated, and the bulbs are dug out of the pot and placed outdoors in cold weather. The optimum temperature for differentiation is 20 ~ 25℃, and the highest temperature should not exceed 28℃.
