The Latest Tulip Planting Techniques and Methods Tutorial
The tulip is a perennial bulbous herbaceous plant of the genus Tulipa in the lily family. In 1997, Shenyang City introduced 23 varieties of Dutch tulips, about 200,000 bulbs, for trial planting. The results showed that tulips grow and develop normally in the Shenyang area, bloom well, and can overwinter safely, with a certain degree of resistance. They can be used for flower beds and potted cultivation, making up for the shortage of early-spring flower varieties in Shenyang and enriching Shenyang's flower varieties. However, because the soil in the Shenyang area is rather clayey, large-scale planting can easily cause bulb degeneration, so the soil should be improved in advance and organic fertilizer applied to promote the reproduction and flowering of new bulbs.
Biological Characteristics of Tulips
Tulips originated in Central Asia and North Africa. The genus has about 150 species, and they are long-day plants. They prefer conditions such as full sunlight, good drainage, and loose, fertile sandy soil rich in humus, and they dislike alkaline soil and continuous cropping. They are generally planted in autumn, overwinter underground, and bloom the following spring from April to May. They are extremely cold-hardy and can withstand low temperatures of -35°C in winter. Tulips that overwinter in the open field can bloom naturally in spring. Tulips are 15-60 cm tall and come in a wide range of flower colors. The flower diameter is 25-60 cm, and most are single-petaled flowers. They can grow when the temperature is above 5°C, and grow best at 10°C-20°C. The growth and development of tulips in northern regions can be divided into three stages:
1. The development period of the root system and daughter bulbs.
2. The period of bud growth, flowering, and seed setting.
3. The period of bulb dormancy and differentiation of daughter bulbs and flower buds. They are generally planted in mid-to-late October, can sprout in late March of the following year, form buds in mid-to-late April, bloom from late April to early May, reach bulb and seed maturity from late May to early June, and enter dormancy in mid-to-late June.
Planting and Management Methods
1. Soil preparation and bed making: At the end of September, plow the soil and make beds 25 cm deep, then spread a 15 cm thick layer of moist leaf mold and disinfect it. In mid-to-late October, sow the bulbs at a plant and row spacing of 15 cm × 15 cm, then cover with soil until level with the ground. After 1 week, spray water once to moisten the soil. Watering should be moderate to prevent root and bulb rot. In early December, the tulips have already rooted underground and entered the winter dormancy period. Water once more with winter water before winter arrives, and after that no cold-protection measures are needed.
2. Fertilizing and watering: After sprouting the following spring, water once with dilute fertilizer solution, and water thoroughly at the same time so that the fertilizer solution is evenly distributed in the soil layer to facilitate root absorption. After the flower stem emerges, apply cake fertilizer solution once a week, spray 0.5% monopotassium phosphate once before flowering, and reduce the frequency of watering after the flowers fade, keeping the soil neither dry nor wet to promote the formation and filling of replacement bulbs. When fertilizing, avoid causing rot by splashing fertilizer solution onto the leaves.
3. Digging and storing bulbs: In mid-June, when the plants turn yellow and wither, dig out the underground bulbs (after 10-15 days, the replacement bulbs and seeds have fully developed and matured). When lifting the bulbs, do not bruise them. Then dry the bulbs in the sun for half a day so that surface moisture fully evaporates and miscellaneous bacteria on the bulb surface are killed. After grading, store them in a cool, ventilated place until autumn planting.
