How to grow potted tulips?

Tulips are also called foreign lotus, grass musk, Dutch flowers, etc., which are herbs belonging to the genus Tulip of Liliaceae. They are planted all over the world. The flowers are strong and straight, the leaves are elegant and beautiful, and the lotus-like flowers are dignified and moving. They are called the world flowers and become a symbol representing fashion and internationalization. Let's take a look at how potted tulips are raised.

Tulip Growth Habits

Tulip originated in China ** Xizang, Iran and Turkey alpine areas, is a long-day flowers, like sunny, sheltered, warm and humid winter, cool and dry summer climate. It can grow normally above 8℃ and generally can withstand low temperature of ~14℃. Cold resistance is very strong, in cold areas such as thick snow cover, bulbs can winter in the open field, but afraid of heat, if summer comes early, summer is very hot, bulbs difficult to spend summer after dormancy. Requirements humus-rich, loose fertile, good drainage of slightly acidic sandy loam, avoid alkaline earth and continuous cropping.

Tulip breeding methods

1. Bulb division: After a season of growth, the mother bulb planted in the same year of tulip can be divided into 1~2 large bulbs and 3~5 small bulbs at the same time around it. The large bulb can bloom in the same year after planting, and the small bulb can bloom after 1~2 years of cultivation.

2, sowing: Tulip sowing and reproduction, mostly used to cultivate new varieties, seeds harvested before the capsule mature dehiscence, sand storage to October in the indoor pot sowing, keep moist, the next spring before germination, about 3~4 years flowering.

How do potted tulips grow?

1. Soil: Tulip requires both water retention and air permeability for planting soil, salinity should not be too high, nor too acidic, pH value should not be less than 6, and peat, decomposed soil and sand mixed with 1:1:1 as a cultivation substrate is better. Loose soil is conducive to bud emergence, roots and seedlings grow well. The soil is hardened and sticky, the bud is difficult to emerge, the nutrient consumption is too much, the germination rate of the seed ball is low, and the flowering of the plant is small and irregular.

2. Sunshine: Tulips are medium-sunshine plants and like sunny environment. Light is an important limiting factor for tulip flowering. In the cultivation process, tulip must receive no less than 8 hours of light every day, which helps tulip accumulate more photosynthetic products, ensure good plant growth and ensure normal flowering of flowers.

3, temperature: tulips in the whole growth process like cool, afraid of high temperature, growth temperature range of 8~16℃. Under natural circumstances, tulip bulbs begin to take root when the temperature is 15~25℃ in mid-late September. At this time, the storage bulbs must be stored at 9℃ to prevent further rooting under the bulb base plate. Generally, they are planted from late October to late November.

4. Watering: Tulip should be watered thoroughly after planting, so that the soil and seed ball can be fully combined and conducive to rooting. After germination, water should be properly controlled. When the leaves are gradually elongated, water can be sprayed on the leaves to increase the air humidity. During the bolting period and budding period, sufficient water supply should be ensured to promote the full development of flowers. After flowering, water should be properly controlled.

5. Fertilization: Tulip is very sensitive to fertilizer. If nitrogen fertilizer is insufficient, the seed bulb will decrease, the leaf will be small and inferior, the flower stem will be shortened, the flower will be small, the flowering period will be delayed, and most of the small seed bulbs will only grow 1 leaflet. On the contrary, nitrogen fertilizer is sufficient, and the reproduction coefficient is obviously improved. The effect of phosphate fertilizer alone is not obvious. If it can be mixed with potassium fertilizer, it will greatly promote the development of flower stems. When nitrogen and potassium were mixed, the number of medium-sized bulbs increased.

6. Diseases: Tulip diseases and insect pests mostly occur in high temperature and humidity environment. Diseases include stem rot, soft rot, broken color disease, damping-off disease, blind bud, etc. Most pests are aphids. Before planting, conduct sufficient soil disinfection, select virus-free seed balls for cultivation as far as possible, dig out and destroy diseased plants in time when they are found, pour fungicide 1~2 times during the growth of greenhouse, the effect is better, keep good ventilation to prevent high temperature and humidity, and spray 3% natural pyrethroid 800 times when aphids occur.
