When is the best time to plant tulips in Liliaceae? When does it usually blossom?

Tulip is a perennial herb of the genus Tulip in Liliaceae, with bulbs. Tulip is widely believed to be native to Turkey and is the national flower of Turkey, the Netherlands, Hungary and other countries. So when is the best time to plant tulips? When does it usually blossom?

When is the best time to plant tulips?

October to November: planting bulbs can be planted in flowerpots with a diameter of 10 to 20 centimeters. The basin bottom cushion is about 3 cm thick, such as charcoal slag, masonry grain, ceramsite and so on as drainage layer, adding loose and fertile neutral soil. Pay attention to the use of new soil, planted lily plants and bulbous flowers of the old soil can not be used to prevent viruses, nematodes and other infections. The diameter of 10-15 cm flowerpot is 1-2 balls per pot, and that of 18-20 cm flowerpot is 3 to 5 balls per pot. When planting, the top of the seed ball is flush with the soil. After planting, put it in the shade for 3 ~ 5 days, pour through the water and put it in a cool outdoor place. When the surface of the basin soil is less than 1 cm, it should be watered.

From December to February of the following year: in the cold season, the flowerpot can be wrapped with foam and put outside in the leeward and sunny place, the root system can grow above 5 ℃. If the basin soil is not dry or watered, it will be watered thoroughly.

March to April: sprouting in March. 15-18 ℃ is the peak period of stem and leaf growth, which should be maintained in the sun. 1 ‰ all-element compound fertilizer is poured once a week. The leaf surface can be sprayed with warm water once or twice a day. After the bud appears, often sprinkle water to the ground around the potted flowers to increase the humidity of the air. It can blossom from April to May.

From May to June: generally, the plant can be discarded after flowering. Mountain areas and plateau areas have unique conditions, you can continue to maintain. In general, for plants that bloom before and after the Spring Festival, there is still a suitable growth period of more than two months after flowering. If you are interested, you can continue to raise them for another year. The method is to cut off the flower head immediately after the flower wilts, retain the pedicel and transfer nutrients to the new bulb. The flowerpot was placed in a place with cool ventilation and sufficient light, and 1 ‰ all-element compound fertilizer solution was poured every 10 days to promote the growth of new bulbs. After wilting, the leaves still need to keep the basin soil moist for about half a month.

From July to September: stop water and fertilizer and let the bulbs dormancy in a cool place. If the bulb is dug up in October, if the diameter of the new bulb is more than 3 cm, it can be re-sown and maintained according to the initial planting bulb management method, and the second flowering is expected in April of the following year.

When do tulips blossom?

The flowering time of tulips varies, some earlier, they bloom at the beginning of March, while the late ones do not bloom until the end of April, and the flowering time is short, usually more than ten days. And the florescence varies according to the latitude of the growing area, generally from late March to early May. And the tulip blossoms around eight o'clock in the morning, so if you want to see it bloom, you have to get up early.

Variety classification

After long-term hybrid cultivation by horticulturists, there are more than 8,000 varieties in the world. About 150 species have been mass-produced, of which red, yellow and purple are the most popular.

A new variety of Cathay Pacific tulips, by Dutch Jan Carlo, was discovered in 1999 that the flower as a whole is in the shape of a dark purple feathered parrot. On March 24, 2014, Chinese first Lady Peng Liyuan was invited by the Dutch royal family to name the new purple parrot-shaped tulip Cathay Pacific. Cathay Pacific endows this purple tulip with a new connotation of world peace, national prosperity and the well-being of the people. Now it has become a national foreign affairs event, large-scale celebration, Chinese and foreign flower show, high-end hall decoration display, as well as high-standard etiquette gift flowers.

The cultivated varieties of tulips can be divided into early flowers and late flowers.

Cultivation techniques of Tulip

Field management

Regulating temperature

The optimum temperature of tulip growing period is 5-20 ℃, the optimum temperature is 15-18 ℃, and the growth temperature of plant should be kept at 0-25 ℃. The growth temperature of tulip root system should be above 5 ℃ and below 14 ℃, especially about 10 ℃. The optimum temperature for flower bud differentiation was 17-23 ℃. When the temperature was more than 35 ℃, flower bud differentiation was inhibited. In addition, tulips have strong cold tolerance, can withstand the low temperature of-35 ℃ in winter, and begin to grow when the temperature is kept above 8 ℃.

Water management

Excessive irrigation must be avoided in the process of cultivation, but more water is required within a week after planting, and it should be watered enough to reduce water demand after germination, especially during flowering. Watering should be "a small amount and many times". If it is too dry, the growth will be significantly delayed. During the growth of tulips, the air humidity should be kept at about 80%.

Light condition

When the bulb germinates, the elongation of the flower bud is inhibited by sunlight. Therefore, it must be deeply planted and moderately shaded to prevent direct sunlight from adversely affecting the growth of the bulb.

Soil and fertilization

The sandy loam is better, and the soil pH is neutral and alkaline. Tulips prefer fertilizer and should be fully fertilized before planting. Generally, dry chicken manure or rotten compost is used as base fertilizer and fully irrigated, and carefully ploughed and raked 2-3 days before planting to ensure that the soil is loose. After two leaves, liquid fertilizer can be applied 1-2 times, compound fertilizer with balanced nitrogen, phosphorus and potassium should be applied 3-4 times a month in peak growing season, fertilizer should be stopped at flowering stage, and liquid fertilizer of 1-2 potassium dihydrogen phosphate or compound fertilizer should be applied after anthesis.

Bulb storage

The storage conditions of the bulb directly affect the flower bud differentiation in the bulb and the flowering time of the plant. After harvest, the bulb should be placed in a ventilated, dry and cool place as far as possible. If it is possible to put the seed bulb in 15-17 ℃ cold storage in the high temperature season from July to August, the seed bulb can develop smoothly and promote its flower bud differentiation and development. If the bulb is placed at a high temperature of more than 35 ℃, the flower bud will abort and develop malformed.

Pest control

The main diseases of tulips are Sclerotinia sclerotiorum, Botrytis cinerea and broken petal disease. First of all, the prevention and control method is to select virus-free seed balls as far as possible, disinfect the soil and seed balls, burn disease balls and diseased plants in time, and then spray 5% benzoate wettable emulsion 2500 times every half a month. The main pests of tulips are aphids and root mites. Aphids are generally sprayed with 1000 times of dimethoate emulsion.
