How to raise the latest potted tulips?

Tulips, also known as lotus, grass musk, Dutch, etc., are herbs of the genus Tulip of Liliaceae. They are planted all over the world. The flowers are vigorous and straight, the leaves are elegant and beautiful, and the lotus-like flowers are dignified and lovely. They are called the queen of the world and become a symbol of fashion and internationalization. Let's take a look at how to raise potted tulips.

Growth habits of Tulip

Tulips are native to the alpine areas of Xizang, Iran and Turkey in Xinjiang, China. They are sunny and sheltered, warm and humid in winter and cool and dry in summer. It can grow normally when it is more than 8 ℃, and it can generally withstand the low temperature of ~ 14 ℃. Cold tolerance is very strong, in cold areas, if there is thick snow cover, the bulb can overwinter in the open field, but afraid of hot heat, if the summer comes early, the midsummer is very hot, the bulb is difficult to spend summer after dormancy. It requires slightly acidic sandy loam with rich humus, loose and fertile soil and good drainage, and avoid alkali soil and continuous cropping.

The Propagation method of Tulip

The main results are as follows: 1. After growing in one season, the mother ball planted in that year can produce 1-2 large bulbs and 3-5 small bulbs around it, which can blossom in the same year after big bulbs are planted, and small bulbs can also blossom for 1 ~ 2 years.

2. Sowing: the sowing and propagation of tulips are mostly used to cultivate new varieties. The seeds are harvested before the capsule is ripe and cracked. The seeds are sowed indoors in October, kept moist, germinated in the spring of the following year, and blossomed for about 3-4 years.

How to grow potted tulips?

1. Soil: tulips require both water retention and air permeability, the salinity should not be too high, and the pH value should not be less than 6. The mixture of peat, mature soil and sand at 1:1:1 is better. Loose soil is beneficial to the emergence of young buds and the growth of roots and seedlings. The soil is hardened and sticky, it is difficult to unearth young buds, consumes too much nutrients, the germination rate of bulbs is low, and the flowering of plants is small and irregular.

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

3. Temperature: tulips like cool and afraid of high temperature in the whole growth process, and the growth temperature range is 8-16 ℃. Under natural conditions, in mid-late September, when the temperature is 15: 25 ℃, the tulip bulb begins to take root. At this time, the storage bulb must be stored at 9 ℃ to prevent the bulb from rooting under the basal plate. It is generally planted from late October to late November.

4. Watering: water should be watered thoroughly after tulip planting, so that the soil and seed bulbs can be fully combined to facilitate rooting, water should be properly controlled after budding, when the leaves gradually elongate, water can be sprayed on the leaf surface to increase air humidity, and sufficient water supply should be ensured at bolting and budding stages to promote the full development of flowers and proper water control after flowering.

5. Fertilization: tulips are very sensitive to fertilizer, such as insufficient nitrogen fertilizer, the cotyledons are reduced, the leaves are small and poor, the flower stems are shortened, the flowers are small, the florescence is delayed, and most races have only one leaflet. On the contrary, if the nitrogen fertilizer is sufficient, the reproduction coefficient is obviously increased. The effect of single application of phosphate fertilizer is not obvious, but if it can be mixed with potash fertilizer, it will greatly promote the development of flower stem. When nitrogen fertilizer was mixed with potash fertilizer, the number of medium-sized bulbs increased.

6. Diseases: tulip diseases and insect pests mostly occur in the environment of high temperature and high humidity, including stem rot, soft rot, broken color disease, quenching disease, blind bud, etc., and most of the pests are aphids. Adequate soil disinfection should be carried out before planting, virus-free bulbs should be selected as far as possible, diseased plants should be dug up and destroyed in time, and fungicides should be poured once or twice in the growth process of the greenhouse, so that the effect is better. Good ventilation should be maintained to prevent high temperature and humidity. 3% natural pyrethrum can be sprayed 800 times when aphids occur.
