How to make tulips blossom
Tulips are planted in the natural environment and generally bloom from March to May. In order to make tulips blossom during the Spring Festival, the following technical measures should be taken.
The choice of planting balls: in October, choose disease-free insects, enrich the enlarged bulbs, and remove the brown outer skin.
Disinfection of seed balls: before low temperature treatment, soak in the 800 times solution of 75% chlorothalonil wettable powder for 15-20 minutes, then dry naturally.
Low temperature treatment of bulbs: tulips grown in natural environment have a natural dormancy process. in order to make tulips blossom early in the Spring Festival, they must be treated at low temperature for a period of time. The method of treatment is to push forward the flowering period of the Spring Festival for 3 months, select the seed bulb to promote cultivation, wrap it in clean sandcloth, put it in a foam box, place it in a cold room or freezer, and give it a low temperature of 1 ℃-3 ℃, so that the seed ball can pass vernalization. After 45 days, the seed balls were taken out from the freezer and fertilized to cultivate the soil on the pot. The cultivation soil is required to be loose and breathable, containing more phosphorus and potash fertilizer: use a small basin with a caliber of 20 cm, each basin can grow 4-5 balls. When planting, the top of the bulb is slightly lower than the soil surface.
After planting the ball in the pot, pour water thoroughly, move it into the room, and first put it in a low temperature and semi-shade place. In the first seven days, the temperature is kept at 8 ℃-12 ℃, and then it rises slowly, the temperature is between 15 ℃-20 ℃, and gradually moves to the place where the sunshine is sufficient. During this period, the foliage grows rapidly, it is necessary to keep the basin soil moist, topdressing 2MUE 3 times, it will soon be able to heading and budding. During budding, the temperature should be 20 ℃-23 ℃, not less than 20 ℃. During the whole flowering period, the night temperature is not less than 8 ℃, under this condition, tulips can blossom as scheduled during the Spring Festival.

It is easy to plant tulips in late autumn
At present, it is the season to plant tulips. The method is to pot the big balls that can bloom next year, and then cover the soil to fix the bulbs. The base fertilizer can be mixed with the soil without compaction. The top of the bulb slightly shows the surface of the soil. After filling with enough water, it is buried in the soil together with the basin. The overlying soil is about 20cm. Around early December, dig out the basin, remove the overlying soil, and place the basin in a shady room with a room temperature of about 5 ℃. Undernourishment will occur if the room temperature is too high. Spray water on the leaves to increase the air humidity, wait for budding, put in the sun at noon, this

How to plant tulips
In order to make the ground-borne tulip plants robust, colorful, moderate pedicel length and large flowers, attention must be paid to the selection and preparation of ① planting sites in cultivation. The planting site should be in the shelter from the wind and the sun, and the groundwater level is 50-70 cm. The soil is required to be loose and fertile, so it is necessary to turn the soil deeply, such as if the soil quality is not good, replace the original soil of the planting layer with culture soil, and apply the base fertilizer mixed with rotten organic fertilizer and a little superphosphate. Selection and treatment of ② balls. New bulbs planted must be selected for growth.
