Tulips are often divided into bulbs and seeded for propagation.
After one season of growth, there are many small bulbs around the sown female bulbs. The bulbs are classified according to their sizes and planted separately. The big bulbs bloom earlier. When planted in the same year, they bloom in the same year, and the small bulbs need 1-2 years to bloom.
Sowing propagation is suitable for a large number of planting, mostly for cultivating new varieties. First of all, choose a good seed, you can mix multiple categories to sow. In October, the seeds were planted in an indoor soil basin, covered with plastic film outdoors, and germinated in the next spring. Flowering from March to April.
The room temperature was kept at 0-25 ℃ during plant growth. In bulbous plants, the growth of root system is important. The temperature of tulip root system should be above 5 ℃, below 14 ℃, especially 10 ℃. In addition, tulip has strong cold resistance, and can survive through the winter safely at - 35 ℃.
Do not over water during maintenance. The water demand is wavy in different periods. After planting, there will be more water demand in one week, so it is necessary to irrigate enough water. After germination, especially when flowering, the water demand will be less, so that "a small amount of water is needed many times".
During the growth of tulip, 80% air humidity is suitable, too dry or too wet will affect the plant growth.
In the sunshine, the germination of the seed ball will be inhibited. When planting, the seed ball should be deeply planted and properly shaded to avoid the influence of sunlight on the seed ball.
The storage quality of seed ball directly affects the flowering of tulip. The seed ball should be placed in a ventilated, dry and cool place. If possible, the seed ball can be put into a cold storage at 15-17 ℃.
