There are two preservation methods for tulip bulbs, one is normal temperature preservation, the other is low temperature preservation.Because of the low temperature in the north, it can be stored at room temperature, wrapped in newspaper, and put in a cool and ventilated place.In the south, the bulbs need to be stored at low temperature, and the temperature is controlled between 4 and 9 degrees Celsius in the refrigerator.
1. Vernalization and disinfection: In order to ensure the healthy growth of seed balls, low temperature treatment is usually needed for a period of time, and disinfection is also needed before sowing.Generally, carbendazim is used for soaking for about 30 minutes.Then drop a few drops of gibberellin, which can promote its germination, take out the seed ball after the outer layer of gray-brown skin to be stripped off.

Good drainage can also reduce the possibility of decay.If you make your own potting soil, you can mix garden soil, rotten leaf soil and sandy soil, which can create good growing conditions.
3. Planting: Prepare a flowerpot of the right size, lay broken tiles on the bottom, and cover it with prepared soil.Put the seed ball upright into it, then start filling soil, fill it up and compact it gently with your hands.If the flowerpot is deep, it can also be a variety of several, but do not put together, 20 cm deep pot three is not a problem, according to the triangle can be placed.
4. Subsequent curing: After the seed balls are buried in the soil, appropriate amount of water should be poured. The water content should not be too much, especially there should be no water accumulation.Put the plant in a well-ventilated place, pay attention to the temperature at the same time, and let it see light properly after germination.When the plant has 3-4 leaves, you can fertilize it, which can promote the growth of branches and leaves.
