① transplantation. The culture soil for transplanting was prepared with 60% rotten leaf soil, 20% garden soil and 20% bran ash. After the culture soil is loaded into the basin, scrape it flat with a small board, first poke a small hole in the basin soil with a bamboo stick, and then gently insert the young fleshy root of the seedling into the culture soil to bury the rhizome and expose the bulb overnight. When planting, pay attention to the consistent orientation of the leaves, and the seedlings will be wiped out in order to facilitate management in the future.

② temperature, seedling temperature is controlled at 10 ℃ ~ 25 ℃. In the early spring and late autumn, we should fully receive the light. Avoid direct sunlight in summer and put it in a cool and ventilated place.

③ fertilization. After 2 weeks of potting, 15% thin rotten cake (rotten fish and shrimp) should be applied once a week. If a small amount of bone meal is added as base fertilizer, the effect will be better. Do not pollute the leaves or enter the false bulb when fertilizing, and spray clear water after fertilization, commonly known as returning water.

④ watering. The seedlings should be fully watered for the first time after transplanting and keep moist afterwards. When the second leaf of the seedling has not yet grown, the plant should be properly "watered" to reduce and control the amount of water and times of watering, but the leaf should be sprayed at noon. Spray continuously for 2 weeks and give about 20 ℃ of normal water every day. As long as we pay attention to screening seedlings, changing pots in time, strengthening the management of fertilizer and water at seedling stage, adjusting and controlling the requirements of temperature and light in different stages, we can grow more than 10 leaves in 3 years and blossom in the fourth spring.
