Growth characteristics of Lilium davidii
The main results are as follows: (1) the characteristic root of root and bulb is fleshy root, which grows from the bottom of bulb, and there is no difference between main and lateral root, which is also called "lower disk root". There are dozens of roots in the lower root, which has a strong ability to absorb nutrients in the soil and does not die every other year. The fibrous root is produced on the bulb, which is called "upper disk root". The upper root occurs late and distributes on the surface of the soil, which can fix and support the aboveground stem. The upper root dies at the same time as the aboveground stem every year. Bulb in soil, apically 3-6 cm from ground surface, composed of scales and short stems. The shortened stem is a conical disk, which has the function of storing nutrition, forming roots, growing and supporting scales. There are a large number of scales and several layers are overlapped. A female bulb can be divided into 3 to 10 bulbs, and the bulbs are also formed by the embrace of many small scales. The aboveground stem is formed by the elongation of the terminal bud of the disk.
(2) according to the requirements of environmental conditions, light is preferred in the early and middle stages of growth, especially in the budding and flowering stage. if the light is weak, the buds are easy to fall off. Like cool, cold-resistant. The suitable growth and breeding temperature is 15-25 ℃. If it is higher than 30 ℃, the plant will wither and even die for a long time. The seedling stage was not tolerant to frost, the temperature was below 10 ℃, the growth was inhibited, and the leaves below 3 ℃ suffered frost injury. The bulb is cold-resistant and can survive the winter safely with a temperature of-20-40 ℃. Like dryness, afraid of waterlogging, stagnant water after rain during the growth period, not eliminated in time, especially in high temperature and humidity environment often cause plant withering and disease. It is not sensitive to air humidity and can grow normally in the south and north. Like rich and deep sandy soil. The suitable pH value of soil is 5.5-6.5.

How do mountain lilies reproduce
The main results are as follows: (1) the seeds are propagated and harvested in September, dried and threshed in the sun and set aside. In the middle and late April of spring, the seeds were sown on the bed according to 20 cm row spacing, covered with soil 2 cm, slightly suppressed, covered with grass curtain, often watered and moisturized, and removed after emergence. (2) when the bulbs were propagated and harvested, the bulbs on the disease-free plants were collected, soaked in 500 times of carbendazim or carbendazim aqueous solution for 30 minutes, and then sowed according to the row spacing of 20 cm x 5 cm. In a year, some of the bulbs reach the species.

Harvesting, processing and Medical function of Lilium
Harvesting and processing: from September to October, after the stems and leaves of the lily withered, the bulbs were dug, the residual stems and fibrous roots were removed, and the scales were peeled off (the bulbs were cut off and the scales were scattered naturally). Wash the soil and boil it in boiling water or steam it in a cage for 3 minutes. Remove quickly when the edge of the scale is soft, the middle is still alive, or there is a very small crack on the back. If there is any mucus, rinse with clean water, immediately spread it on the Reed mat and dry it thoroughly. In case of cloudy and rainy days, the Kang can be dried, and it needs to be turned over when drying to make it heated evenly. When flipping, hold it up with both hands and turn it over quickly.
