Detailed Explanation of the Reproductive Characteristics and Growth Habits of the Mountain Lily

(1) Root and bulb characteristics The roots are fleshy roots that grow from the base of the bulb, with no distinction between main and lateral roots, and are also called "basal plate roots." There can be as many as several dozen basal plate roots, which have a strong ability to absorb nutrients in the soil and do not die off the following year. Fibrous roots grow on the upper part of the bulb, called "upper plate roots." The upper plate roots emerge later, are distributed in the surface layer of the soil, and serve to anchor and support the aboveground stem. The upper plate roots die together with the aboveground stem every year. The bulb is in the soil, with its top 3-6 cm from the soil surface, and is composed of scales and a shortened stem. The shortened stem is a conical disk-shaped

The upper plate roots die together with the aboveground stem every year. The bulb is in the soil, with its top 3-6 cm from the soil surface, and is composed of scales and a shortened stem. The shortened stem is a conical disk-shaped body that functions to store nutrients, produce roots, and bear and support the scales. The scales are numerous and overlap in several layers. One mother bulb can divide to produce 3-10 daughter bulbs, and the daughter bulbs are also formed by many small scales clasping together. The aboveground stem is formed by the elongation of the terminal bud of the disk-shaped body.

(2) Requirements for environmental conditions It likes light in the early and middle stages of growth, especially during the budding and flowering period; if the light is weak, the flower buds are prone to dropping. It likes cool conditions and is cold-tolerant. The suitable temperature for growth and development is 15-25°C; if it is higher than 30°C for a long duration, the plant will turn yellow and even die. The seedling stage is not tolerant of frost; when the temperature is below 10°C, growth is inhibited, and below 3°C the leaves suffer frost damage. The bulb is cold-tolerant and can overwinter safely at temperatures of -20 to 40°C. It likes dryness and fears waterlogging; if water accumulates after rain during the growth period and is not drained in time, especially in a high-temperature and high-humidity environment, it often causes the plant to turn yellow and diseases to occur. It is not sensitive to air humidity and can grow normally in both the south and the north. It likes fertile, deep sandy soil. The suitable soil pH is 5.5-6.5.
