Published: 2024-11-06 Author: mysheen
Last Updated: 2024/11/06, 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 shortening stem is a conical disk.

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.
