2. Introduction to Plants

1. Morphological characteristics: The tuber of yam is cylindrical, up to 1 meter in length, and its cross section is white when dry.Its stem is mostly purplish red, usually dextral growth, no hair on the surface.Some of its leaves are alternate, some are opposite, and a few are trifoliate.The shape of the leaves is changeable, mostly broadly ovate in seedling stage, and will become triangular or hastate when they grow up.Its flowers are spikes, male inflorescences have 2-8, female inflorescences have 1-3, petals have purple-brown spots, generally open in June-September.

3. How to maintain: Yam is fond of light. Long time of light can make its branches and leaves more lush, but it will affect the development of rhizomes, which is not conducive to improving yield. Therefore, it is necessary to control the light time.Its demand for water is not very large, potted plants are generally dry and watered thoroughly, ground planting is suitable for shallow irrigation, do not flood irrigation.In addition, if enough base fertilizer is applied at the time of planting, there is no need for topdressing during the growing period.
