The yam has sprouted and can be planted in the soil. When planting, break the germinated yam into several sections, ensure that each section has a germination point, apply plant ash appropriately, and dry it in the shade. Prepare loose and fertile soil in advance, put the soil balance on the soil surface and cover it with a thin layer of soil. Yam should keep astigmatism, shade from the light when it is too strong, and set up a climbing frame in time to let yam vines grow.
