If the water is sufficient, the secondary roots are formed in the sweet potato stem section, because the secondary roots can absorb nutrients and water in a large amount, so that the vegetative growth is strong, the vines grow long, thereby inhibiting reproductive growth, the growth of potato tubers is slow, and the secondary roots grow sweet potatoes. Blocks, resulting in insufficient nutrients, the phenomenon of "everyone is not enough", resulting in low sweet potato production. In this case, the sweet potato vines should be frequently flipped to control the formation of secondary roots, inhibiting the growth, thereby providing more nutrients for reproductive growth and allowing the potato to grow rapidly.

If the soil is dry and lacks water, it is necessary to turn the sweet potato vines less or not, so that the secondary roots at the stem nodes are formed, which provides more water and nutrients for the growth of the plants, which is beneficial to plant growth and survival.
