What problems should be paid attention to when turning over sweet potato seedlings?

First, in the case of sufficient water, there are secondary roots at the stem nodes, and the secondary roots can absorb a large amount of nutrients and water, so that the vegetative growth is exuberant, the vines grow excessively, and the reproductive growth is inhibited, and the potato grows slowly. At the same time, the secondary root will also grow small potato pieces, resulting in a lack of nutrients, resulting in "everyone does not have enough to eat" phenomenon, resulting in low sweet potato yield. In this case, sweet potato vines should be turned frequently to control the formation of secondary roots and inhibit overgrowth, so as to provide more nutrients for reproductive growth and make potato pieces grow rapidly. Second, in the case of drought and water shortage, it is necessary to turn the sweet potato vines less or not, so that the secondary roots at the stem nodes can be formed, so as to provide more water and nutrients for plant growth, which is conducive to plant growth and survival. Otherwise, it is not conducive to the growth and survival of plants, and the yield of sweet potatoes will be reduced.
