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, the phenomenon that "no one has enough to eat".
