How to turn seedlings when planting sweet potatoes?

How to turn sweet potato seedlings? Do you turn it in rainy season or dry season? Please also have experience to help introduce because sweet potato is vine herbs, vines are creeping growth, stem nodes in the soil have secondary roots generated. Therefore, the yield of sweet potato is related to potato pieces, and the large yield of potato pieces is high. Moreover, the size of potato pieces is not only related to fat water, but also related to the turning or not turning and turning more or less. Therefore, the planting network sorted out how sweet potatoes need to turn vines and when not to turn vines, the following detailed list for netizens reference. 1. Sweet potato needs to be turned over when there is sufficient water: because there are secondary roots at the stem nodes of sweet potato, the secondary roots can absorb a lot of nutrients and water, so that the nutrition grows vigorously, the vines grow excessively, and the reproductive growth of potato pieces is inhibited, resulting in slow growth of potato pieces. At the same time, under the condition of sufficient water, the secondary roots of sweet potato will also grow small potato pieces, resulting in insufficient nutrients, excessive potato yield and small potato size, resulting in low yield of sweet potato. In this case, sweet potato vines should be turned frequently to control the formation of secondary roots and inhibit excessive growth, thus providing more nutrients for reproductive growth and making potato pieces grow rapidly. Second, in the case of drought and water shortage, sweet potato should be turned less or not: sweet potato vines should be turned less or not, so that secondary roots at stem nodes can be generated, providing more water and nutrients for the growth of sweet potato, which is conducive to plant growth and survival. Otherwise, it is not conducive to the growth and survival of the plant, sweet potato will yield. Sweet potato expansion period topdressing method sweet potato how to fertilize high yield
