I. growth measures
1. Check the survival three days after cutting planting, and find that the seedlings are missing or dead, and replenish the seedlings in time. If they survive, you can use some light fertilizer to help them grow.
2. If herbicides are used when planting, there may be no grass. If it is not useful, you need to spray weeds with corresponding herbicides when weeds are exposed. The spraying weather should be carried out on a clear and windless afternoon. In other periods, a small amount of grass can also be pulled out manually, and the seed grass must be pulled out before falling seeds.
3. In order to grow well during the growth period, a certain amount of available nitrogen fertilizer mixed with water can be applied during the slow seedling period, and compound fertilizer can be applied quantitatively every other week during the root expansion period.
4. When there is much rainfall in summer, the plant will flourish when the nutrition and water is sufficient, which is not conducive to the growth of the root tuber, so it is possible to lift the vine once or twice to break some fiber roots and avoid consumption. But you can't turn the seedlings.

Sweet potato likes dry, deep and breathable soil environment, excessive rainfall, too much water, asphyxiation and decay of underground roots, or wood rigidity, resulting in bifurcation. So check whether the ditch is well drained after the heavy rain, sometimes deepen the ditch, dredge the ditch blocked by weeds, and let the stagnant water be discharged quickly. If there is a summer drought, it must be irrigated every day after the sun goes down, must be thoroughly watered, and should not be dry or wet.
