How to grow sweet potatoes

1, soil preparation and fertilization

Sweet potato should be planted in spring with suitable climate and environment. Before planting, soil preparation and fertilization should be carried out, and the soil should be deeply plowed and raked, and then furrowed and ridged. Pay attention to the ridge spacing of 80 cm and the ridge height of 20 cm, and apply organic compound fertilizer as base fertilizer in the soil.

2. Transplanting

After the sweet potato grows 3-4 leaves, take it out of the seedling tray, pay attention to retaining part of the soil at the root, use fertile and loose soil to carry the seedlings, then water the root once and apply a thin decomposed farmyard manure once.

3. Post maintenance

In order to facilitate the late harvest of sweet potato and avoid unnecessary nutrient consumption, it is necessary to arrange the plants along the seedlings, arrange the sweet potato vines in the soil in one direction, so that the plants grow in the same direction, and remove the branches and leaves that are too dense, too weak and too long when arranging seedlings to reduce nutrient consumption.
