Cultivation methods for purple sweet potatoes

I. Growing environment

Purple sweet potatoes grow best at a temperature of around 23 degrees. They are most suitable for growing in temperate regions. So we should choose a warm and dry environment for planting. Sandy soil is the most suitable for purple sweet potato growth, with good drainage. After choosing the land, prepare the soil and apply fertilizer. Apply an appropriate amount of base fertilizer according to the selected area, mainly decomposed farmyard manure, and plow it into the soil together.

II. Seed selection and sowing

1. When carrying out the work of seed selection, those that are slender, have few roots, and have a relatively smooth appearance are our first choice, for example, Shanchuan Zi.

2. When to sow also depends on the planting region we choose. In areas further south, it is generally around Qingming Festival. Planting is also done row by row, so that purple sweet potatoes will have enough space to grow freely in the later stages.

3. During the sowing process, we should also pay attention to the spacing between them. The distance cannot be too small, otherwise it will hinder their growth, they will not be able to absorb enough nutrients, and growth will stop.

III. Field management

The amount used should be controlled well each time, otherwise the desired effect will not be achieved. Strengthen the prevention of field pests, increase the plants' resistance to pests, and reduce the incidence of disease. At the same time, regular weeding should be carried out to prevent them from growing excessively and competing with purple sweet potatoes for nutrients, which would hinder the normal growth of purple sweet potatoes.

IV. Timely harvest

1. If purple sweet potatoes are not harvested in time, they will rot. When the temperature drops to around 15 degrees, purple sweet potatoes can no longer continue to grow as before. At this point, we should immediately carry out the harvest work, but we should not harvest in windy and rainy weather just to harvest on time.

2. The first step of harvesting is generally to remove the vines on the surface, and then slowly dig them out. Be careful not to cut the sweet potatoes in the ground, because infection through wounds would be bad. This would cause great difficulties for transportation, and the commercial value would also be reduced.
