The Latest Purple Sweet Potato Cultivation Techniques and Methods Tutorial

Purple sweet potato is also called black potato. Many people think that purple sweet potato is a bred variety of sweet potato, but this is not the case. Purple sweet potato not only contains all the nutrients found in sweet potato, but also contains anthocyanins, which sweet potato does not have, making it an anti-cancer crop. Sweet potato can relieve fatigue and resist aging, and has great benefits for human health. So how should we cultivate it? Below, the editor brings you the cultivation methods for purple sweet potato. Let's take a look!

1. Land Selection and Fertilization

Purple sweet potato is a warmth-loving crop. A temperature of around 23 degrees is the most suitable for the growth of purple sweet potato. Therefore, when choosing a planting site, we should select an area with moderate temperature, relatively high and dry terrain, and a good drainage and irrigation system. The soil for planting purple sweet potato must have good fertilizer and water retention, and be fertile and loose in texture, preferably sandy soil. After selecting the land, prepare the soil and apply fertilizer. Apply an appropriate amount of base fertilizer according to the area of the selected land. The base fertilizer should mainly be decomposed farmyard manure, and it should be turned into the soil together with the soil during plowing. After plowing, make field ridges to facilitate the growth of purple sweet potato and later management.

2. Seed Selection and Sowing

Seed selection is very important, because it will determine later growth and yield. When selecting seeds, we should try to choose varieties with long tubers, few fibrous roots, and a good appearance, such as Shanchuan Zi and others. When sowing, determine the planting time according to the planting region. In southern regions, planting is usually done around Qingming Festival. For the planting method, try to choose single-row planting, because this can provide enough growing space for purple sweet potato. It is best to plant on an afternoon with overcast skies, as this helps improve the survival rate of seedlings and promotes recovery after transplanting. During planting, control the planting density well. It must never be too dense, as excessive density will hinder the growth of purple sweet potato, lead to insufficient nutrients in the plant, and affect growth.

3. Field Management

⟦NL>After planting purple sweet potato, what we need to do is wait for it to mature and then carry out good field management. Field management includes watering and fertilizing, pest and disease control, and intertillage and weeding, among other tasks. These tasks are all very important for the growth of purple sweet potato. Water and fertilize at the appropriate times according to the growth conditions of purple sweet potato and weather changes. However, be careful not to overdo either, otherwise the results will be counterproductive. Do a good job in preventing field pests and diseases, strengthen control, and reduce the incidence of pests and diseases. Also observe the amount of weeds in the field. When there are too many, they will compete for the nutrients needed for the growth of purple sweet potato, so weeds should be removed in time to create the best growing environment for purple sweet potato.

4. Timely Harvesting

Timely harvesting is an important factor in ensuring the quality of purple sweet potato. Usually in southern regions around National Day, when the surrounding temperature is below 15 degrees, the enlargement period of purple sweet potato has ended, and the growth of stems and leaves has also stopped. At this time, it should be harvested promptly. Harvesting should not be done in windy or rainy weather. When harvesting, first cut off the purple sweet potato vines, then dig gently to prevent mechanical damage to the purple sweet potato. Wounds are highly prone to infection by pathogens, causing the purple sweet potato to rot. This not only makes storage and transportation impossible, but also reduces the commercial value of purple sweet potato, making it unsellable.
