The ridge of the field is made after ploughing to facilitate the growth and later management of purple potato.

2. Seed selection and sowing

Seed selection is critical because it determines later growth and yield. When selecting seeds, we try to choose varieties with long French fries, few roots and good appearance, such as mountain purple and so on. When sowing, the planting time is decided according to the planting area, and it is usually planted around Ching Ming Festival in the south. Planting method as far as possible to choose single-row planting, because this can provide enough space for the growth of purple potato. It is best to plant in the afternoon on cloudy days, which helps to improve the survival rate of seedlings and promote slow seedlings. When planting, control the planting density, absolutely not too dense, too dense will lead to purple potato growth hindered, lack of nutrients in the body, affecting the growth.

At this time, it should be harvested in time, and the harvesting weather should not be carried out in a windy and rainy day. When harvesting, first cut off the purple potato vines, and then gently dig to prevent the purple potato from mechanical injury, the appearance of the wound is very easy to cause germs to infect the wound, resulting in purple potato fester.
