Problems solved by technology

The current planting of purple sweet potatoes has the following disadvantages: using seed potatoes to bury seedlings, and then cutting and planting purple sweet potato seedlings will consume a large amount of seed potatoes, the cost of planting is large, and it takes a lot of work and time; people in order to obtain higher yields However, if a large amount of ordinary inorganic fertilizers are applied, the fertilizer utilization rate is low, and long-term use will cause soil compaction and a decrease in yield; after the purple sweet potato is harvested, a large number of purple sweet potato vines will remain. At present, the reuse of purple sweet potato vines is limited and cannot be fully utilized. its value, resulting in a waste of resources

Embodiment 1

[0028] A high-yield planting method of purple sweet potato, comprising the steps of:

[0029] (1) Purple potato vine treatment:

[0030] A. In the first 4 to 6 days of purple sweet potato harvesting every year, select thick, vigorous, and disease-free purple sweet potato vines, cut each section with a length of 8 to 12 cm, remove the leaves, and reserve 1 to 2 cm long petioles for later use;

[0031] B. Lay the prepared purple sweet potato vine on the ground, spray 800 times of liquid of the treatment agent on its surface by artificial fogging, and dry it naturally for subsequent use;

[0032] C. Put the dried purple sweet potato vines into the cellar, first lay a layer of 5~8cm thick mixed sand on the ground in the cellar, and then lay one layer of purple sweet potato vine and one layer of mixed sand. The thickness of the mixed sand layer is 3.5~4.5cm, the distance between the sweet potato vines is 1~2cm, the thickness of the uppermost mixed sand layer is 15~20cm, the total ...
