Embodiment 1

[0024] (1) Seed selection: The selection of purple sweet potatoes requires the characteristics of this variety, no pests and diseases, no rot, good quality, and the size of the potato pieces is 100g;

[0025] (2) Cultivate potato seedlings: The method of cultivating purple potato seedlings should adopt greenhouse + small arched shed + 3 layers of plastic film for heat preservation and seedling cultivation to increase the number of seedlings. The width of the seedbed is 10m, and the depth of digging is 15cm. After emergence, use plastic film to cover cultivation; purple sweet potatoes are generally planted once a year. When the temperature is above 15 degrees, the sooner the cuttings, the better. Generally, spring potatoes should be cut from late April to May, and potato seedlings should be cut horizontally and obliquely. For the best, the distance between plants is 30 cm, and it is advisable to plant three nodes deep. The suitable planting density of purple sweet potatoes per m...

Embodiment 2

[0036] (1) Seed selection: The selection of purple sweet potatoes requires the characteristics of this variety, no pests and diseases, no rot, good quality, and the size of the potato pieces is 250g;

[0037] (2) Cultivate potato seedlings: The method of cultivating purple potato seedlings should adopt three layers of greenhouse + small arched shed + plastic film to increase the number of seedlings to increase the number of seedlings. The width of the seedbed is 9m, and the depth of digging is 18cm. After emergence, use plastic film to cover cultivation; purple sweet potatoes are generally planted once a year. When the temperature is above 15 degrees, the sooner the cuttings, the better. Generally, spring potatoes should be cut from late April to May, and potato seedlings should be cut horizontally and obliquely. For the best, the distance between plants is 33 cm, and it is advisable to plant three nodes deep. The suitable planting density of purple sweet potatoes per mu is 330...

Embodiment 3

[0048] (1) Seed selection: The selection of purple sweet potatoes requires the characteristics of this variety, no pests, no rot, good quality, and the size of the potato pieces is 200g;

[0049] (2) Cultivate potato seedlings: The method of cultivating purple potato seedlings should adopt three layers of greenhouse + small arched shed + plastic film to increase the number of seedlings to increase the number of seedlings. The width of the seedbed is 11m, and the depth of digging is 20cm. After emergence, use plastic film to cover cultivation; purple sweet potatoes are generally planted once a year. When the temperature is above 15 degrees, the sooner the cuttings, the better. Generally, spring potatoes should be cut from late April to May, and potato seedlings should be cut horizontally and obliquely. For the best, the distance between the plants is 35 cm, and it is advisable to plant three nodes deep. The suitable planting density of purple sweet potatoes per mu is 3500 plants...

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a planting method for cultivating high-yield purple sweet potatoes. Background technique [0002] Type the Background Technical Description paragraph here. Purple potato (scientific name: Solanum tuberdsm) is also called black potato, and the potato meat is purple to dark purple. In addition to the nutrients of ordinary sweet potatoes, it is also rich in selenium and anthocyanins. Anthocyanin is the most direct, effective and safe free radical scavenger discovered by the scientific community to prevent and treat diseases and maintain human health. It has preventive and therapeutic effects on more than 100 diseases, and its ability to scavenge free radicals is 20 times that of VC. times, 50 times of VE. Purple sweet potato will become one of the main raw materials of anthocyanins. [0003] The existing planting techniques are: 1. Seed selection; 2. Seedling raising; 3. Soil p...
