Example Embodiment

[0023] Example one

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

[0025] (2) Cultivation of potato seedlings: The method of cultivating purple potato seedlings should adopt three layers of greenhouse + small arch shed + mulching film to increase the number of seedlings. The seedbed is 10m wide and 15cm deep, and the bottom of the bed is covered with 1 layer of organic fertilizer and then watered and covered with soil. After emergence, it is cultivated with plastic film mulching; purple sweet potatoes are generally planted once a year, and when the temperature is above 15 degrees, the earlier the cutting, the better. Generally, the spring potatoes are cut from late April to May, and the potato seedlings are cut horizontally. For better, the plant spacing is 30 cm, and the depth of planting is three nodes. The suitable planting density of purple sweet potat...

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...
