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 potato per mu is 3000, and there are more potatoes between nodes;
[0026] (3) Site selection: black, purple, sandy, yellow soil is required, the terrain is slightly higher, and it is better to have sufficient sunlight;
[0027] (4) Apply sufficient base fertilizer: Apply sufficient base fertilizer before soil preparation, and balance nitrogen, phosphorus, and potassium fertilization. Generally, 667m2 is applied with 4,000 kg of high-quality soil and miscellaneous fertilizer, 15 pallets of decomposed chicken manure per mu, 20 kg of compound fertilizer, 35 kg of nitrogen, phosphorus, potassium, compound fertilizer, 10 kg of urea, 40 kg of superphosphate, and potassium sulfate 10 kg or 100 kg of plant ash. All organic fertilizers are spread before ploughing, and special organic compound fertilizers can be used as base fertilizers. The compound fertilizers can be used as core fertilizers when ridges are formed, and then deep ploughing is 25 cm deep to thicken the living soil layer;
[0028] (5) Plowing and ridging: Spring potatoes are required to turn 25 cm deep 15 days in advance. Deep furrows and large ridges are better to meet the requirements of deep ploughing and fine soil. The ridge spacing is generally 60 cm and the ridge height is 25 cm;
[0029] (6) Seed potato seedlings: Choose melon buds with flat top three leaves, short internodes, no disease, no aerial roots, seedling age 29 days, and 100 plants weighing 0.4 kg; the planting method requires horizontal planting or 4 nodes. Planted in the soil obliquely, two leaves are exposed to the ground during drought, and the rest of the leaves are buried in the soil to facilitate the survival of the potato seedlings and the uniform distribution of the potato, and increase the commodity rate and yield. Use small ridges for single-row cultivation with a ridge spacing of 70cm, and use large ridges for double-row cultivation with a ridge spacing of 120cm. Make 2 small ridges on the large ridge with a plant spacing of 18cm and a planting density of 4000 plants/667 square meters;
[0030] (7) Reasonable dense planting: Determine the reasonable cutting density according to different soil fertility and characteristics, the spacing is generally 18 cm, 3900 purple sweet potato seedlings per mu in fertile fields, 4400 in thin soil fields;
[0031] (8) Seedling control and topping: When the potato vine grows to 80 cm, the top buds of the main vine should be knocked out in time to promote the side vine, so that the nutrient will be sent to the potato, and the weeds should be removed at the same time;
[0032] (9) Teng: Turning the purple sweet potato disrupts the nutrient delivery, and generally reduces the yield by 30%. It can only pick up the strain, grab loose, and tear off the root hair. Don't disturb the direction when you are titen, but still put it back. Due to the vigorous growth of purple sweet potato vine vines and more adventitious roots between nodes, titen is the key to increase the yield of purple sweet potato;
[0033] (10) Apply sufficient base fertilizer: Apply sufficient base fertilizer before soil preparation, and balance nitrogen, phosphorus and potassium fertilization. Generally, 667m2 is applied with 4,000 kg of high-quality soil and miscellaneous fertilizer, 15 pallets of decomposed chicken manure per mu, 20 kg of compound fertilizer, 35 kg of nitrogen, phosphorus, potassium, compound fertilizer, 10 kg of urea, 40 kg of superphosphate, and potassium sulfate 10 kg or 100 kg of plant ash. All organic fertilizers are spread before ploughing, and special organic compound fertilizers can be used as base fertilizers. The compound fertilizers can be used as core fertilizers when ridges are formed, and then deep ploughing is 25 cm deep to thicken the living soil layer;
[0034] (11) Pesticides: use herbicides and insecticides based on "growing status", that is, purple sweet potato ground pest control. The main types of insect pests include the Ordinary mosquito and the small purple potato weevil. The damage time is from July to September. For 1 to 2 years of age, spraying 5% Nitrophos or 5% Kazeke 1000 times solution on the leaves can effectively reduce the damage.
