Abstract

The invention relates to a high-yield planting method of sweet potatoes in fields. The planting method comprises the steps as follows: uniformly mixing countryside soil, sandy soil and strontium ore powder in proportion to obtain matrix soil; flatly laying 10-15 kg of the matrix soil and 10-20 kg of field mud on land per mu, deep plowing the soil for 8-10 cm, scattering 90-100 kg of plant ash permu, deep plowing the soil for 15-20 cm, covering the soil with mulching films, and performing treatment for 30-50 days; removing the mulching films, uniformly applying 15-20 t of composted farmyard manure per square hectometer, deep plowing the soil for 20 cm, and performing ridging; selecting healthy sweet potato seedlings and obliquely inserting the seedlings on ridge surfaces; covering soil permu with 3-4 mu of wheat or corn straw and uniformly laying the wheat or corn straw on the surface of a sweet potato field; mixing an organic nutrient and clarified limewater and performing spray treatment once; carrying out drip irrigation watering, fertilization, pest control and weeding; harvesting and storing sweet potatoes. By means of the planting method, the nutrient supply demand in the sweet potato planting process can be met, so that the growth quality of the sweet potatoes is guaranteed, and the yield of the sweet potatoes is increased.

Description

technical field [0001] The invention relates to the technical field of high-yield planting of sweet potatoes, in particular to a method for high-yield planting of sweet potatoes in the field. Background technique [0002] Sweet potato is an important root crop for food, feed, industrial raw materials and new energy. It is widely planted in more than 100 countries in the world and ranks seventh in the world's food production. About 70 million mu of sweet potatoes are planted in my country, accounting for 45% of the world's sweet potato planting area, and more than 100 million tons of fresh potatoes are produced, accounting for 75% of the world's total production. [0003] Sweet potato is also called sweet potato, red moss, sweet potato, sweet potato. The nutritional value of sweet potato is very high, and it is a healthy food with both medicine and food; sweet potato is rich in potassium, β-carotene, folic acid, vitamin C and vitamin B6, and these five ingredients are helpfu...
