Abstract

The invention relates to a method for culturing sweet potatoes in a dry land, belonging to the technical field of methods for culturing the crops, and solving the technical problems that the existing method for culturing sweet potatoes in the dry land is unreasonable and has low yield. The technical scheme of the invention is as follows: 1) culturing seedlings: mixing animal wastes with crushed crop straws uniformly according to proportion to prepare padding materials in late March, laying the padding materials on a seedling-culturing bed, then laying river sand, placing sweet potato seeds, then using the river sand to cover the sweet potato seeds, and controlling proper temperature till the seedlings of the seeds grow out; 2) preparing the land and applying fertilizer: after the rains in late March, applying decaying farmyard manure, then ploughing and levelling the land, marking rows and applying potash fertilizer, then leveling again, and covering with thin films; and 3) culturing: from late April to early May, perforating on the thin films and culturing. The method has the advantages of high rate of emergence, capability of maintaining soil moisture, low labor intensity for sweet potato farmers, high yield and the like.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and in particular relates to a dryland sweet potato cultivation method. Background technique [0002] Sweet potatoes are rich in starch, dietary fiber, carotene, vitamins A, B, C, E, potassium, iron, copper, selenium, calcium and more than 10 kinds of trace elements and linoleic acid, etc., with high nutritional value and are nutritious. Scientists call it the most nutritionally balanced health food. These substances can maintain the elasticity of blood vessels, and have the effects of weight loss, bodybuilding, prevention of sub-health, and laxative detoxification. "Compendium of Materia Medica" records that sweet potatoes have the effects of "tonifying deficiency and exhaustion, benefiting energy, strengthening spleen and stomach, and strengthening kidney yin", making people "longevity and less disease". [0003] At present, my country's sweet potato planting area remains at ...
