Embodiment 1

[0019] A high-yield planting method of red-core sweet potatoes, the planting method mainly includes selecting land, making planting borders, selecting potato seedlings, transplanting potato seedlings, field management and harvesting, specifically comprising the following steps:

[0020] (1) Site selection: choose a flat land with sufficient sunlight, fertile soil, good drainage and loose soil as the planting site, carry out deep plowing in autumn and winter, and weather naturally during the winter;

[0021] (2) Make planting furrows: level the planting land after natural weathering, add 1500-1800 kg of decomposed farmyard manure, 30-35 kg of potassium sulfate fertilizer, 15-20 kg of phosphate fertilizer and 13-15 kg of urea per mu of land as basal fertilizer, and then plow the land to mix the basal manure and soil, and spread a layer of vermicompost with a thickness of 2 to 3 cm on the soil surface, and then cover with a layer of soil with a thickness of 0.5 to 1 cm, and finall...

Abstract

The invention relates to a high-yield planting method of red-core sweet potatoes. The planting method mainly comprises the steps of land selection, planting bed making, sweet potato seedling selection, sweet potato seedling transplanting, field management and harvesting. By the adoption of the planting method, the growth environment of the sweet potatoes can be improved by making planting beds; the manner that vines soaked with a nutrient solution are planted into the planting beds in a cuttage manner, leaf bud section roots of the vines enter the planting beds, and leaf bud section tops are exposed out of the planting beds is adopted, film mulching temperature control cultivation is conducted firstly, and then growing is carried out in the natural environment, so that sweet potato seedlings are easy to take root, the survival rate of the sweet potato seedlings is increased, growth of the sweet potato seedlings is accelerated, the tuberization rate of the sweet potato seedlings is increased, the sweet potato seedlings are guaranteed to fully absorb nutrients from the planting beds, and the quality and yield of the sweet potatoes are greatly improved; and the planted sweet potatoeshave the advantages of being good in condition, safe, free of pollution, less in pest and disease damage and the like, the yield of the method is higher than that of conventional planting methods, andthe method is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of agricultural production and planting, and in particular relates to a high-yield planting method of red-core sweet potatoes. Background technique [0002] Sweet potato is also known as sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, thread sweet potato, white potato, golden potato, sweet potato, red potato, pillow potato, etc. People in different regions call it differently. Sweet potato is the root tuber of the annual plant of Convolvulaceae. Its shape has various shapes such as spindle, cylinder, ellipse and sphere; and its skin color is white, light yellow, red, yellow and purple red. In addition to being used for food, it can also be used to make sugar, wine and alcohol. The calorie content of sweet potatoes is very low, which is much lower than that of ordinary rice, so you don't have to worry about getting fat when eating sweet potatoes. On the contrary, eating sw...
