Problems solved by technology

The traditional planting of sweet potatoes is planting with single plant in one hole and equal row spacing. This planting method has poor plant permeability, and the root growth of crops, surface water evaporation rate and night temperature distribution are all unfavorable for the growth of sweet potatoes, resulting in the yield of this planting method. Low, poor grain quality and other disadvantages, and it is not conducive to field management and harvest, at the same time, it will also lead to low yield of sweet potato

Abstract

The invention relates to a planting method of a high-yield high-quality sweet potato. The planting method particularly comprises the steps of breeding seedlings, preparing soil and regulating moisturein the soil, carrying out planting, carrying out field weeding, carrying out water and fertilizer management and disease and pest management. With the planting method, 4-7kg of sweet potato tuberousroots can be produced by each plant of sweet potatoes, so that the per mu yield is greatly improved; the pesticide usage amount in a planting process is low, and the usage amount of chemical fertilizers is low, so that the planting method is safe and environmentally friendly; the field working time is short, so that the labor intensity of sweet potato planting households is greatly reduced; the production cost is low; the sweet potato obtained by planted contains no harmful substances to human bodies and is safe to eat; the operation is simple; the cultivation technology is novel; the plantingdensity is scientific and reasonable; and the quality and yield of the sweet potatoes are improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and in particular relates to a method for planting sweet potatoes with high yield and high quality. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato, sweet potato, etc., people in different regions call it differently. People in Shandong call it sweet potato, people in Sichuan call it sweet potato, people in Beijing call it sweet potato, and people in Fujian call it sweet potato.
