Cultivation method for improving water-saving and drought-resistant ability of sweet potatoes in spring in Huang-Huai-Hai area

Abstract

A cultivation method for improving the water-saving and drought-resistant ability of sweet potatoes in spring in the Huang-Huai-Hai area comprises the following steps: selecting a rareripe fresh-eating sweet potato variety with good quality, high commodity property and strong drought resistance and cold resistance; selecting a sandy land block; planting astragalus including seed preprocessing, seed dressing, sowing, field management, crushing and returning; planting sweet potatoes including adjustment of the planting time and the planting density of potato seedlings and the types and the application amount of fertilizers and disease and pest prevention and control, so that the eating quality and the commodity of the sweet potatoes are improved. According to the cultivation method, the adjustment is carried out from the aspects of variety, planting soil selection, soil moisture preservation, fertilization, planting, disease and pest prevention and control and the like, so that the soildryness is greatly reduced, the transplanting survival rate of sweet potato seedlings is remarkably improved, the soil organic matter content is increased, the yield of the sweet potatoes is increased, the appearance commodity of the sweet potatoes is greatly improved, and the size of the cultivated sweet potatoes is moderate and uniform; the cultivated sweet potatoes are bright in skin color, good in taste after cooking and high in commodity property, and the income of farmers is increased; the method has important economic benefits.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a cultivation method of sweet potatoes, in particular to a cultivation method for improving the water-saving and drought-resistant ability of sweet potatoes in spring in the Huanghuaihai region. Background technique [0002] Sweet potatoes are mainly divided into three types: fresh food type, starch type and pigment type according to the quality characteristics and uses of their tubers. According to data, fresh sweet potatoes are rich in various vitamins and minerals, especially carotene and rich and delicate dietary fiber. Therefore, consumers' demand for fresh sweet potatoes has been increasing year after year, and they have begun to pay attention to the quality of their flavor. The planting area of ​​fresh sweet potatoes has expanded year by year, and the planting benefits are generally higher than other types of sweet potatoes. [0003] At presen...

AI Technical Summary

Problems solved by technology

Spring in this area is characterized by drought, little rain, sufficient light, and large evaporation. However, sweet potato seedlings in spring greenhouses are tender and weak, and field transplanting is easily affected by drought and little rain, which seriously affects the growth and yield formation of sweet potatoes.
