Cultivation method for efficient production of two seasons of sweet potato in year in Huang-Huai-Hai region

Abstract

A cultivation method for efficient production of two seasons of sweet potato in a year in the Huang-Huai-Hai region includes following steps: selecting a fresh-eating sweet potato variety which is disease-resistant, stress-resistant, suitable for mechanical production and early mature, discharging seeds for seedling culture, and paving an electric heating wire of 15-20cm below a seedling culture land seedling bed soil layer during seed discharging; selecting a sandy parcel, adjusting potato seedling planting time and density and fertilizing type and consumption, and shortening growing period of the sweet potato. Variety, seed discharging, planting soil selection, fertilizing and planting are adjusted, planting period of the sweet potato is shortened, the sweet potato cultivated by the method is bright in skin color, good in cooked taste and high in commercial performance, profit space of the sweet potato is expanded, and the problem that growers have high yield without high income is solved; by the method, the two seasons of the sweet potato can be planted in a year, multiple cropping index and unit area productivity of land are improved, economic benefit of farmers in sweet potatoplanting is increased, and coordination and unification of high yield, high quality and efficient production of the fresh-eating sweet potato are realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a method for cultivating sweet potatoes, in particular to a method for efficiently producing sweet potatoes with two seasons a year 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 present, in the Huang-Huai-Hai area, the ...

Problems solved by technology

[0003] At present, in the Huang-Huai-Hai area, the traditional wheat-potato planting mode is the main planting method for fresh sweet potatoes. The continuous cultivation of the land prevents the land from falling fallow and reduces soil fertility. In order to pursue sweet potato production, the growers overuse chemical fertilizers and The spraying of pesticides has caused soil acidification and pollution problems to continue to aggravate, which cannot meet the requirements of high-quality, high-yield, fresh-eating sweet potatoes. In addition, some growers choose to fallow in winter and plant only one season in order to obtain high yields of sweet potatoes and thus obtain better economic benefits. Spring potatoes, although this planting method can obtain high-yield sweet potatoes, but because the potato pieces are too large, the quality is relatively poor, and the commodity is low, the proportion of potato pieces that meet the requirements of buyers is not high, resulting in low prices and profit margins. Households have a good harvest but not a good harvest
