Abstract

The invention discloses a cultivation method for improving the taste quality and commerciality of fresh-eating purple sweet potatoes. First, virus-free purple sweet potatoes are selected as seed potatoes, and seedlings are raised in three-dimensional rows, so as to avoid the adverse effects of continuous cropping on seedbeds in saline-alkali soil and the invasion of various disease sources. Improve the quality of potato seedlings; choose sandy loam or loamy soil as the planting plot, adjust the planting time and density of potato seedlings, the type and amount of fertilization, and the control of diseases and insect pests, and appropriately shorten the growth period of purple sweet potatoes, thereby improving the taste and quality of purple sweet potatoes. Commodity. The invention adjusts the aspects of variety selection, seed arrangement, planting soil selection, fertilizer and water, pest control and growth period control, greatly improves the taste quality and appearance quality of purple sweet potatoes, and makes the cultivated purple sweet potatoes thin and smooth. The appearance is correct, the taste of cooked food is good, the meat is dense, and the smell is fragrant, which improves the commerciality of purple sweet potatoes. Commercial potatoes account for more than 90%, which can increase farmers' income and has important economic benefits.
