Abstract Sweet potato is an important autumn crop， and its yield and quality are not only directly affected by variety and soil conditions， but also by fertilization. In order to study the fertilizer requirements of sweet potato. Reasonable and effective fertilization based on the fertilizer requirements of sweet potatoes， and selecting appropriate fertilization methods according to local conditions， are effective ways to improve the yield and quality of sweet potatoes. This article takes the fertilizer requirements of sweet potatoes as the starting point， analyzes the impact of fertilizer types on the growth of sweet potatoes， summarizes the fertilization techniques for sweet potatoes， and provides reference for the high yield and efficient cultivation of sweet potatoes.
Keywords sweet potato; characteristics of fertilizer demand; fertilization techniques
