Problems solved by technology

[0003] The present invention aims at the existing problems: the planting of sweet potatoes is affected by environmental factors such as soil, temperature, humidity, light, etc., the sugar content in the planted sweet potatoes is low, the content of starch and cellulose is too high, the mouthfeel is seriously powdered when eaten, and the taste is sweet. It is relatively low and cannot be used for the processing of products with high added value such as roasted sweet potatoes and sweet potato chips. Normal crops are planted, resulting in waste of land resources
