摘要
Abstract
[Objective]To study the effects of different fertilization methods on the growth and yield of purple sweet potato.[Method]Field experiments were conducted to study the effects of humic acid,active fertilizer,sweet potato special fertilizer and nitrogen,phosphorus and potassium compound fertilizer on the production,yield and quality of purple sweet potato.[Result]Compared with no fertilizer treatment,three fertilization can increase the number of branches,main stem length and stem diameter,promote the growth of the upper purple sweet potato,potato tuber yield increased 54.8%-67.7%,the yield increased 67.3%-78.6%,humic acid fertilizer and special fertilizer of sweet potato can significantly improve edible quality and anthocyanin content in purple sweet potato.[Conclusion]For fresh varieties and varieties of anthocyanins suggested using humic acid active fertilizer and special fertilizer for sweet potato.关键词
