摘　　要：在施肥和栽培方式相同的条件下,探索脱毒红薯藤蔓移栽大田后不同生育时期摘心、提蔓、翻蔓等7种不同的管理方式对脱毒红薯产量的影响。结果表明,不同管理方式对脱毒红薯产量影响差异显著。其中,以脱毒红薯主藤长到12叶节时摘主心、保留主藤8个叶节,第1次侧枝枝藤长到17叶节摘心、保留侧枝15个叶节的处理产量最高。提蔓与翻蔓2种管理方式比较,提蔓管理较翻蔓管理更为科学合理。说明,在脱毒红薯的栽培管理上适时摘心和适时提蔓是高产的关键技术。Seven different field management patterns including tip pruning, raising bind, turning over bind and so on were tested at different growth stages of sweet potato with virus-free after transplanting under the same application and cultivation conditions to study the effect on its yield. The results showed that there was significant difference in yield between seven different management patterns, the yield of the treatment with tip pruning （retaining main bind with 8-leaf segment and first branch bind with 15-leaf segment） when main bind had 12-leaf segment and the first branch binds was 17-leaf segment,was the highest in all treatments, and the effect of the raising bind management pattern was better than the turning over bind management pattern. Therefore, the key management measures to improve yield of sweet potato with virus-free are tip pruning and raising bind at the right moment.
