摘　　要：田间试验研究结果表明:丘陵红壤旱地种植红薯,稻草全程覆盖条件下栽插均能活棵,有利于红薯成形和膨大,可明显改善红薯的外观品质,能显著增加薯块产量,红薯能够在稻草层中结薯。以稻草覆盖+客土壅薯蔸栽插方式为最佳,每公顷可产鲜薯块30565.5 kg,比CK增产27.85%,薯苗成活率达96.19%。与CK比较,稻草覆盖+有土栽插处理能加快红薯的生育进程。The field experimental results indicated that when sweet potato for fresh food was planted on hilly red soil dry land, covering with rice straw in whole course could make the plants survive, was helpful to the formation and enlargement of tubers, could obviously improve the appearance quality and yield of tubers, and the tubers could form in the rice straw layer. The effect of covering with both rice straw and nutrient soil was the best, in this treatment, the yield of sweet potato was 30565.5 kg/hm^2, being 27.85% higher than that of the check, and the survival rate of sweet potato seedlings reached 96.19%. In comparison with the check, covering with rice straw plus transplanting seedlings into the soil could promote the growth and development of sweet potato.
