摘　　要：以鄂薯7号为材料,通过设置栽插日期与地膜覆盖两个因素研究其对鲜薯产量及干率的影响。结果表明,鄂薯7号地膜覆盖栽培比露地栽培显著增产,干率也有相应的提高。栽插期越早鲜薯产量越高,干率越高。The sweetpotato cultivation technique with less cost and high benefit was explored.Using no mulching as CK,the effects of plastic film mulching and planting periods on dry matter contents,yield were studied in Eshu No.7.The results showed that plastic film mulching could significantly increase the dry matter contents,yield and dry matter contents increased more with planting periods put ahead more.
