摘　　要：甘薯是世界主要粮食作物之一,也是重要的工业原料作物和饲料作物。近年来,中国学者对甘薯高产栽培技术进行了大量研究。为了提高能源型‘商薯19’的产量,采用正交实验方法,通过对甘薯栽培技术中不同移栽时间、种植密度、起垄宽度、起垄高度4个因素进行组合试验,进行甘薯增产对比试验研究,以筛选出最佳综合配套技术措施方案,指导大田生产。结果表明:处理5组合的产量最高,与其他各组存在极显著差异。即适时早插,起垄适当,合理施肥是提高甘薯产量的重要栽培管理措施。The ipomoea batatas lam is one of world staple food crops, also is the important industrial crop and the feed crops. In recent years, the domestic scholars have conducted the massive research to the high yield cultivation technique of the ipomoea batatas lain. In order to improve the yield of ＇Shangshu 19＇, the article uses the orthogonal experiment method through combining the experiment, basing on the cultivation technology of ipomoea batatas lam in different transplanting time, planting density, ridge width, ridge height four factors. The article conducts the contrast experimental study for the ipomoea batatas lam, in order to select the best comprehensive technique measures and guide the field production. The results showed that, the five combinations got the highest yield. There were significant differences with other groups. The important cultivation and management measures were the timely plug, the proper ridge and the rational application of fertilizer.
