摘　　要：引进了高淀粉甘薯[Dioscorea esculenta(Lour.)Burkill]品种商薯19,应用正交试验探讨了不同的底肥水平、种植密度以及追肥用量条件下甘薯的综合性状。结果表明,在武陵山气候条件下,商薯19在底肥(复合肥)600 kg/hm^2、密度为7.50万株/hm^2、追肥(尿素)225 kg/hm^2的最佳栽培模式下鲜薯产量达到61 950 kg/hm^2,且大中薯率达到90.3%。In this experim ent,the sweet potato[Dioscorea escuienta(Lour.)Burkill]variety Shangshu19with high starch was introduced.Based on the system principle and method of orthogonal experim ent,the comprehensive traits of sweet potato under different basal fertilizer levels,planting density and nitrogen fertilizer application were discussed.The results showed that,under the climatic conditions of Wuling Mountain,the yield of fresh potato reached61950kg/hm2and the commercial potato could reach90.3%in the best cultivation mode that was density of0.75m illion/hm2,base fertilizer(compound fertilizer)of600kg/hm2and topdressing(urea)of225kg/hm2.
