摘　　要：选择扦插密度、尿素用量和硫酸钾用量3个因子，采用单形格子设计，布置田间参数试验，建立了3个供试因子对于鲜薯产量和净产值的回归数学模型。结果表明：在该试验条件下，“心香”的扦插密度为3300～3600株／667m^2，尿素用量约15kg／667m^2，硫酸钾用量13～18kg／667m^2，可以实现增产增收。The cutting density,amount of urea application and amount of potassium sulfate application were selected as three factors and a field experiment of planting＂Xinxiang＂ sweet potato cultivar was carried out according to simple lattice design. Based on the experimental results, regression models of the fresh sweet potato yield and net output value were established with the three factors. According to the regression analysis and production actuality, it was considered that under the given conditions, the cutting density, amount of urea application and anount of potassium sulfate application should be respectively 3 300～3 600 plants/667 m2, 15 kg/667 m2 and 13～18 kg/667 m2.
