基于正交试验的高淀粉甘薯新品种川薯217优化栽培技术研究

采用五元二次正交旋转回归组合设计方法,研究栽插密度、栽插期、氮素水平、磷素水平和钾素水平对川中丘陵区高淀粉甘薯新品种川薯217鲜薯产量的影响。结果表明:5种栽培因素对川薯217鲜薯产量的影响顺序为氮素水平〉钾素水平〉磷素水平〉密度〉栽插期,在较大栽插密度,适宜栽插期,充足氮肥的前提下,增施磷钾肥可获得高产。川薯217的高产综合配套栽培措施:密度57750-60255株g/hm^2,6月3日-6月5日栽插,施纯N56.44-61.56kg/hm^2,P20536.8—43.2kg/hm^2,K2053.79—66.21kg/hm^2,可获得37500kg/hm^2以上的鲜薯产量。...

In this experiment, the effects of transplanting density, transplanting period, nitrogen, phosphorus and potassium on the fresh potato yield of high starch sweet potato variety Chuanshu 217 in the hilly region of middle Siehuan were studied with orthogonal experiment by a quadrotic, orthogonal and pivoting regression for five factors. The result showed that the influence of five factors on the fresh potato yield of ' Chu
