摘要：

合理配置针对不同品种的栽培技术可提高作物产量，并降低化肥的过度使用。对淀粉型甘薯新品种“泰中9号”采用五因素（1/2实施）通用旋转回归组合设计试验方法，分析了氮肥、磷肥、钾肥、密度、插秧期对该甘薯品种鲜薯产量的影响，结果表明影响程度依次为：钾肥（X3）﹥磷肥（X2）﹥密度（X4）﹥氮肥（X 1）﹥插秧期（X5）。“泰中9号”甘薯产量在3265.15-4127.96kg/666.7m2的1532个组合中优化栽培方案是：折合纯 N 10.7～11.88kg/666.7m2，纯 P2O5 5.44～6.01kg/666.7m2，纯 K2O 15.15～19.83kg/666.7m2，适宜的栽培密度范围是4048～4525株/666.7m2，适宜的插秧期范围为4月22日至4月29日。本研究可为能源型甘薯“泰中9号”的高产种植提供依据和参考。

Abstract:

Suitable cultivation models designed for certain varieties could increase crop yield and reduce the excessive use of chemical fertilizers. Using the starch-rich sweet potato cultivar ‘Taizhong 9’ as planting material, a field trial with general rotary regression design under 5 factors was conducted to study the effects of nitrogen, phosphate, potassium, planting density and cultivation time on yield of fresh storage roots. Our results indicate that these factors in order of importance are potassium fertilizer (X3), phosphorus fertilizer (X2), planting density (X4), nitrogen fertilizer (X1) and cultivation time (X5). The suitable model for ‘Taizhong 9’ in the 1532 combinations with yield between 3265.15 and 4127.96kg/666.7m2 can be designed as N 10.7-11.88 kg/666.7m2, P2O5 5.44-6.01kg/666.7m2, K2O 15.15-19.83kg/666.7m2，planting density of 4048～4525 plants/666.7m2, and cultivation time from April 22 to 29. This study provides a basis and reference for high-yield cultivation of cultivar ‘Taizhong 9’ in the region.
