为了研究种植密度、氮、磷、钾施用量及配比对‘定薯1号’品种产量、出苗率、单株薯重、商品薯率等的效应，利用二次通用旋转组合设计及计算机模拟寻优的方法，寻找‘定薯1号’适合种植在旱作农业生态区域的高产栽培技术方案。结果表明：产量高于13957 kg/hm2的高产农艺组合方案有61套，各因子的取值范围分别为：密度39235.98～66272.22株/hm2，施N 96.41～236.22 kg/hm2， P2O538.60～94.46 kg/hm2， K2O 173.60～411.63 kg/hm2，N：P2O5：K2O约为2.4：1：4.9。

The Effects of plant density, N, P, and K applications were studied on tuber yield, emergence percentage, tuber weight per plant and marketable tuber percentage using the Quadratic General Rotary Unitized Design and Computer Simulation Optimization methods in order to identify high-yielding agronomic measures for the variety 'Dingshu 1' in arid farming region. Sixty-one technological schemes were found for‘Dingshu 1’when tuber yield was more than 13 957 kg/ha. The factor value range was, respectively, 39 235.98- 66 272.22 plants/ha for plant density, 96.41- 236.22 kg/ha for N, 38.60-94.46 kg/ha for P2O5, and 173. 60-411.63 kg/ha for K2O, in which N:P2O5:K2O was roughly 2.4:1:4.9.
