摘 要 ：根据当地肥源和郁金栽培特点，运用二次回归旋转组合设计，进行田间试验，建立郁金有机肥、无机肥配合施用数学模型。有机肥和无机肥对产量的影响大小为：人畜粪、油饼＞过磷酸钙＞氯化钾。通过对模型分析、优化并结合净产值数学模型，筛选出优化方案为：人畜粪４７０００～５３０００ｋｇ／１０４ｍ^２，油饼８４００～９６００ｋｇ／１０４ｍ^２，过磷酸钙１１００～１４００ｋｇ／１０４ｍ^２，氯化钾１５７～２３２ｋｇ／１０４ｍ^２。

Abstract:Regression method of orthogonal conic substitution with factors was employed to build up the tuber models for yield,quality and benefit。 Three main measures affecting the tuber yield,quality and benefit were analyzed by these mathematical models.The effect of agronomic measures on the tuber yield is human and livestock excreta,rape cake>Ca₃(PO₄) ₂>KCl.The optimal combination of farming practices has been obtained according to the analysis of these models.
