目的：通过姜黄农艺措施优化数学模型研究，为制定规范化栽培技术提供依据。方法：二次正交回归旋转组合设计。结果：各项农艺措施对产量的影响大小为播期＞ 密度＞ 氯化钾＞ 复合肥＞ 过磷酸钙。播期与密度之间存在互作效应，密度与复合肥、钾肥和磷肥间存在互作，复合肥与磷肥和钾肥之间也有互作效应。结论：高产优质高效综合农艺措施为，播期３ 月１ ～１７ 日，密度１１ ．０ ～１１ ．５ 万个母姜／ｈｍ ２ ，施肥量：复合肥１４００ ～１７００ｋｇ·ｈｍ － ２ ，过磷酸钙１０００ ～１６００ｋｇ·ｈｍ － ２ ，氯化钾１００ ～１５０ｋｇ·ｈｍ － ２ 。实施该优化组合方案，干旱条件下姜黄根状茎鲜重产量在１２０００ｋｇ·ｈｍ － ２ 以上，总姜黄素≥３ ．０ ％ ，挥发油含量≥７ ．８ ％ ，净产值为５４００ 元／ｋｍ ２ 以上。
Objective: To study the mathematical model optimization of turmeric agronomic practices and provide evidence for the development of standardized cultivation techniques. Method: quadratic orthogonal regression rotation combination design. Results: The effect of each agronomic measure on the yield was sowing time> density> potassium chloride> compound fertilizer> superphosphate. There is an interaction effect between sowing date and density, and there is an interaction between density and compound fertilizer, potash fertilizer and phosphate fertilizer. There is an interaction effect between compound fertilizer and phosphate fertilizer and potassium fertilizer. Conclusion: The comprehensive agronomic measures of high yield, high quality and high efficiency are sowing date from March 1 to 17 and density of 11. 0 ~ 11. 50000 Ginger / hm 2, fertilizer: 1400 ~ 1700kg · hm - 2 of compound fertilizer, 1000 ~ 1600kg · hm - 2 of superphosphate and 100 ~ 150kg · hm - 2 of potassium chloride. Under the optimized conditions, the fresh weight of turmeric rhizome was more than 12000kg · hm - 2 under drought condition, and the total curcumin ≥3. 0%, volatile oil content ≥7. 8%, the net output value is 5400 yuan / km 2 above.
