摘 要: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 work out standardized cultivating measures for Curcuma longa according to the analysis of fresh rhizome simulation model.Method:Second order orthogonal rotative regression design.Result:The fresh rhizome simulation model was built up,and 5 main measures that affect fresh rhizome yield were analyzed by the mathematical model of five unknowns second order orthogonal rotative regression.Sowing time,plant population and potassium play an important role in raising the fresh rhizome yield.Sowing time is clearly interrelated with plant population,and plant population is clearly interrelated with the fertilizer used Sufficient N and K are necessary for raising the yield.There is a clear interrelation among the fertilizer factors.Conclusion:Optimal farming measures:sowing time March 1 17,and plant population 110,000 to 115,000 mother rhizomes per hm 2.The optimal fertilizer requirements have also been formulated.
