| 摘 要： | 运用310饱和最优设计,研究了氮磷钾肥配施对球茎茴香产量、维生素C含量的影响,并建立了以氮、磷、钾肥施用量为变量因子,分别以球茎茴香产量、维生素C含量为目标函数的多项式回归模型.判别结果均为非典型性函数,获得球茎茴香产量及维生素C含量的氮磷钾最佳组合范围,666.7m2最高产量施肥组合范围为:Z1(N) =2.821 ～ 10.318 kg,Z2(P2O5) =0.9331～1.4666 kg,Z3(K2O)=1.6005～6.754 kg,最高产量预测值为1242.67 kg;维生素C含量的氮、磷、钾肥料用量最佳组合范围方案为:Z1(N)=1.0395 ～6.4015 kg,Z2(P2O5)=0.9331 ～1.4666 kg,Z3(K2O)=1.6005 ～6.754 kg,最高维生素C含量预测值为85.504mg/kg;优质高产施肥方案是:Z总(N)=2.8465～6.4015 kg,Z总( P2O5)=0.9331～1.4666 kg,Z总(K2O)=1.6005 ～6.754 kg.

| Abstract: | The three factor quadratic D-saturation optimization design(310) was used to investigate the effects of nitrogen,phosphorus and potassium fertilizer on the yield and VC content of spherical fennel,and then their multinomial regressive models were obtained.The results showed that all of the regressive models were non-typical functions.The optimal ranges of nitrogen,phosphorus and potassium for high yield were 2.821~10.318 kg N,0.9331~1.4666 kg P2O5,and 1.6005~6.754 kg K2O per 666.7m2 and the predicted highest yield was 1 242.67 kg per 666.7m2.The optimal ranges of N,P2O5 and K2O for VC content were 1.0395~6.4015 kg N,0.9331~1.4666 kg P2O5 and 1.6005~6.754 kg K2O per 666.7m2,and the predicted highest content of VC was 8.5504 mg per 100 g.In conclusion,the optimal amounts for high yield and good quality were 2.8465~6.4015 kg N,0.9331~1.4666 kg P2O5,and 1.6005~6.754 kg K2O per 666.7m2. |
