摘要
通过二次正交旋转回归设计,探讨了氮、磷、钾及有机肥对胡萝卜中胡萝卜素的综合影响。结果表明:影响胡萝卜素含量的一级(2因素)和三级(4因素)交互作用显著,二级(3因素)交互作用不显著;氮磷、氮钾、磷钾、钾与有机肥、磷与有机肥互作有利于胡萝卜素的积累,氮、磷、钾和有机肥合理配施(1∶0.84∶2.15∶725)可明显促进胡萝卜素的积累;在该试验条件下,有利于胡萝素积累的最佳施肥方案为:N(8.56～9.03kg/667m2)、P2O5(6.99～7.2kg/667m2)、K2O(18.37～19.41kg/667m2)、有机肥(6 159～6 596kg/667m2)。
Field experiment with the design of quadric circurrrregression were performed to investigate the effects of N,P, K and organic fertilizers on carotene content in carrots. The results indicated that the first order interactions and the third order interaction were all significant. Between N and P, N and K, P and K, P and organic fertilizers, K and organic fertilizers was synergistic at the same time that combined application of N, P, K and organic fertilizer could increase significant carotene content in carrots. In this experiment conditions the optimization scheme of fertilizer used for the accumulation of carotene were：N（8. 56-9.03 kg/667m^2） ,P2 05 （6. 99-7. 2 kg/667m^2） ,K2 O（18. 37-19. 41 kg/667m^2）, organic fertilizers（6 159-6 596 kg/667m^2）.
