| 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)。

| Abstract: | Field experiment with the design of quadric circum-regression 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 th... |
