摘要： 采用三元一次回归正交试验设计对番茄椒（tomato sweet pepper，tsp）进行N、P、K配方施肥,研究其对产量及品质的影响。结果表明：对产量的影响顺序为氮肥>磷肥>钾肥。氮、磷、钾三者之间存在着交互作用。所得的多项式回归方程＝37.71＋8.14 X1＋4.61 X2＋2.06 X3＋1.6 X1X2±13.80与实际值吻合较好。在增施N肥的同时增施P、K肥有利于增加番茄椒的含糖量、Vc含量。每666.7m2施N 20.9kg，P2O5 5.7kg，K2O 25.1 kg（处理1）时，番茄椒还原糖、蔗糖、VC含量最高，分别为4.88%、0.47%和175.39mg/100g；在高N、低P、低K的情况下，番茄椒总糖及VC含量反而降低。在低N的情况下增施P、K肥，番茄椒含糖量和VC含量增加不明显。N、P、K的合理配方施肥有利于提高番茄椒的产量和品质

Abstract: Trinomial one time regression orthogonal design was used to fertilize the tomato sweet pepper with N, P and K according to prescription and study its effect on yield and quality. The results showed that the effect on yield was N>P>K, and they interact each other. The polynomial regression equation, obtained as follow ＝37.71＋8.14 X1＋4.61 X2＋2.06 X3＋1.6 X1X2±13.80, accords with the real values. The sugar, ascorbic acid content will increase when much N was fertilized, as well as P and K. The reducing sugar, sucrose, and Vc content of tomato sweet pepper were highest and reach 4.8%, 0.47%, and 175.39mg/100g when 20.9kg K, 5.7kg P2O5, 25.1 kg K2O (treatment 1) were fertilized in 666.7m2, respectively. The total sugar and Vc will decrease when higher P and K were fertilized at lower N. It was not obvious for the total sugar and Vc enhancement when P and K were increased at low N. The reasonable fertilizing according to prescription of N, P and K will increase the yield and quality of tomato sweet pepper.
