摘要
利用二次通用旋转组合设计，经微机分析，建立了氮磷钾与保护地番茄产量形成及果实品质的数学模型。结果表明，氮对产量形成及果实的品质影响最大。在适宜范围内，随着施氮量的增加，产量明显增加，果实中的维生素Ｃ、还原糖及有机酸的含量增加。施氮过量则产量变低，品质变劣。磷钾肥对促进番茄产量形成具有间接作用，利于提高番茄产品品质。但过量施用磷钾肥也对果实品质不利。
By means of quadratic rotational combination design,a three-factor (N. P. K) experiment was conducted in a solar greenhouse. With the aid of computer,the mathematical models of the relationship between N. P. K and the effects on the yield and quality fo tomato were established. The results showed that N had a biggest effect on yield and quality of tomato,while the interaction between N. K is the most significant,and that the application rate of N. P. K all influence tomato's quality.
