摘　　要：以氮、磷、钾为主要影响因子,采用"311-A"二次回归最优设计进行试验研究,利用肥料效应函数法建立了加工番茄施肥模型,并分析了3种肥料与番茄产量之间的关系。结果表明,氮肥和钾肥对加工番茄产量影响较大,磷肥次之。根据模型确定了经济最佳施肥量和最高产量施肥量,针对不同的情况选择合适的施肥量,为合理施肥提供了科学指导。In this paper,considering nitrogen,phosphorus and potassium as the main influencing factors, using ＂311-A＂ Optimal design of quadratic regression test through the method of fertilizer effect function to establish the processing tomato fertilization model. Analyzing the relationship between the three fertilizer and tomato yield. The results showed that nitrogen and potash have a greater impact on the production of processing tomato, phosphate has the smallest effect. According the model to determine the highest yield of fertilizer and economic optimum fertilization for different situations to choose the right amount of fertilizer,providing scientific guidance for rational fertilization needed.
