中文摘要	采用3因素2次回归通用旋转组合设计,研究了铁、锰、锌肥配施对茄子生长的影响,得到茄子产量对3因素的回归数学模型。结果表明:3因素影响茄子产量的顺序为施锰量>施铁量>施锌量。各因素间存在交互作用, 铁与锰、铁与锌、锰和锌在低于0.525和1.268、0.525和0.416、1.268和0.416施肥水平时对产量存在正相关关系, 在分别高于以上水平时又会呈负相关关系。经过计算机模拟,得到茄子最高产量达34.62 t/hm~2时,相对应的铁、锰、锌肥用量分别为47.85、35.85、6.15 kg/hm~2。对试验结果进行的验证表明,构建的模型准确可靠。
英文摘要	Factor quadratic regression with 3 general rotation designs was adopted to study the effects of Fe, Mn and Zn fertilizers on the growth of eggplant, and the regression model was obtained among yields and 3 factors. The results showed that the influence of 3 factors on eggplant yield was in order of Mn> Fe> Zn. There were interactions among various factors. Fe and Mn, Fe and Zn, and Mn and Zn had positive correlations to yield below levels of fertilization 0.525 and 1.268, 0.525 and 0.416, 1.268 and 0.416, but had negative correlation when levels of fertilization being higher. The highest yield of eggplant was 34.62 t/hm~2 based on computer simulation, corresponding to the fertilizer amounts of Fe, Mn and Zn were 47.85 kg/hm~2, 35.85 kg/hm~2 and 6.15 kg/hm~2, respectively. The established model was validated accurately and reliably by tests.
