摘要:
采用3因素二次回归通用旋转组合设计，研究了灌水量、钾肥、磷肥的耦合效应对茄子的影响，得到茄子产量对3因素的回归数学模型。结果表明：1在本试验条件下，3因素影响茄子产量的顺序为施钾量>灌水量>施磷量。2各因素间存在交互作用，水与钾、水与磷、钾与磷在低于1.132和2.312，0.714和0.431，-4.289和4.092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76459.34 kg/hm2 时，相对应的灌水量、施钾量、施磷量分别为2904.6 m3/hm2 、78.6 kg/hm2 、15.5 kg/hm2 。对试验结果进行的验证表明，构建的模型准确可靠。
Abstract:
By means of quadratic general rotational combination design, the comprehensive effects of H2O,N,K2O fertilizer on eggplant was studied, three water-fertilizer coupling regression models demonstrating the relationships between yield and factors were established. Analysis results showed:①The effect of three factors on the yield of eggplant increased by degree in the series of K2O>H2O>P2O5.②The interaction among these three factors existed.There is positive interaction among them in the level lower than 1.132 and 2.312, 0.714 and 0.431,-4.289 and 4.092;and negative interaction among them higher than the levels. By simulation with computer, the amount of N,H2O and K2O for the highest yield were 2 904.6 m3/hm2,78.6 kg/hm2,15.5 kg/hm2 respectively. The experiment proved that the model is accurate and reliable.
