【摘要】 试验采用二次回归正交旋转组合设计,研究了松嫩平原西部风砂土区大豆籽粒产量与氮肥、磷肥、钾肥、锌肥、钼肥五因素的定量关系,建立了产量形成的肥料反应模型,解析了各因素对总产量的主效应及互作效应,寻求定量生产水平下的最佳农艺措施,得出风沙土区大豆高产栽培措施为:N:101 9～113 8kg/hm2、P2O5:112 0～119 8kg/hm2、K2O:108 6～112 9kg/hm2、Zn:73 9～86 1g/hm2、Mo:102 0～114 4g/hm2。更多还原

【Abstract】 The relationship on soybean yield in blown soil in the west part of Songnen plain with nitrogen, phosphorus, potash, zinc and molybdenum fertilizers were studied, and a mathematical model involving the five factors and soybean yield was established by using the orthogonal rotation design. The effects of individual factor and its interactions on yield were determined and the optimum agronomic practices in certain conditions were found by analyzing the model. The optimum comprehensive practices of high yield in blown soil area were, N, 101.9～113.8 kg/hm², P₂O₅, 112.0 ～119.8 kg/hm², K₂O, 108.6 ～112.86 kg/hm², Zn, 73.9 ～86.1 g/hm², Mo, 102.0～114.4 g/hm².更多还原
