采用二因素五水平D—饱和优化设计,以两种水稻土进行水稻盆栽试验,对磷、锌肥料用量与水稻产量之间的关系进行研究,建立了水稻产量函数模型。结果表明,磷、锌肥料均能显著地影响水稻产量,其作用大小为锌肥>磷肥。当盘锦盐渍型水稻土施用P2O5 和ZnSO4 为0. 3000、0. 0031gkg-1土、抚顺潜育型水稻土施用P2O5 和ZnSO4 为0. 1317、0. 0108gkg-1土时,获得最高产量。 A two-factor and five-level D-saturation optimization design was adopted to study the relationship between the amount of phosphorus and zinc fertilizer and the rice yield in two paddy soils. A rice yield function model was established. The results showed that both phosphorus and zinc fertilizers could significantly affect the yield of rice, and its effect size was zinc fertilizer> phosphate fertilizer. When P2O5 and ZnSO4 were applied to Panjin salty paddy soil, the highest yield was obtained when P2O5 and ZnSO4 were 0.133,0.0,0108gkg-1 soil, respectively.
