摘　　要：本文讨论了滦平试区春玉米在不同水分条件下的肥料─产量效应和不同肥力条件下的水分─产量效应。研究结果表明，在中等肥力条件下，水分─产量效应接近显著水平，而肥料─产量效应在任何水分条件下均为正效应。作者认为，在目前生产力水平条件下，限制产量的主导因素是肥而不是水。本文研究结果对于当地春玉米合理种植具有一定价值。The paper discusses the fertilizer-yield effect under different water conditions and water-yield effect under different fertility conditions for spring maize in experimental area of Luanping. Research results indicated that water-yield effect approaches outstanding level under intermediate fertility conditions while fertilizeryield effect appears positive effect under any water conditions. It is held that leading factors limiting yield is fertilizer rather than water under present conditions of productivity. The research results presented in the paper are of certain values to the rational close planting locally.
