| 摘 要： | 研究了钙质紫泥田水稻氮磷钾的施肥效应，分析了肥料的因素效应及合理施用量．结果表明：（1）在试验施肥量范围内，水稻产量与肥料用量呈二次多项式函数关系；（2）磷和氮的效应高、钾肥效应低；（3）棕紫泥夹砂田水稻合理施肥量为每hm^2 N 125-130kg，P2O5 70kg，K2O 0-30kg，下湿紫泥田为N 85-90kg，P2O5 55kg，K2O 0-20kg；（4）地下水位高、湿害严重，是下湿紫泥田生产水平低、施肥效果差的根本原因，改造途径是深沟排水、脱潜治理．

| Abstract: | The effects of nitrogen,phosphate and potash fertilizers and the reasonable amount of fertilizer application on rice in calcareous purple paddy field were studied in this paper.The results showed:(1)the relation of the rice yield and the amount of ferilization was a quadratic polynomial;(2)the yield-increasing effect of nitrogen and phosphate fertilizer was greater than that of potash fertilizer;(3)the proposed reasonable amounts of fertilizer application were 125-130kg N,70 kg P2O5 and 0-30 kg K2O per hect... |
