| 摘 要： | 通过晚稻田间"3414"肥效试验,分析比较氮、磷、钾不同施肥水平对浦北县早稻生长和产量的影响,评价土壤有效养分的丰缺,建立三元二次肥料效应方程并计算出最佳经济施肥量。结果表明:在浦北县酸性结晶岩类残积物地区的稻田,氮、磷、钾养分对早稻植株经济性状、产量的影响中,氮占主要,钾次之,磷较小;在全氮含量2.06g/kg、速效磷含量22.4mg/kg、速效钾含量62mg/kg的土壤肥力条件下,每667m2施N:11.33kg,P2O5:3.282kg,K2O:7.444kg时产量最高。

| Abstract: | Through the experiment, an analysis and comparison was conducted for impacts on early rice growth by different fertilization levels of N, P, K in order to evaluate soil effective-nutrients, set up a quadratic formulation for best fertilization amounts. The results show that in the acidic paddy field of the County, N has the most important impacts on economic features and yield, then the K and P. In the condition of total N 2.06g/kg, quick-acting P 22.4mg/kg and quick-acting K 62mg/kg, the application of N ： 11.33kg, P2O5： 3.282kg, K2O ： 7.444kg/667m^2 can have the highest yield. |
