摘    要:目的]研究在水稻高产区氮、磷、钾肥对晚稻产量和经济效益的影响。方法]采用“3414”肥效试验方案研究氮、磷、钾肥不同用量对水稻的影响。结果]高肥力地区施肥效果与其他地区明显不同,合理施用氮磷钾肥可显著增产,经济效益显著,而不合理施肥则经济效益极低甚至亏损。通过拟合一元二次肥效模型,确定晚稻最高施肥量为N249.9kg/hm^2、P2O5 62.2ks/hm^2、K2O 128.7kg/hm^2,最佳经济施肥量为N189.2kg/hm^2、P2O5 55.2kg/hm^2和K2O 101.1kg/hm^2。结论]合理施用氮、磷、钾肥是水稻增产增收的有效措施。

关 键 词:晚稻  "3414"肥效试验  产量  推荐施肥量
