| 摘 要： | 为了获得超级稻在沿海地区咸酸田种植的最佳施肥量及最优施肥配比，应用“3414”肥料设计方案进行超级稻田间肥效试验，研究不同配方肥料对超级稻产量及效益的影响。结果表明：超量施肥超级稻增产效果不明显，说明在防城港市较高产成酸田栽培超级稻无法通过超量施肥来取得超高产量；超级稻氮磷钾肥增产效果：氮／16〉磷肥〉钾肥。施肥建议：纯氮240kg／hm2，五氧化二磷904120kg／hm2，氧化钾210～270kg／hm2，最佳施肥配比为1：0．3840．5：0．88～1．1。 |

| Abstract: | In order to obtain the best fertilization amount and combination of super rice in coastal areas, a field experiment of using ＂3414＂ program was conducted to study different combinations＇ impact on yield and benefit of super rice. The experimental results show that excessive fertilization do not lead to higher yield, which means in acid sulfate paddy soil of Fangchenggang City, the super rice yield can not be higher by use more fertilizer. In super rice, the N fertilizer effect is better than P and K fertilizer. The recommended application amount will be pure N 240kg/hm2, phosphorus pentoxide 90--120kg/hm2, potassium oxide 210--270kg/hm2,and the best combination will be 1：0.38--0.5： 0.88--1.1. |
