| 摘 要： | 为获得水稻栽培中氮、磷、钾最佳施用量,在海南省定安县定城镇后山洋选取有代表性的稻田进行3因素4水平14个处理的肥料效应试验。结果表明,该田块最佳施肥量为纯氮172.35 kg/hm2,五氧化二磷37.5～75.0 kg/hm2,氧化钾115.8 kg/hm2。在中量施肥水平下,肥料对产量的贡献为28.57%;N肥对产量的贡献达到27.20%;P肥为12.01%;K肥为8.66%。

| Abstract: | ＂3414＂ best regression design was used to study the effects of different ration of nitrogen,phosphate and potash fertilizers on yield of rice.Through the equation of ＂3414＂ fertilizer effect experiment,the results showed that,the optimum nitrogen,phosphate and potash dosages of rice respectively were 172.35 kg/hm2,37.5～75.0 kg/hm2,115.8 kg/hm2.Under this experimental condition,the contributive ratio of the middle fertilization on yield was 28.57%;the contributive ratio of nitrogen,phosphate and potash fertilizers on yield of rice reached 27.20%,12.01%,and 8.66% respectively. |
