| 摘 要： | 通过"3414"最优回归设计方法,研究了氮、磷、钾不同配比对水稻产量的效应。结果表明,不同处理间产量差异达极显著水平,以施用N135 kg/hm2、P 33.75 kg/hm2、K78.75 kg/hm2的产量最高、效益最好。在中量施肥水平下,肥料对产量的贡献为36.2%;氮肥对产量的贡献达到30.8%;磷肥对产量无效;钾肥对产量的贡献为6.4%,效果不明显。

| Abstract: | "3414"best regression design was used to study the effects of different ration of nitrogen,phosphorus and potassium on yield of rice.The results showed that significant difference existed among different treatments.Treatment with N 135 kg/hm2,P 33.75 kg/hm2,K 78.75 kg/hm2 had the highest yield and benefit.Under this experimental condition,the contributive ratio of the middle fertilization on yield was 36.2%;the contributive ratio of N,P,K fertilizer on yield of rice reached 30.8%,0% and 6.4% respectively. |
