| 摘 要： | 为了科学准确地施肥,对测土配方施肥法与常规施肥方法进行了对比试验。结果表明:N2P3K2产量最高为10 422.9kg.hm-2,其次是N2P2K2产量为10 366.9kg.hm-2;N2P3K2产投比为14.9∶1,N2P2K2产投比为16.8∶1,因此就其经济效益来说N2P2K2比例较为合理;氮肥最佳施用量为198.7kg.hm-2;磷肥最佳施用量为136.0kg.hm-2;钾肥最佳施用量为152.9kg.hm-2。

| Abstract: | In order to achieve high efficient application of fertilizer,normal method and local method were compared in this experiment.The result showed that the highest yield was 10 422.9 kg·hm-2 with treatment of N2P3K2,the following was 10 366.9 kg·hm-2 with treatment of N2P2K2.The ratio of output to input with application of N2P3K2 was 14.9∶1,while N2P2K2 was 16.8∶1.Therefore,the economic benefit of N2P2K2 was rational;The optimum amount of Nitrogen was 198.7 kg·hm-2,phosphate was 136.0 kg·hm-2 and potassium was 152.9 kg·hm-2. |
