| 摘 要： | 根据227个粮油作物氮磷钾肥效试验结果,分别建立土壤肥力为"高"、"中"、"低"3个等级的区域施肥模型.典型性判别表明,35个区域施肥模型中,典型肥效模型占65.7%.对典型肥效模型采用边际产量导数法推荐施肥,对非典型肥效模型则采用Monte Carlo法随机解在目标产量下求推荐施肥量,全省早晚稻平均最高施氮量为162 kg·hm-2,氮磷钾比为1∶0.36∶0.72;经济施氮量是122 kg·hm-2,比例为1∶0.32∶0.65.中稻平均推荐施氮量为206 kg·hm-2,三要素比为1∶0.38∶0.80.甘薯、马铃薯和花生的平均经济施氮量分别为134 kg·hm-2、217 kg·hm-2和107 kg·hm-2,氮磷钾比例分别为1∶0.47∶1.40、1∶0.37∶1.00和1∶0.50∶0.98. |

| Abstract: | Three regional fertilization models for the "high","medium" and "low" soil fertility grades were established based on 227 field tests on the NPK fertilizer efficiency for the grain and oil crops.Representative model analysis showed that 65.7% of the 35 regional fertilization models were typical.The boundary yield derivative method was used to recommend optimum application rate for the typical models.The Monte Carlo method was applied for non-typical models.The results showed that the average maximum N appli... |
