| 摘 要： | 肥料报酬递减律是施肥学上的经典理论,但其并非植根于肥料研究,而是移植于经济学。研究分析表明,肥料是经济学投入中重要的可变要素,施肥量和作物产量具有一一对应的函数关系,投资和劳动必须借助于影响产量增减变化的可变因素才能起作用。但由于时代的局限性,经济学未能深入研究施肥量与产量的函数关系,因此,经济学报酬递减律缺乏专业研究结果的支持。已有的研究结果证明,肥料报酬递减律是施肥理论和施肥试验方法不完善与计算失误下得出的结论,并非科学规律。

| Abstract: | Though the diminishing rate of fertilizer return is a classic theory in fertilizer science,it does not root in fertilizer research,but economics.Research analysis demonstrates that fertilizer is an important variable element in economic input,and the amount of fertilizer applied has correspondence relationship with crop input.Only affected by variable element of change in output increase/decrease,could investment/labor play role.Unfortunately,limited by the age,economics fails to study the function relation... |
