| 摘 要： | 测算肥料利用率的同位素标记法受土壤、肥料间交互作用的影响,而通常肥料试验的差值法则既受土壤、肥料间交互作用,又可能受施肥直接抑制作物吸收土壤养分的双重影响,猜想这两种测算方法都不可能获得可靠结果.本文在给出若干假设的基础上,提出了适用于通常肥料试验估算肥料利用率的替代方法.该法可归避上述影响干扰,但其可靠性有待实验证实.

| Abstract: | The measurement of fertilizer recovery either by isotope tracer technique or by field experiment with plots fertilized and unfertilized, both were suspected unreliable and reasons were discussed. Based on some reasonable presumptions, an alternative way of estimating fertilizer recovery by field trials was proposed in this paper, but further examination on it's reliability is needed. |
