1984～1993年，以玉米、水稻为供试作物，设置经典的5处理肥料田间试验。结果表明，沈阳市两大主栽作物产量对土壤肥力的依存率为52.6％，余者为肥料效应。土壤氮磷钾养分的保证程度分别为63.6％，83.6％和85.5％。通过基础产量与施肥最高产量回归统计，获得以y＝100x/(a+bx)为模型的两个"以地定产"算式；用基础产量与土壤有效养分含量回归统计，获得土壤有效养分校正系数，就此可算出土壤某种养分供应量，为推行配方施肥技术提供了准确的参数。

The typical fertilizers′expertments were carried on the maize and rice from 1984 to 1993. The results showed that the dependent rate of the two main crop on soil fertility was 52.6%, the other was the effectiveness of fertilizers. The supplying capacities of N, P and K were 63.56%, 83.6% and 85.5%. Meanwhile, the model y＝ 100x/(a+bx) was established (y,the max yield in fertilizing treatment; x, the yield in CK). And the correct coeffcients of avaiable nutrients were obtained.
