| 摘 要： | 本文以肥效评价的生态平衡施肥理论体系为基础,对生态平衡施肥指标体系进行了研究。(1)以肥料转化率为基础建立了全量养分通用施肥模型和参数体系:在Wj=Wi状态下,模型为Win=Wyield/Kyield,参数为产量和肥料转化率;在Wj>Wi状态下,模型为Win=Wyield/Kyield,参数为产量和肥料转化率;在WjWi状态下,模型为Wleave=Kleave×Win或Kleave=1-Kyield-Kfertilization,参数为产量、肥料转化率和(Wj-W)i或Kfertilization。(3)以肥料培肥率为基础建立了土壤培肥模型和参数体系:在Wj>Wi时,肥料培肥率模型为Kfertilization=(Wj-W)i/Win,参数为产量和肥料培肥率。(4)以中长期定位试验为例说明了以上模型...

| Abstract: | This paper was based on the theory system of Ecological Balanced Fertilization for fertilizer efficiency evaluation and investigate the index system of Ecological Balanced Fertilization:(1)universal fertilization model and parameter system of total nutrient were established based on Fertilizer Yield:model was Win=Wyield/Kyield when Wj=Wi,parameters were yield and fertilizer yield;model was Win=Wyield/Kyield when Wj>Wi,parameters were yield and fertilizer yield;model wasWin=Wyield/Ks-yield+(Wj-Wi) when Wj
