生态平衡施肥模型理论与应用

Theory and application of ecological balanced fertilization model

根据质量守恒定律和肥料—土壤—作物间养分转化关系,提出施肥机理模型的一般数学表达式:W=P+Lfsp+(Tn+1-Tn)×2.25(或0.15),称之为“生态平衡施肥模型”.初步应用结果表明,按此模型推荐的施肥量比目标产量法减少17%～22%.

This paper evaluated current fertilization models, and then introduced a theory and an establishment process of a new fertilization model, called ecological balanced model.
