摘要
施肥是与产量、品质、成本、土壤培肥、污染等问题密切相关的复合生态系统物质循环调控的重要措施。以实现经济效益、生态效益和社会效益的综合效益最佳为目标 ,建立了“生态平衡施肥”的理论基础和技术体系 ,结合国情提出“生态平衡施肥”实现的关键条件和具体模式。“生态平衡施肥”是以施肥系统养分循环原理“通用施肥模型”为理论基础 ,以实用和高新技术优化组装的技术体系为实现手段 ,以“生态型肥料”为载体的新的施肥系统。“通用施肥模型”建立在质量守恒定律和有效养分转化关系基础上。“生态型肥料”是同时满足高产、低投、没有污染等多目标的最佳肥料投入组合 ,其技术体系包括 :肥料改性、根域或肥域土壤条件改善、减少养分投入、养分再利用和循环技术 ;“生态平衡施肥模型”“特征参数”试验方法、专用肥配方试验方法 ;土壤有效养分速测方法 ;
Fertilization has become a very important strategy that adjusts the nutrient cycle connected with yield,food quality,cost,fertility,non point pollution in the Social\|Economic\|Natural complex Ecosystem(SENCE).We established the theory and technological system of Ecological Balanced Fertilization(EBF)and gave the key factors of EBF in China. EBF is a new fertilization system,which is on the theory of the nitrient cycle(General Fertilization Model,GFM).GFM is established on Mass Conversation Law.Ecological Fertilizer(EF) is a optimal fertilizer compound which simultaneously satisfy multi\|target of fertilization such as higher yield,lower cost,no pollution,etc.Technological system included:1) Techniques of transforming fertilizer characters,improving soil condition,reducing fertilizer dosage,reusing unavailable nutrient,recycling nutrient;2) The experimental methods for determining Diagnostic Parameters(DP) of Ecological Balanced Fertilization Model(EBFM)and fertilizer compound;3)The quickly analysis methods of soil available nutrient;4)Estimating system and management system of fertilization.
