摘　　要：以农业生态系统思想为指导,采用以组合设计为理论基础的旋转设计,建立了松嫩平原黑土区土壤有效磷以农肥、化肥和秸秆为实验因子的数学模型。采用模型解析的方法,借助于计算机分析、图示等先进手段,研究了农肥、化肥和秸秆与有效磷累积的关系,全面分析了试验因子与有效磷累积关系的规律,并定量地给出了有效磷维持在一定水平的调控途径。Based on the theory of agricultural ecosystem and by using the rotation design method which takes the combination design as its theoretical basis, the mathematical model on available P of soils in the black earth zone of the Songnen Plain as a function of applied farmyard manure, fertilizer and straw were used to study the relationship between the available P accumulation in soils and the application of farmyard manure, fertilizer and straw, And it is analyzed in an all-round way the dynamics of the accumulation of available P in relation to these factors, particularly to single factor and to double factors, and then the way to regulate and control the available P in soils at certain level is given.

关 键 词：农肥 化肥 秸秆 有效磷 数学模型
