摘　　要：６种不同类型土壤中，硝酸盐积累变化为一对数方程，其动态数学模型式Ｎｔ＝ａ＋ｂｌｎｔ。不同类型土壤有机质对硝酸盐积累起主要作用，关系式为ＮＣ＝１４４．２８＋８．８１４＋０．９２４８Ｃ２。在三因素五水平二次通用旋转组合试验中，建立了在施Ｎ量、有机质和ｐＨ条件下土壤中硝酸盐积累的数学模型。The accumulation pattern of nitrate of 6 different soils was aecoded with logarithmic function,the dynamic mathematical equation was Nt=a+bInt. Organism of Soil was principle factor for nitrate accumulation,the equation was Nc=144.28+8.814+0.9248C2.The mathematical model of nitrate accumulation with 3 factors and 5 levels was established.
