不同类型土壤有机质及pH对土壤中硝酸盐积累的影响
Effect of Organism and pH on the Accumulation of Nitrate in Different Soils
【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。
【Abstract】 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.
