重庆市江津柑橘果园土壤pH与盐基饱和度的关系探讨

Relation of pH and Cation Saturation of Orange Orchard Soil in ChongQing Jiangjin

根据江津市柑橘果园土壤71个灰棕紫泥土样的分析资料,应用统计方法,探讨pH和盐基饱和度的关系。土壤pH与盐基饱和度呈y=8.4451x2+115.54x-305.28,R2=0.8541非线性正相关,且受占优势的交换性Ca2+制约。分析了盐基饱和度的可能的影响因素。

According to analyzed data of grey brown purple soil samples of Jiangjin orange orchard, We discussed application, Statistic method, and relation between pH and cation saturation. Relation between pH and saturation showed y =8.4451x^2＋115.54x -305.28 ,R^2-0.8541.
