摘要: 为了明确山西南部碳酸盐褐土日光节能温室土壤肥力变化特征和指导菜农科学地进行日光节能温室养分资源管理,系统地研究了栽培0~10年日光节能温室土壤的pH、EC值、OM、全N、有效P、硝态N、速效K、交换性Ca和交换性Mg的变化趋势。结果表明,栽培年限与土壤EC值、OM、全N、有效P、硝态N、交换性Mg呈显著正相关,其中OM、全N的相关系数最高,速效K增加相关系数最低;随栽培年限增加,土壤pH和交换性Ca下降,栽培年限与二者的相关系数分别为-0.584和-0.281。对土壤化学特征的相关性分析表明,栽培年限增加引起的土壤养分元素变化不协调。

Abstract: The changes of carbonate soil chemical characteristics,which include pH,EC,Organic matter,TN,Olsen-P,NO3——N,exchangeable Ca and exchangeable Mg,under conditions of solar greenhouse were analyzed in order to offer guideline about nutrient resource management.The results demonstrated that EC,organic matter,TN,Olsen-P,NO3——N,exchangeable Ca and exchangeable Mg were enhanced with the increase of planting years.Among them,the correlations(r)between planting years and organic matter,TN were 0.787 and 0.778,respectively.Soil pH and concentration of exchangeable Mg were decline with planting years.The analysis of correlation between every two items of soil chemical characteristics,it was found that the changes of soil chemical factors were not coordinate.
