Abstract：To investigate the effect of long-term vegetable production on soil calcium nutrition status,a survey and analysis was conducted on 15 plots of long-term vegetable production distributed in different regions of Fujian.The research results showed that the exchangeable calcium content was 256-923 mg/kg(with an average of 608 mg/kg)and 20.00％belonged to low levels,and 80.00％of soil calcium nutrition belonged to medium levels,without high levels.There was a highly significant negative correlation between soil exchangeable calcium content and pH.There was a highly significant positive correlation between soil exchangeable calcium content and organic matter.There was a negative correlation between soil exchangeable calcium content and available potassium,available phosphorus,and available nitrogen.The soil pH and organic matter were the main factors affecting the effectiveness of soil calcium nutrition.
