| 摘 要： | 对晋南南部300个蔬菜土壤样品的分析研究结果表明:蔬菜土壤钙含量比大田土壤钙含量低1.52g/kg;保护地蔬菜土壤钙含量比露地蔬菜土壤钙含量低1.47g/kg;保护地蔬菜土壤钙含量基本上随着土壤深度的增加而增加,钙含量最高层为50～100cm,而露地蔬菜土壤钙含量在不同土层间的变化没有规律;无论是保护地蔬菜,还是露地蔬菜土壤钙含量均随着种植年限的增加而降低。土壤有机质含量与土壤钙含量呈明显的负相关;土壤PH值与土壤钙含量呈显著的正相关;蔬菜产量与土壤钙含量之间呈显著的负相关。影响土壤钙含量变化的主要原因是随着蔬菜产量的增加,从土壤中携带出的钙量相对较多,含钙肥料使用量减少及土壤有机质的提高和土壤PH值的下降。

| Abstract: | The analysis of 300 vegetable soil samples in the south of jinnan shows that: the calcium content of vegetable soil is lower than the calcium content of field soil by 1.529g/kg;the calcium content of sheltered ground vegetable soil is lower than of open ground by 1.479/kg;the calcium content of sheltered ground vegetable soil increases along with the increase of soil depth,but the calcium content's change has no rule.There is negative correlation between organic matter content and calcium content;there is positive correlation between soil PH value and calcium content;there is remarkable negative correlation between vegetable output and calcium content. |

| Keywords: | vegetable soil calcium content changing rule |
