| 摘 要： | 通过对胶东地区果园土壤的采样化验,并与全国第二次土壤普查的数据对比分析,结果显示,果园土壤酸化程度明显高于第二次土壤普查和农田土壤,果园上层土壤pH和潜性酸低于下层,酸化明显。化肥的过量施入、有机肥施用不足、大水漫灌的灌溉方式是加剧果园土壤酸化的主要原因。

| Abstract: | In order to know the characteristic of orchard soil acidification in the area of Shandong Peninsula,some soil samples were analyzed.The results showed that the orchard soil acidification was very strong,soil pH value of orchard was far lower than the value of soil survey in 1981 and that in farmland,and the pH and potential acidity of top soil in orchard was lower than that of subsoil.The cause of orchard soil acidification in the area of east Shandong province focused on the increasing input of chemical fertilizer,decreasing input of organic fertilizer and flooding irrigation. |

| Keywords: | soil acidification chemical fertilizer organic fertilizer flooding irrigation |
