| 摘 要： | 利用西南地区6种土壤进行人工酸添加实验。结果表明 ,土壤在负荷了酸添加后 ,土壤 pH下降且Mn的析出增加。但Mn的析出因绝对量较低 ,对植物生长没有表现出毒性。因重庆和贵阳的土壤背景值Mn含量较低 ,可以忽视Mn毒性。

| Abstract: | An experiment using 6 kinds of soils from southwest region of China fortified with acid were investigated. It has been found that decline in the soil pH and increase in leaching of Mn with acid addition were observed. However, absolute volume of leaching of Mn was low, Mn toxicity on the growth of plants were not observed. The background volumes of Mn of soils in Chongqing and Guiyang both were low and may be overlook the toxicity. |
