摘　　要：对贵州南部低ｐＨ牧地施用石灰，试验结果表明：山地黄壤酸性土壤植物营养水平都很低，同时微量养分缺乏，主要是由于土壤铝、铁离子高的影响，施石灰可增加土壤ｐＨ值，降低土壤交换性铝和植物中铁、锰含量，能使白三叶含钾水平提高。A study on liming of low pH grazing land was performed.The result showed that nourishment level ofplant was very low and trace nourishment deficiency in acid sofis, which is that Al,Fedsoils are high.Liming will increase soil pH value and decrease Al-exchange in soils and Fe,Mn contents in plant andincrcase K content of white clover.
