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。
The results showed that the nutrient levels of acidic soils in mountainous yellow soil were very low, and the lack of trace nutrients was mainly due to the high content of aluminum and iron ions in the soil. The application of lime could increase the pH value of soil, Reduce the soil exchangeable aluminum and plant iron, manganese content, can make white clover potassium level increased.
