潮土和石灰性褐土缓冲性能研究

Studies on Buffering Action of Chao Soil and Lime Drab Soil

对豫北地区的 2个土类 3种不同土壤的缓冲性能进行分析研究 ,结果表明 :供试土壤对酸、碱的缓冲性强弱依次为高肥潮土 >褐土 >潮土。且对酸的缓冲能力强于对碱的缓冲能力。此外 ,土壤有机质含量的高低与其对酸碱的缓冲能力成相关。

Analysis on the buffer action of three kinds of different soils from two soil types of the north of Henan,showed that the order of buffer action acid and alkali of three kinds of different soils was as following: chao soil with high fertility>lime drab soil>chao soil.Among them,the acid buffer action is stronger than the alkali buffer action.The organic matter content of soil is relative with the buffer action of acid and alkali of soil.
