潮土区不同质地类型土壤对酸缓冲性能的研究

Studies on Acidic Buffering Capacbility in Different Soil Texture Types in Moisture Soil Area

对新乡潮土区不同质地类型土壤酸缓冲性能的研究表明,粘土的缓冲能力最强,砂土的缓冲能力最弱。缓冲能力的大小与土壤中物理性粘粒含量成正相关,相关系数为0.983,达到了0.01显著水平。不同质地类型土壤的酸缓冲能力大小为:粘土>中壤土>轻壤土>砂壤土>砂土。试验结果还表明,土壤有机质含量与土壤酸缓冲能力无明显的相关性。

Studies on the acidic buffering capacbility in different texture types in Xinxiang area, showed that acidic buffering capacities of clay .soil is larger than sandy soil. The relation between physical clay and acidic buffering capacbility is a positive correlation with correlation coefficient of 0.983. The acidic buffering capacbility in different texture soils in the north China plain is clay soil〉medium loam soil 〉 light loam soil 〉 sand loam soil 〉 sand soil.
