摘　　要：研究表明,长期定位试验下白浆土pH值,除有机肥处理外,均较开垦初期有一定程度下降。并以大豆连作降低最为明显。有机肥具有明显提高土壤pH值的作用。长期免耕与深松对土壤pH值影响差异不大,但二者均略低于平翻处理。The results showed that the soil pH was decreased, especially in soybean continuous cropping. But soil pH could be increased by applying organic ferilizer in Albic soil under long-term localized test. The difference of pH between non-tillage and deep-tillage was not significant, and they were lower than conservation tillage.
