摘　　要：由于淡黑钙土有机质含量低,碳酸盐含量较高,土壤肥力相对较差,因此为保证粮食的稳定增产,需对土壤进行改良,提升土壤肥力的主要措施是向土壤中添加有机物料,而有机物料的添加会影响碳酸盐的平衡。试验以淡黑钙土为研究对象,探讨添加有机物料对碳酸盐的影响。结果表明:有机物料的添加使土壤pH、HCO_(3)-均有不同程度的提高;随着培养时间的增加,有机无机肥配施土壤碳酸盐含量升高,添加玉米秸秆处理的土壤碳酸盐含量下降;施用秸秆能有效提高交换性Ca^(2+)、Mg^(2+)、K^(+)、Na^(+)含量,施用有机无机肥降低了交换性盐基中交换性Ca^(2+)、Mg^(2+)含量,提高了K^(+)、Na^(+)的含量。Light chernozem is the main soil resource in Jilin province.Due to its low organic matter content,high carbonate content and relatively poor soil fertility,the main measure to ensure the stable increase of grain yield and improve soil fertility is to add organic materials to the soil,and the addition of organic materials will affect carbon balance.Light chernozem was selected to explore the effects of organic materials on the change of carbonate.The results showed that soil pH and HCO_(3)-were increased with the addition of organic materials.With the increase of incubation time,the content of soil carbonate was increased with the combination of organic and inorganic fertilizers,while the content of soil carbonate decreased with the addition of corn straw.The content of exchangeable Ca^(2+),Mg^(2+),K+and Na+could be effectively increased with the application of straw.The application of organic and inorganic fertilizers reduced exchangeable Ca^(2+)and Mg^(2+)content,and increased K+and Na+content in exchangeable base.
