摘　　要：基于吉林省淡黑钙土地区玉米秸秆还田低效率的状况,采用恒温培养方法,研究玉米秸秆还田配施硫酸铝改良剂对土壤培肥改良效果。结果表明,玉米秸秆和硫酸铝改良剂的添加对土壤固定有机碳具有促进作用,玉米秸秆和硫酸铝改良剂的添加对土壤p H值和碳酸盐含量具有降低作用,其中,硫酸铝改良剂添加对两者的影响起到了主导作用,而秸秆次之;秸秆和硫酸铝改良剂的添加对土壤阳离子交换量也有一定的提升作用,且土壤中有机碳含量与阳离子交换量呈显著正相关。Based on the situation of inefficient corn straw returning in light chernozem region of Jilin province, by the incubation method, the effect of adding the straw and aluminum sulfate to soil to improve soil fertility was studied. The results showed that adding corn straw and aluminum sulfate to the soil was good for increasing the car- bon content, adding corn straw and aluminum sulfate to the soil can reduce the soil pH value and carbonate content, which aluminum sulfate played a leading role, while straw took second place, adding corn straw and aluminum sul- fate to the soil was good for increasing the soil CEC, while soil organic carbon content and cation exchange capacity were a significant positive correlation.
