1添加玉米和水稻秸秆对淹水土壤pH、二氧化碳及交换态铵的影响显示文摘通过温室土壤培养试验,研究了不同添加量玉米和水稻秸秆对淹水土壤pH、CO2及交换态铵的影响.结果表明:在接近中性的土壤中加入秸秆可使土壤pH值降低,4g.kg-1玉米和水稻秸秆处理的土壤pH值均与对照差异显著(P<0.05),而1g.kg-1玉米和水稻秸秆处理与对照差异不显著(P>0.05).土壤溶液中的CO2含量随秸秆添加量的增加而增大,1g.kg-1玉米和水稻秸秆处理的土壤溶液CO2含量最大值分别为35.9%和31.9%(v/v),与对照(25.8%)差异达显著水平(P<0.05),但两者间差异不显著(P>0.05);4g.kg-1玉米和水稻秸秆处理的土壤溶液CO2含量最大值分别为54.2%和41.8%(v/v),与对照差异极显著(P<0.01),两者间差异也达显著水平(P<0.05).在不施氮肥的情况下,添加秸秆可降低土壤铵态氮浓度,且铵态氮浓度随秸秆添加量的增加而降低,不同添加量处理间差异显著(P<0.05);在施入氮肥的情况下,1g.kg-1玉米和水稻秸秆处理提高了土壤铵态氮浓度,而4g.kg-1玉米和水稻秸秆处理降低了土壤铵态氮浓度.无论是否施入氮肥,玉米和水稻秸秆处理的土壤铵态氮浓度差异不显著(P>0.05).叶文培 王凯荣 Johnson SE 谢小立 2008应用生态学报2008,19,2:20
