| 摘 要： | 以松辽平原玉米带高产土壤和平产土壤为研究对象,研究了不同玉米产量土壤微生物量碳的变化特征及其与土壤理化性质、玉米产量的相关性.结果表明:高产培育模式下,土壤微生物量碳、微生物商显著增加;土壤微生物量碳与土壤有机碳、全氮显著正相关(P<0.05),与有效磷、>0.25 mm团聚体数量及平均重量直径极显著正相关(P<0.01),与土壤容重显著负相关(P<0.05),与pH、结构破坏率极显著负相关(P<0.01),与玉米产量极显著正相关(P<0.01).由此可见,土壤微生物量碳是反映玉米高产培育模式下土壤肥力变化的重要指标.

| Abstract: | The change of microbial biomass CARBON and the relation between microbial biomass carbon and physiochemical properties of corn soil in Songliao Plain were studied.The results indicated that microbial biomass carbon and microbial quotient of high yield soil are significantly higher than those in the normal yield soil under high yield culture pattern.Microbial biomass carbon has a significantly positive relation with the orgnic carbon total nitrogen(P<0.05),available phosphorus,amount of aggregate(>0.25 mm),m... |
