采用田间小区试验方法研究了玉米秸秆和根茬留田对土壤生化环境因子的影响。结果表明:玉米秸秆和根茬留田可增加土壤微生物量碳的含量,较对照和单施化肥土壤微生物量碳分别增加38.4％～84.9％和27.2％～51.6％;增强土壤pH值的缓冲性能;改善土壤团聚体结构;有利于土壤中氮、磷、钾、铜、锌、铁、锰等养分的释放与调控,为作物生长创造适宜的土壤生化环境。 Field experiment was conducted to study the effects of corn stalks and root stubble on soil biochemical and environmental factors. The results showed that soil microbial biomass carbon increased with corn stalks and root stubble soils increased by 38.4% -84.9% and 27.2% -51.6%, respectively, compared with the control and single-applied chemical fertilizers. Soil buffering properties of soil pH were enhanced. Improve the structure of soil aggregates; help release and regulation of nitrogen, phosphorus, potassium, copper, zinc, iron, manganese and other nutrients in the soil, and create suitable soil biochemical environment for crop growth.
