为研究传统耕作方式下连续秸秆全量还田对土壤理化性状的影响，通过对8年田间定位试验的大田土壤研究常规施肥和秸秆全量还田2种处理对土壤密度、孔隙度和土壤有机质、有效磷、速效钾的影响。结果表明，秸秆全量还田不仅能改善土壤物理性状，还能显著提高土壤的养分状况，相比对照土壤有机质、有效磷、速效钾分别提高了6.7 g/kg、2.6 mg/kg、33.1 mg/kg，对耕地质量管理和提升具有积极意义。

In order to study the effect on continuous total straws returning to field on soil physical and chemical properties under conventional tillage, the long-term located trials with eight years were conducted to study effect of two measures with conventional fertilization and total straws returning to field on soil bulk density, porosity and soil organic matter, extractable phosphorus, available potassium in soil. The results showed that the total straws returning to field could improve physical properties in soil, and also increase the contents of nutrients in soil significantly. Compared to the control, the content of soil organic matter, extractable phosphorus, available potassium increased by 6.7 g/kg, 2.6 mg/kg and 33.1 mg/kg, respectively, and it was a positive meaning for management and improvement of the farmland quality.
