Abstract: 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.
