于１９７９～１９９４年在草甸暗棕壤上进行定位田间试验。结果表明，麦秆直接还田可以增加土壤有机质和改善土壤物理性状；麦秆直接还田与化肥配合时，才能获得高产稳产。
Field experiments were conducted on meadow dark brown soil from 1979 to 1994. The results showed that straw returning directly to the soil could increase soil organic matter and improve soil physical properties. When the wheat straw was returned directly to the field with fertilizers, the yield was stable.
