| Abstract: |
| The activity of no-tillage-based sand control is carried out in Beijing and its surrounding areas against the problems of sand dust weather and desertification．Based on the investigation of the experimental field and visit to peasant households the present paper systematically compares the input and output of no-tillage and traditional tillage evaluates the benefit when no-tillage is fully operated in Beijing．The results show that compared with traditional tillage the input of corn under no-tillage decreases by1016Yuan RMB per hectare and the input of wheat under no-tillage decreases by 921 Yuan per hectare．Meanwhile the crop yield of corn under no-tillage increases by864kg per hectare and the crop yield of wheat under no-tillage increases by 209 kg per hectare．The implementation of no-tillage to corn increases benefit by 2030 Yuan per hectare and that to wheat increases benefit by 1215 Yuan per hectare．The input output and benefit of no-tillage implementation have certain regional difference the best comparative benefit is showed in the region of spring corn growing with one crop in one year．This research can provide theoretical references for the extension of no-tillage implement and researches related to agricultural economy in Beijing and its surrounding areas． |
