| 摘要: |
| 1984～1987年在陕西省渭北旱原进行耕作法对比试验的结果表明,深松法和残茬覆盖深松法较翻耕法,在夏闲末两米土层内分别多蓄水14.04,35.14mm,小麦增产8.O％和20.0％。铁牛55牵引深松机深松比三铧犁翻耕,油耗降低25％,生产效率提高41.8％,具有推广应用价值。 |

| Abstract: |
| The comparative experiments of tillage methods were conducted in the years 1984-1987 on weibei Rainfed Highland in Shaanxi Province, The experiment results showed; the moisture stbred in 0～200 cm soil 1ayer of summer fallow land at the end of rainy season is 14.04mm and 30.l4mm more in soil by subsoiling tillage and mulching tillage as compared with that by ploughing tillage with an average increase of 8.0% and 20.0% respectively .And feul consumed by subsoiler drawn by Iron Cattle NO:55tractor is 25% lower than that by tri-share plow with working efficency going up by 41.8% so that new tillage method is of great value in extension and utilization. |
