| 摘要: |
| 在缓坡坡耕地农业生产中存在着应选择横坡垄还是应选择顺坡垄问题。重点分析了它们对农业经营的利弊和它们在生产过程中的演变。调查表明二者水土流失均较严重,只是侵蚀方式不同。提出了既适合横坡垄又适合顺坡垄水土保持的措施---垄向区田及其配套农具---1QD型垄向区田筑挡机。 |

| Abstract: |
| There is existing a problem which can be the best way to conserve the soil and water at flat gradient crop land.Is it the cross ridge or longitudinal ridge? we emphases on analyzing the pros,cons and evolution of both ridges,and research a low cost practice with its mechanical equipment.It is sautible for either cross ridge or longitudinal ridge. |
| Key words: cross ridge longitudinal ridge w ater loss and soil erosion |
