- 摘要:
- 水分是影响西北黄土高原地区农业生产的限制因子。雨水资源则是该地区农业生产的主要水源，因而在广大的干旱半干旱地区充分利用有限雨水资源显得尤为重要。若能在现有的条件下，将领先的农业高新技术和传统的集水经验有机地结合起来，在广大的干旱半干旱地区，从“全拦降水，就地入渗，高效利用”天然降水入手，改革耕作制度，实行覆盖技术，减少地面蒸发，探索出一条符合当地实际的科学有效的“雨养农业”的新路子。这既是保证当地居民食物供应的需要，也是为西部大开发奠定稳固的农业基础。
- Abstract:
- Water is a restricting factor to agricultural production in the northwest Loess Plateau.Rainfall is the significant water resource to this area.Therefore, fully using the limited rainfall resource seems more important.If the advanced agricultural technique could be combined with traditional water collection experience closely, to start the work from "collecting rainfall fully, infiltrating to the fields quickly, and using it efficiently", reforming the old tillage system, reducing evaporation by field covering, a scientific and efficient new way of "rain fed agriculture" that suits with local fact is found.This is not only the guarantee of the food supply for the local people, but also the firm agricultural foundation in developing the west of China.
