摘要
黄土高原属典型雨养农业地区 ,干旱缺水是制约该区旱作农田生产力进一步提高的瓶颈。然而 ,大量试验研究表明 ,严重的水土流失和无效蒸发则是造成旱地作物产量低而不稳的根本原因。近年来 ,各地在农田蓄水、保水、集水、补水和用水等方面 ,研究成功许多行之有效的旱作农田降水资源高效利用新技术 。
In the typical rain fed farming areas of Loess Plateau, drought and water shortage are the main choke points to the increase of farmland productivity. However, it has been proved by numerous experiments that the severe erosion and the impotent evaporation are the main reasons causing the low and unstable yield of crops. During the past years, many new techniques of water storage, conservation, harvesting and utilization with high efficient utilization of precipitation resource on dry farming lands have been investigated successfully in various regions, showing the large potential and vast foreground of agricultural development in Loess Plateau.
