| 摘 要： | 研究表明,冀西北高原水资源较为匮乏,但浪费严重。6月中旬为该区气候稳定干旱期,7月上旬～8月下旬为稳定湿润期。春小麦生育耗水与自然降雨供水错位,拔节～抽穗期为需水临界期,亦为补水关键期。根据春小麦耗水量与水分供需平衡分析拟定了春小麦节水高产灌溉制度:一般年补水120mm;干旱年补水150mm;丰水年补水90mm;特旱年补水180mm。

| Abstract: | Studies showed that water resource in north west plateau of Hebei Provincewas shortage, but wasted seriously on the other hand. The climate in this region wasat stable arid period in the mid June, and humid from first ten days of July to last Au-gust, Demanding and supplying of water in spring wheat was unconnected, The key pe-riod of water irrigating, as a critical period of water demanding, was at from jointingstage to heading stage. Based on water consumption and analysis of demanding and sup-plying equation of water, the irrigation regime of water saving and high yielding hadbeen worked out sa follows: generalyears, 120mm; arid years, 150mm; rainy years,90mm; specially arid years, 180mm. |
