中文摘要:
      基于多年的节水农业试验实践,分析了粮田关键节水技术及其节水潜力,集成了7种粮田节水模式,其中以调亏灌溉、秸秆覆盖、少耕覆盖等农艺节水技术为主的综合节水模式的水分利用效率比对照模式提高12%~21.3%,适合华北井灌区一般经济条件的区域推广。
英文摘要:
      Based on many-year field experiment results of water-saving agricultural technology, we integrated seven water-saving models, the model three and model four were built up by some agronomic water-saving technologies, such as insufficient irrigation method, straw mulching, shallow tillage and so on. The WUE (water use efficiency) of model three and model four improved 12%~21.3% comparing with CK model. Model three and model four could be applied in all irrigation regions using groundwater in North China.
