摘  要:
豫西旱农区水资源严重匮乏 ,年降水量偏少 ,季节分布不均 ,年际变率大 ,干旱灾害频繁 ,且持续时间长 ,水资源短缺已成为制约豫西旱农区农业可持续发展的关键因素。要改善豫西旱农区缺水等不利的自然条件 ,就必须在探明其水资源面临问题的基础上 ,探索旱作农业抗旱节水的有效途径。笔者认为 ,选用耐旱作物和抗旱品种 ;广泛采用各种抗旱节水农艺措施 ;大力推广降水集存技术、节水灌溉及化学抑蒸技术 ,才能有效地提高水资源的利用率和利用效率 ,保证豫西旱农区农业的可持续发展

摘  要:
Water resources were heavily insufficient ,annual precipitation was few and unbalanced in different seasons , annual gradient has larger change and drought frequently appears and lasts for a long time in western Henan.The insufficiency of water resources was a major factor that constrainted the sustainable development of agriculture in arid planting areas.To improve the problem of drought ,water shortage and.unfavourable condition,it is necessary that investigate effective measures of drought-resistant and water-saving to present water resource situation:applying suitable crops and cultivars,and agronomic measures of drought-resistant;popularizing techniques of rainwater harvesting ,water-saving irrigation and chemical evaporation-restrained ; raising water utilization efficiency;ensuring the sustainable development of agriculture in arid planting areas in western Henan.
