摘要
水资源紧缺巳成为全球突出问题之一,国内外对研究节水灌溉都给予高度的重视,但大多数都是从单项内容进行研究,如节水灌溉技术、充分利用雨水、保水农业栽培措施等都取得了一定成效和生产效益。我们认为:节水农业就是充分利用降水和当地水资源,水利措施与农业措施紧密结合以提高水的利用率和水的利用效率。也就是灌溉农业和旱地农业相结合。针对不同的农业生产类型区采取不同的技术措施,从而得出不同的农、水措施优化体系,在中国农科院商丘666.7ha(万亩)节水农业试验区进行了四年的试验与推广,取得了综合节水6％、增产8％的效益。对指导缺水地区生产和宏观控制水、土资源合理开发利用具有现实的意义。
Water-saving technology is an engineering system for comprehensively exploiting and managing water and soil resources. Throughtout 4 years' experiments and based on different water resources, agrotechnical levels, soil fertility and irrigation condition, different systems have been classified as follows:(Ⅰ) high-yielding irrigation;(Ⅱ) limited irrigation;(Ⅲ) anti-drought irrigation; and(Ⅳ) upland agriculture.An integrated water conservation measure for agricultural production has been developed over a 667-ha water-saving region, where the grain production and water efficiency have been increased respectively.
