回顾创新灌溉节水策略来改善水和产生生产力的洋葱

文摘

全球人口爆炸,我们的自然资源基础正在下降。为了养活这些人,全球粮食产量的增加,特别是在较贫穷的国家,无疑是必需的。农村人口的主要收入来源小农农业。降雨在旱作农业、不可预测性和不一致性是主要挑战和小农是特别容易受到作物生产。灌溉对农业产出至关重要,因为它可以减少降雨可变性和不一致。然而,灌溉用水变得更珍贵的资源在世界各地,和用水效率低,加之水资源的日益激烈的竞争,促使种植者采用新颖的灌溉和生产策略,节约用水。因此,覆盖物和亏灌溉是两个广泛使用节水提高作物的水分生产力的解决方案在水资源缺乏的地区。结果,新的想法需要改善水的效率有限。亏灌溉和覆盖方法可以用来制造更好、更有效地利用有限的水供应。自然资源的有效和具有成本效益的使用通过低成本的解决方案,比如覆盖物和赤字灌溉是明智的和自适应最大限度地提高作物产量,降低生产成本。 In arid climates, combining mulch with appropriate deficit irrigation to raise crop yield and water productivity is an effective strategy to establish a good trade-off between water use and production, as well as improve water productivity. Deficit irrigation and mulching will become more important in locations where available water supplies limit agricultural production, to maximize the productivity of their limited water resources. Farmers, on the other hand, must carefully select irrigation systems and water-saving technology to maximize yield and water productivity.
