节水型农业是以节水高产为中心,以提高作物的水分利用效率为目的,并保证水资源系统的良性循环为条件的农业。它主要研究解决节水高产、水资源供需平衡、输水灌水、农田蒸发和作物蒸腾中的‘理论和应用技术问题。本文以南皮节水农业综合试点为例,系统阐述了上列问题,供在不同类型区开展节水农业的研究和试点参考。
Water-saving agriculture is based on water-saving and high yield as the center, to improve the water use efficiency of crops for the purpose, and ensure the healthy recycling of water resources system for the conditions of agriculture. It mainly studies and solves the theoretical and applied technical problems in water-saving and high-yielding, water supply and demand balance, water conveyance, farmland evaporation and crop transpiration. In this paper, a comprehensive pilot project of water saving agriculture in South bark is taken as an example, and the above problems are systematically expounded for the research and pilot reference on water-saving agriculture in different types of areas.
