农业节水主攻方向探讨

The Probing of Main Direction of Agricultural Water Conservation

解决北方地区水资源危机问题的关键,是在现有的大中型引河水的灌区内打井,按照以井灌为基础、引地表水补源的原则进行技术改造和加强用水管理。井灌区应采取农业综合节水技术体系,保持在一个水文周期内地下水采补基本平衡。喷灌是先进灌水技术,有许多优点,但也有许多限制条件,推广应因地制宜,尊重群众意愿。

The key of solving the water shortage problem in the northern part of China is to use well -irrigation in the large -sized irrigation Districts. Technical renovation and strengthening water-use management should be adopted in line with the principle of basing on well irrigation and making up by surface water. Agricultural Comprehensive water saving technology system should be adopted for the well-irrigated area and the basic balance remained for extraction and recharge during one hydrological circle. Sprinkler irrigation is an advanced irrigation technology despite its disadvantage.
