灵正灌区节水思路探讨

Discussion on water saving ideas in Lingzheng irrigation areas

现代农业的发展对灌区提出新的要求,在实施灌区续建配套和改造中,需要分区域、成规模地采取节水措施。论述了现代灌区节水的意义,通过实施节水灌溉,最大限度地提高灌溉效率。从灌溉治理中的水资源短缺、灌溉设施更新、信息化发展需要、生态功能性较差等突出问题展开介绍;从选择原则、渠道防渗、管道输水灌溉、喷灌、滴管、膜下灌溉6种节水灌溉方式,来探讨现代灌区节水思路。结合地域特点,选择合适的节水灌溉方式,从而促进灌区稳定高产。

The development of modern agriculture puts forward new requirements for irrigation districts,and in the implementation of irrigation renewal and renovation,it is necessary to take water-saving measures on a regional scale.This paper first discusses the significance of modern irrigation district water conservation,through the implementation of water-saving irrigation,to maximize irrigation efficiency.it introduces the outstanding problems in irrigation management,such as water shortage,irrigation facilities need to be updated,the need for information technology development,and poor ecological functionality;finally,it discusses the water-saving ideas in irrigation areas nowadays from the six water saving irrigation methods,such as the principle of selection,channel seepage prevention,pipeline irrigation,sprinkler irrigation,drip pipe,and under-membrane irrigation.Combined with the regional characteristics to choose the appropriate water-saving irrigation methods,to promote stable and high yield.
