摘要
水质分析对于微灌系统的设计和运行管理至关重要,但目前国外的微灌水质标准不尽统一,我国还没有较为完善的微灌水质标准,导致在实际工程中微灌水质分析没有得到足够的重视。从微灌水质不满足要求容易引发的堵塞、土壤碱化、土壤渗透性降低、作物敏感性、离子毒性等问题入手,详细分析了各种问题对应的水质分析参数,并结合国内外相关经验,提出了微灌水质分析指标体系。
Water quality analysis is very important for the design, operation and maintenance of micro-irrigation system. However, at present, there is no one unified water quality standard for micro-irrigation system in the world, and there is no one comprehensive standard in China, so water quality analysis is not given enough attention in actual project. Starting with some problems caused by unqualified irrigation water, such as clogging, soil basification, soil permeability decrease, crops sensitivity, and ion toxicity, the author analyzed the water quality analysis parameters correspond to each problem and put forward a water quality analysis indexes system for micro-irrigation .
