摘要
本文根据目前微灌系统存在的堵塞问题,从以下四个方面提出了微灌对水质的要求,1.水的混浊度;2.盐渍度;3.铁、硫、碳酸钙的含量;4.水中微生物的总量。同时,并就我国部分微灌工程进行了实地调查,对不同水源分别采集了水样,并进行了常规分析和评价。
According to the clogging of micro-irrigation, systems in China, the following four requirements for water quality are put forward: 1. water turbidity; 2. salinity; 3. the content of iron, sulphur and calcium carbonate; 4. total micro-biological content. At the same time, the authors have expedited some micro-irrigation projects, collected some water samples from different water sources and made normal analyses and evaluation.
