“污水”灌溉不是指用受到污染的水体进行农业生产活动,而是将进行处理达到灌溉水质量标准的水源,用于农业生产的基本活动,如灌溉农作物等。由于城市排放的污水含有大量的氮、钾等养分,水体中富含有机悬浮物,这些污水对于农田来讲是重要的肥料,用城市污水进行农田灌动,在提高土壤费肥力的基础上,对于降低农业生产成本有着重要影响。基于此,主要采用SWOT方法对“污水”灌溉进行分析,对于灌溉中存在的问题提出了解决的方法。 “Sewage” Irrigation does not refer to agricultural production using contaminated water, but rather to water sources that meet the quality standards for irrigation water and basic activities for agricultural production such as irrigation of crops. Because the city sewage contains a lot of nitrogen, potassium and other nutrients, the water is rich in organic suspended matter, the sewage is an important fertilizer for the farmland, with urban sewage irrigation, on the basis of improving soil fertility, Have a significant impact on reducing agricultural production costs. Based on this, the SWOT method is mainly used to analyze the “sewage” irrigation, and a solution to the existing problems in irrigation is proposed.
