摘要

北方半干旱区农业灌溉用水紧缺、水分利用效率偏低，传统灌溉模式易引发水肥流失与土壤退化，制约旱作农业 稳产增效。为探究磁化水灌溉的田间应用价值，本文以大田定位试验为依托，设置常规灌溉为对照组，系统探究磁化 水灌溉对农田土壤水分、作物产量及土壤性状的影响。试验结果表明，磁化水灌溉可有效提升耕作层土壤含水率，减 少田间无效水分损耗，较常规灌溉增产 9.66%，同时可优化土壤孔隙结构、改善土壤板结问题。该节水技术兼具经济 性与生态性，适配北方旱区种植条件，可为区域农业节水提质、耕地可持续利用提供技术参考。

Abstract

 In the semi-arid regions of northern China, agricultural irrigation water is scarce and water use efficiency remains relatively low. Traditional irrigation modes are prone to causing water and fertilizer loss as well as soil degradation, which restricts stable yield and efficiency improvement in dryland agriculture. To explore the field application value of magnetized water irrigation, this paper conducts a systematic study based on a field positioning experiment, with conventional irrigation set as the control group, to investigate the effects of magnetized water irrigation on farmland soil moisture, crop yield, and soil properties. The experimental results show that magnetized water irrigation can effectively increase the soil moisture content in the cultivated layer and reduce ineffective water loss in the field. Compared with conventional irrigation, crop yield increased by 9.66%. Meanwhile, magnetized water irrigation can optimize soil pore structure and improve soil compaction. This water-saving technology has both economic and ecological benefits, is suitable for planting conditions in northern dryland areas, and can provide technical references for regional agricultural water conservation, quality improvement, and sustainable use of cultivated land.
