| 摘 要： | 随着微咸水灌溉面积逐年增加，不合理的灌溉对土壤环境造成了不同程度的污染。该文采用大型蒸渗仪研究不同地下水埋深条件下微咸水灌溉夏玉米对土壤-作物系统环境因子的影响。研究结果表明：在地下水水位低于3 m地区进行微咸水灌溉，0～100 cm的土层内不会形成严重的积盐现象。当灌水水质为4 g/L时，灌水水质对土壤盐分环境的影响大于地下水埋深对其的影响。地下水埋深越深，夏玉米叶面积指数、株高及产量越小，且随灌溉水盐分水平的增加而减小，地下水埋深对夏玉米形态指标的影响大于盐分水平对其的影响。

| Abstract: | The area of brackish water irrigation has become increasingly year by year. Soil environment has been polluted in different degrees by illogical irrigation. In this paper, the effects of brackish water irrigation on the environment factors of soil-crop system under different groundwater depths were studied. The experiment was carried out in a lysimeter. The results showed that salinity accumulation did not appear in 0-100 cm soil layer when irrigated by saline water in the area of groundwater depth below 3 m. The effect of irrigation water quality on soil salinity was more significant than groundwater depth when salt concentration of irrigation water was 4 g/L. The deeper the groundwater depth was and the higher the salinity level was, the less the leaf area index, height of plant and yield were. And the effect of groundwater depth on morphological index was more significant than salinity level. |
