摘要：

采用“脱硫废弃物施用＋平整土地＋深松耕＋水盐调控＋平衡施肥＋耐盐作物种植”的盐碱地改良技术集成模式在惠农核心试验示范区开展盐碱地改良技术集成示范，经过两年的改良，示范区地下水位下降了50 cm左右，土壤总盐及有害盐分离子含量也有了较大幅度的下降，油葵出苗率和产量显著提高，出苗率为70%以上，平均产量为1534.3 kg/hm2，示范区水土环境有了较大的改善，表明以脱硫废弃物施用为切入点的盐碱地改良技术集成模式对轻度碱化盐荒地具有良好的改良效果。

Abstract:

Applying the technology integration pattern of ‘desulfurization waste application + land leveling + deep ploughing + salt and water regulation + balanced fertilization + salt-tolerant crop planting’ to Huinong core experiment and demonstration area to improve saline-alkaline land, two years later, the water and soil environment of the demonstration area took place greate improvement. The groundwater table decreased 50 cm or so in demonstration area. The soil salt content and harmful salt ions content dropped drastically in demonstration area. The emergence rate of oil sunflower increased to more than 70%, and the yielding of oil sunflower reached to 1534.3 kg/hm2. The results showed the pattern that takes desulphurization waste application as cut-in point to improve saline-alkaline land had a good effect on the mild-alkaline salt wasteland.
