摘要:
针对江苏海涂垦区滩涂盐碱地成陆时间短、土壤贫瘠、含盐量高、地下水埋深浅等特点,开展在暗管控制排水条件下沿海垦区土壤盐分运移规律的研究。通过不同间距暗管布设及排水控制,对土壤盐分变化、作物产量及水、盐运移规律进行了分析研究,初步探明了海涂垦区土壤水盐运移的规律。结果表明:暗管间距、测点至暗管的水平距离2 个变量与土壤含盐量变化的速率呈负相关;暗管排水能有效地控制地下水埋深,降低土壤表层盐分,增加作物产量。
Abstract:
The saline-alkali land soil in the coastal reclamation area is poor, high salt content, short time of continent formation and shallow groundwater, According to the characteristics above, the soil salinity movement regularity in coastal reclamation area under subsurface pipe drainage was studied. By way of the layout on underground pipes with different spacing and drainage control, the changes of soil salinity, crop yield and water and salt transport regularity was researched, the water and salt movement regularity of the soil in coastal reclamation area was ascertained preliminarily. The results indicated that the under subsurface pipe distance and the horizontal distance between the measure point to the pipe are negatively correlated with the change rate of soil salt content,and subsurface drainage can effectively control groundwater depth, reduce soil surface salinity, and increase crop yield.
