摘要

通过大田试验

研究了冬季咸水结冰灌溉及覆膜对天津滨海盐碱地水盐运移的影响

以期揭示从结冰融化到雨季之前植物萌发生长关键时期的水盐变化.结果表明

咸水结冰灌溉能降低根层土壤含盐量

增加土壤含水量

且灌溉水量越大效果越明显

但春季大风干燥天气

使土壤水分快速蒸发

土壤表层迅速积盐

5月份之后不同处理间差异已经不显著;覆膜能够有效抑制水分蒸发和表层盐分的累积

T4和T5含水量分别比CK和T2高出10.04%和16.51%

表层电导率分别低38.63%和36.82%(4月7日);同时

结冰灌溉和覆膜也提高了土壤pH值

且与对照之间差异达到显著水平.因此

结冰灌溉配合覆膜可以有效降低水分损失

维持土壤低盐水平

为早期植物萌发生长提供有利条件

但同时也应注意因此而带来的土壤碱化问题.
