摘要

为了研究唐山市滨海泥质盐碱地不同隔离措施台田水分和盐分动态

于2009年对不同隔离层措施的台田水分和盐分含量进行了分析和研究。结果表明

试验地台田水盐动态可分为积盐阶段、脱盐阶段和返盐阶段;土壤水分与盐分含量呈负线性相关关系

在4-10月份间

土壤盐分呈先降低后升高趋势

水分呈先升高后降低的趋势;由铺设隔离层的台田深层土壤电导率值和土壤水分明显低于对照台田可以得出

隔离层具有明显的阻盐和排水效果

其中

隔离层铺设方式为"双条一杠"型

铺设内容为炉渣的台田阻盐效果最佳

由于其成本较低

所以应大力推广使用。

Abstract

In order to research the water-salt dynamic of platform fields by different isolation measures in coastal argillaceous saline land of Tangshan City

the salt content and water content of platform field by different isolation measures in 2009 are analyzed.Results showed that

water-salt dynamic of platform can be divided into three stages which were salt accumulated

desalinization and resalinization.There was a negative linear correlation between the water content and salt content

from April to October

the soil salt content showed a trend of "up-down"

but the water content showed the opposite trend.The fact that the soil conductivity and water content of platform field which used isolation layer were lower than comparison platform field indicates that the isolation layer has obvious effect of salt resisting and draining.The best salt resisting isolation layer is that paved in the pattern of "double-section and a bar"

and with slag

it should be widely used for its low cost.
