摘要

采用短期室内中水灌溉土柱模拟和长期中水灌溉区大田定位调查

对中水灌溉后对植物体内营养元素、毒害离子以及重金属的增减变化进行对比分析。结果表明

与清水对照相比

中水灌溉使绿地土壤pH值降低

土壤有机质含量增加

孔隙度增大

容重及田间持水量减小;全氮、全磷含量随土层厚度的增加而呈减少的趋势;碱解氮、有效磷和速效钾含量增加且与清水对照之间差异显著(P<0.05);盐离子在土壤中得以积累

含量增加;毒害离子和重金属含量呈增大或减少的趋势

与不同离子种类有关

但其含量极少

累积效应变化缓慢

且由于自然降水等因素的稀释和植物、土壤微生物等因素的吸收及降解

一般不会造成对土壤的污染及对植物的生长胁迫。

Abstract

Adopt short-term indoor reclaimed water irrigation in the soil column simulation and long-term field investigation

identify positioning

for reclaimed water irrigation to plant nutrients mischief ion and heavy metal element

and decrease of change were compared and analyzed.Results showed that

with clear-water contrast

reclaimed water irrigation made greenland soil pH lower

soil organic matter content increased

porosity increased

density and field capacity decreased;Total nitrogens

total phosphorus content wi...
