摘　　要：田间防渗措施对于新增水田的建设质量和建设成本至关重要。为探寻适宜的田间防渗措施并节约投资,在安徽省阜阳市阜南县田集镇项目区内选定一块具有典型性的田块作为试验地,分别采用机械碾压,以及添加碳酸氢铵、防渗漏剂等多种措施进行处理,随后进行保水试验对比研究。试验结果表明,机械碾压能够有效降低水分的渗透速率,当压实度达到81%时,再经水耙3遍处理,能达到新增水田建设的防渗标准;与压实度达到88%的防渗层相比,可避免不必要的施工投入,实现成本优化。此外,在试验地通过添加碳酸氢铵、防渗漏剂来降低田间水分渗透速率的方式,在降低投资成本的同时,基本上能够满足新增水田建设的防渗要求。可为其他地区新增水田建设的田间防渗提供借鉴与参考。Field anti-seepage measures are crucial to construction quality and cost of newly reclaimed paddy fields.To explore suitable field anti-seepage measures and save investment,a typical plot was selected as an experimental site in project area of Taiji Town,Funan County,Fuyang City,Anhui Province.Various measures were applied to this site,including mechanical compaction,addition of am-monium bicarbonate or anti-seepage agents for treatment,followed by comparative studies on water retention.Experimental results showed that mechanical compaction could effectively reduce water infiltration rate.When compaction degree reached 81%,followed by three times of water harrowing treatment,it could meet anti-seepage standard for newly reclaimed paddy fields.Compared with anti-seepage layer with 88%compaction,this treatment could avoid unnecessary construction inputs and optimize costs.Additionally,meth-od of reducing field water infiltration rates by adding ammonium bicarbonate or anti-seepage agents could largely meet anti-seepage re-quirements of newly reclaimed paddy fields while significantly reducing investment costs.It could provide reference and guidance for field anti-seepage measures in construction of new paddy fields in other regions.
