摘  要：
为寻求防治设施土壤次生盐渍化的最优暗管布局方案,设计不同暗管埋设排水处理(CK:不埋设暗管,T1:埋深0.6m、间距4m,T2:埋深0.8m、间距4m,T3:埋深0.6m、间距6m,T4:埋深0.8m、间距6m),研究不同暗管埋设排水处理对土壤化学性质、番茄产量及品质的影响;同时引入投影寻踪分类模型,对不同暗管埋设排水处理的综合效益进行分析和评价。结果表明:暗管排水处理对土壤化学性质影响显著,耕层土壤电导率(EC)和有机质、速效养分含量均呈下降趋势,其中T1处理下降幅度最大;T2和T3处理番茄产量处于较高水平,分别为142.58t/hm2和137.99t/hm2,两者差异不显著;T4处理番茄的综合品质最优,T2相对较差,而T3和T1差别不大;T3处理综合效益最优,投影值达到1.747 5,T4次之,T2最差,投影值仅为0.251 8。综上,暗管埋深0.6m、间距6m可用作设施农田最优的暗管布局方案。

摘  要：
To explore the best arrangement scheme of subsurface drainage pipes,different drainage treatments were designed(CK:no drainage pipes;T1:0.6mdepth and 4mspace;T2:0.8mdepth and 4mspace;T3:0.6mdepth and 6mspace;T4:0.8mdepth and 6mspace),and the effects of subsurface drainage systems on soil chemical properties,tomato quality and yield were studied;meanwhile,the projection pursuit model was introduced to evaluate the comprehensive benefits of different treatments.The results showed that subsurface drainage had significant effects on soil quality,the surface soil EC,organic matter and available nutrients content presented a decline trend,especially T1treatment;tomato yields of T2 and T3treatment were higher,and there was no difference between them,the yields were 142.58t/ha and 137.99t/ha,respectively;tomato comprehensive quality of T4 treatment was best,T2 treatment was the poorest,and there was no significant difference between T1 and T3treatment;comprehensive benefit of T3 treatment was the highest,projection value of which reached 1.747 5,followed by T4 treatment,and T2 treatment was the poorest with projection value of 0.251 8.Therefore,0.6mdepth combined with 6m space could be recommended as the optimal arrangement scheme of subsurface drainage pipes.
