Shuitu Baochi Xuebao, 2007 基于土柱实验，对有作物生长条件下的污水灌溉土地处理慢渗系统氮素去除和作物生长状况开展实验研究，探讨在灌溉原污水中添加有机碳对该系统去除氮素和作物生长状况产生的影响作用。实验研究结果表明，随着灌溉原污水中有机碳含量的逐渐增加，污水灌溉土地处理慢渗系统下排的水量有所增大，排水中的氮素（铵态氮、硝态氮、总氮）淋溶量和化学需氧量有所增加，而作物的干物质量和吸氮量则明显下降；增加灌溉原污水中的有机碳含量，会影响污水灌溉土地处理慢渗系统去除氮素的效果和作物生长条件，在增加基于硝化和反硝化作用的除氮量同时 ...

Shuitu Baochi Xuebao[目的] 微咸水灌溉是缓解农业用水紧张、保障粮食生产的重要途径之一,但灌溉水中的可溶性盐会导致土壤盐分累积,进而影响作物生长,寻求适宜的灌溉水盐分浓度是咸水、微咸水资源得到安全利用的有利保障。[方法] 研究采用遮雨盆栽试验种植冬小麦,以去离子水为对照(CK),添加氯化盐形成不同浓度的微咸水处理,灌溉水电导率(ECw)分别为:0.26(CK),3.00(S1),5.26(S2),7.07(S3),9.24(S4) dS/m,研究土壤水盐分布和冬小麦生长、光合生理及产量形成的响应。[结果 ...

Shuitu Baochi Xuebao, 2004 对在海侵灾害最严重的莱州湾地区，在油葵生育期内利用不同浓度的海水直接灌溉两次，研究0～40cm土层土壤盐分及Na^ 、CI^-、Ca^2 、Mg^2 、K^ 含量的分布、迁移规律，为确定合适的灌溉定额和灌溉次数提供最基础的技术参数。结果表明：①60％以上浓度海水灌溉，5～40cm土层土壤盐分呈积累趋势，次生盐渍化明显；40％海水灌溉后轻微积盐．若无充沛的雨水淋洗，则须结合一定的农业措施以防造成次生盐害；20％海水浓度在灌溉定额为800m^3／hm^2时能保持土壤盐分的盈亏平衡。②Na^ 和CI ...
