Shuitu Baochi Xuebao, 2001 根据灌区盐量平衡原理，采用实际监测资料，对渭干河及其所属的库车、沙雅、新和县平原绿洲灌区进行盐均衡分析，深入探讨了临界灌排比的影响因素及其确定方法。研究结果表明：（1）灌排比的概念简捷明了，体现了干旱区水利建设、灌溉农业的特点，可作为衡量干旱区绿洲灌区水盐运动状态的一个指标，同时亦是进行灌排管理、规划设计的科学依据。（2）临界灌排比与灌溉引水量、排水量、河水含盐浓度、排水含盐浓度等因素有关。胃干、库车、沙雅、新和灌区监界灌排比分别为10．80，6．55，20．09，21．48。若没有特殊的地形地貌 ...

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 ...
