中文摘要	通过开展室外土柱模拟淋洗试验,选择间歇淋洗与连续淋洗两种淋洗模式,分析不同灌水总量和不同灌水频次相互组合条件下盐渍土的改良效果。结果表明:(1)灌水量相同情况下,间歇淋洗滤出液的电导率高于连续淋洗,间歇淋洗的淋洗效果好于连续淋洗;(2)灌水量不同条件下,滤出液体积随灌水量的增加而增多,灌水量越大盐分淋洗效果越好;(3)淋洗结束后,土壤pH值较淋洗前均有下降,与土壤盐分有相同的变化趋势;灌水量越大,脱碱效果越好。在本试验条件下,盐分淋洗效果以15L分3次给水的间歇淋洗方式最优,淋洗效率为11.58g/L,土壤pH值均由8.42下降到8.07。可供制定维持农田水盐平衡的节水灌溉制度以及盐碱地改良参考。
英文摘要	The author made a simulated leaching soil columns experiment in outdoors,including intermittent leaching and continuous leaching,the purpose was to analyze the improvement effect of saline soil under the combination of different irrigation amount and different irrigation frequency.The results indicated:(1)Under the same irrigation amount,the percolate electric conductivity of intermittent leaching higher than continuous leaching,leaching efficiency of intermittent leaching was higher than continuous leaching from beginning to end.(2)Under the different irrigation amount,the percolate volume of amplified along with the irrigation amount growth,the greater irrigation amount,the better leaching efficiency.(3)The change trend of soil pH value was drop than before after leaching,and it was same of the change trend of soil salt;the greater irrigation amount was,the better the efficiency of alkali removes.In this experiment,leaching efficiency of 15Lpoints three times is optimal,leaching efficiency was 11.58g/L,15L of the surface soil pH values decreased from 8.42 to 8.07.The results can provide reference for the improvement of saline alkali land in arid area and the establishment of water saving irrigation system of maintaing farmland water and salt balance.
