| 摘 要： | 通过室内土柱试验探讨了不同矿化度水淋洗重度盐碱土的水盐运移特征。结果表明,微咸水和咸水的入渗速率要明显高于淡水入渗。在灌水淋洗后土壤盐分含量均大幅下降,以淡水和微咸水的脱盐效果较好。3个处理淋洗后土壤的Na^＋、Cl^-、SO4^2-、K^＋、Mg^2＋、Ca^2＋含量下降,CO3^2-、HCO3^-含量有所上升,土壤...

| Abstract: | An indoor soil column experiment was carried out to investigate the water and salt transporting characteristics of severe saline-alkali soil,which was leached with different salinity of water.The results indicated that the soil infiltration rate of mincro-saline and saline water was obviously higher than that of fresh water.The soil salinity desended significantly after irrigation and the soil desalinization effect by leaching with fresh and mincro-saline water was better.After irrigation,soil pH and the co... |
