1) sodium saline soil
苏打盐渍化土壤
1.
The factors that determine conductivity of sodium saline soil are analyzed.
分析了盐渍化土壤导电性的决定因子 ,提出松嫩平原苏打盐渍化土壤的电导率主要由土壤溶液中Na+和HCO-3 离子的总电荷数和迁移速率决定 ;而土壤中粘土矿的含量会因外在环境条件 (土壤含水率 )的变化而影响土壤的电导率 ,其是针对不同的土壤物理特征对测量仪器进行校正的理论依据。

本文通过在"中国大安碱地生态试验站"进行野外定位实验,研究了人工控制潜水位下的土壤水盐动态,进一步探讨了不同潜水位下的苏打盐渍土水盐运移规律。
2.
An experiment of leaching saline-sodic soil with brackish water was conducted for analysis of changes in physical and chemical properties of the soil,such as soil infiltration,bulk density,salt and alkali content,etc.
在轻度盐碱化和中度盐碱化2种苏打盐渍土上,分别设置对照、补充灌溉、低额淋洗和高额淋洗4个处理,对经微咸水淋洗的苏打盐渍土的土壤渗透性、土壤容重以及土壤盐碱含量的分析结果表明,在高额淋洗区,微咸水在中度苏打盐渍土中渗透速率约为对照区的3倍,在轻度苏打盐渍土中约为对照区的2倍。
4) sodic saline soil
苏打盐渍土
1.
Variation of water and salinity in sodic saline soil during frozen-thawing season;
冻融季节苏打盐渍土的水盐变化规律
2.
Water transportation between soil-groundwater in sodic saline soil system;
通过野外定位观测和室内分析,探讨了苏打盐渍土微域特征(32m长的横截面)及其水分和地下水之间的转化规律。
5) Soda-saline soil
苏打盐渍土
1.
The regulation of dynamic change of soda-saline soil has a close relation with climate and the seasoning process of soil freezing and thawing Soil freezing and thawing will accelerate the process alkalization for the soda-saline soil The topographic changes in small area and the human activity will directly control the direction and the speed of water-soluble salts of soil.
苏达盐渍土动态变化规律与气候和土壤季节性冻融过程密切相关,土壤融冻加速苏达盐渍土碱化作用,而微地形变化及人为活动直接控制土壤水溶性盐类运动方向和速度,所有这些严重影响着作物的生育,本文着重阐述耕地土壤融冻过程和微地形对苏打盐渍土水盐运动的影响及改良措施。
6) soda-type saline soil
苏打渍盐土
1.

补充资料：土壤次生盐渍化
分子式：
CAS号：
性质：又称土壤次生盐渍化。原来非盐碱化的土壤由于不合理的灌溉或积涝而使土壤盐碱化的过程。不合理灌溉包括大水漫灌使地下水位升高，灌溉水含盐量较高，有灌无排，积涝即土壤长期被水浸泡，水不能排出，使地下水位升高。
