salt content of soil的意思|示意

It is found by indoor experiments that the thermal conductivity of saline soil has very close relation with salt component (salts) and salt content.

室内试验表明，含盐土的导热系数与其含盐成分(盐类)及含量有很大的关系。

Saline soil with salt content greater than 0.3% is widely distributed and accounts for 77.7% of the total irrigated area.

灌区盐碱土以全盐量大于0.3％的中度以上盐碱土分布较广，占灌区面积的77.7％。

The threat of soil salination to agriculture has been become an important problem affecting the whole world, while sodium is a major type of salts resulting to higher salt content of soil.

土壤盐渍化对农业的威胁是一个全球性的问题，而钠盐是造成盐分过高的主要盐类。

The salt content, salt composition and thickness of concentrated salt in the top layer of soil are main factors that should be taken into account in soil salinity classification.

表层土壤含盐量，以及盐分组成和积盐厚度等是研究土壤盐渍化程度分级应考虑的主要因素。

The average soil salt content of desalt region cut down as the cumulative infiltration volume rose and went up with the water concentration and initial water content.

脱盐区土壤平均含盐量随累积入渗量的增加而减少，随入渗水矿化度和土壤初始含水量的增加而增加。

Based on two-year field experimental measurements in a typical area and a soil salt balance model, the average soil salt content changes of 1.2 m depth were simulated and validated.
