soil salt content

基本解釋

Determining soil electromagnetic induction conductivity (EM) in situ with EM38 is a new and convenient method for rapid determination of soil salt content.
利用EM38型電磁感應電導儀（EM38）在野外原位測定土壤電磁感應電導率（EM），是一種快速簡便測定土壤含鹽量的新方法。
In compared with irrigation with saltish water all, irrigation with saltish and fresh alternatively can decrease soil salt content and increase cotton yield.
採用鹹淡水交替灌溉可以降低土壤含鹽量，增加棉花産量（與完全用微鹹水灌溉相比）。
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.
脫鹽區(qū)土壤平均含鹽量隨累積入滲量的增加而減少，隨入滲水鑛化度和土壤初始含水量的增加而增加。

土壤鹽分
The study focuses on the soil. When the soil salt content changes, it is difficult to distinguish that is resulted from shelterbelt or other factors.
灌區(qū)的土壤和潛水是開放系統(tǒng),針對土壤進行研究,儅土壤鹽分濃度發(fā)生變化時,難以區(qū)分哪些由防護林影響所致,哪些是其它因素所造成。
