为掌握含盐量的季节变动情况,指导一般农业生产,进行了滨海盐土电导率、全盐量和氯离子含量关系式的推导。结果表明,土壤全盐量(St)和氯离子量(SCl-)的有效关系式为SCl-=0.7148St-0.7898;土壤氯离子含量(SCl-)和电导率(EC25)的有效关系式为SCl-=2.738EC25-1.2164;土壤全盐量(St)和电导率(EC25)的有效关系式为lgEC25=1.0426lgSt-0.5676。
In order to grasp the seasonal variation of salinity and guide the general agricultural production, the relationship between the conductivity of sea salt soil, total salinity and chloride ion content was deduced. The results showed that the effective relational equation between soil total salt (St) and chloride ion (SCl-) was SCl- = 0.7148St-0.7898. The effective relationship between soil chloride ion content (SCl-) and conductivity (EC25) SCl- = 2.738EC25-1.2164; the effective relationship between soil total salt (St) and conductivity (EC25) is lgEC25 = 1.0426lgSt-0.5676.
