Abstract：Accurate determination of trace silicon content in fruits and vegetables is crucial for guiding agricultural production,however,conventional silicon determination methods suffer from technical limitations including complex pretreatment procedures and severe matrix interference.In this study,a method for determining trace silicon content in agricultural products was established by using microwave digestion pretreatment combined with ICP-MS.The study explored the enrichment patterns of silicon element in strawberry cultivation and investigated the effects of different fertilization concentrations and periods on silicon absorption in strawberries.The results showed that the method for silicon determination in agricultural products had a good linear relationship,with a detection limit of 0.013 0 μg/mL,precision,accuracy and recovery that met experimental requirements.The study on the enrichment law of silicon element in strawberry cultivation revealed that both fertilization concentration and timing significantly affected silicon absorption in strawberries.With the increase in fertilization concentration,the accumulation of silicon in strawberries was higher,and fertilization during the flowering period was more beneficial for silicon accumulation than during the seedling period.This research provided reliable technical support for the quantitative analysis of silicon elements in fruits and vegetables,and offered theoretical basis and technical guidance for silicon fertilizer application in strawberry cultivation.
