英文摘要	In this work, an acid soil remediation agent (ASRA) was developed based on a nano composite composed of anhydrous sodium carbonate (ASC), attapulgite (ATP), and straw ash-based biochar and biosilica (BCS), wherein ASC was supported by ATP, and the resulting ASC-ATP was loaded into the micro/nano pores of BCS. ASRA with a porous nanonetworks structure could efficiently inhibit the loss of Ca2+ and increase the pH of the acid soil. Meanwhile, it was shown that the ASRA was effective on acid soil in both lateral and vertical directions. Additionally, because of the pH improvement and the adsorption capacity, ASRA could significantly decrease the migration and contamination of hexavalent chromium (Cr(VI)). Additionally, the pot experiment proved that ASRA could effectively reduce the uptake of Cr(VI) by corn, and exhibit a positive effect on the height, chlorophyll content in the leaves and the root length of corn. Therefore, this work may provide a fundamental and facile method on the remediation of Cr(VI)-contaminated acid soil.
