Abstract

Abstract:

To investigate the impacts of agrivoltaic systems on desert soil environment， this study analyzed soil attribute variations in a 5-year operational tracking high-stilt photovoltaic array + jujube system in the Kubuqi Desert， comparing drip-irrigated， non-irrigated， and non-photovoltaic control areas. The results showed that drip irrigation alleviated soil moisture deficits caused by jujube cultivation under non-irrigated conditions， restoring soil moisture to levels comparable to those of the control. Soils in photovoltaic areas exhibited significant increases in electrical conductivity （+11.8% in the drip-irrigated zone） and declines in calcium carbonate， total phosphorus （except the drip-irrigated zone）， available phosphorus， and available potassium. However， no significant differences in chemical indicators were observed between the drip-irrigated and non-irrigated treatments. Additionally， soil enzyme activities in photovoltaic areas were significantly higher than those in the control， with β-glucosidase and leucine aminopeptidase activities notably elevated in the drip-irrigated zone compared to the non-irrigated zone. Mantel tests revealed that changes in soil enzyme activity were co-regulated by electrical conductivity， available potassium， and available phosphorus. Pearson analysis further confirmed negative correlations between electrical conductivity and organic carbon/calcium carbonate， whereas positive correlations existed between available phosphorus/potassium and soil moisture. Therefore， drip irrigation facilitates crop growth in desert agrivoltaic systems by enhancing the chemical and biological transformation of mineral nutrients， thereby establishing bioactive microzones.
