Abstract:
Taking the Meixian—Zhouzhi region, a vital kiwifruit production area of northern foothills of the Qinling Mountains, as the study area, this research conducted a systematic investigation of soil elements in kiwifruit orchards and their corresponding concentrations in kiwifruit fruits.The study aimed to elucidate the relationship between soil elements and fruit quality, while evaluating the enrichment capacity for beneficial elements and restriction capability for harmful elements in kiwifruit.Results demonstrated significant positive correlations between beneficial soil elements(Se, Fe, K) and their corresponding concentrations in fruits.Kiwifruit exhibited notably higher enrichment coefficients for nutritional elements(Se, Fe, K) co
mPAred to harmful elements, particularly showing extremely low accumulation coefficients(below 0.05) for heavy metal elements(Cd, Hg, As).This indicates kiwifruit′s active absorption mechanism for beneficial elements while effectively restricting harmful element accumulation in fruits.Significant correlations were identified between major volatile components in kiwifruit and elemental contents in both fruits and soil, with elements including Se, Fe, K and Mg demonstrating positive effects on fruit quality.These findings provide scientific insights for optimizing cultivation practices to enhance kiwifruit quality and promote high-quality development of the kiwifruit industry.
