白星花金龟虫粪对铬、砷污染土壤-樱桃萝卜系统的修复效应
Remediation Effects of Protaetia brevitarsis Frass on Chromium-Arsenic Contaminated Soil-Cherry Radish System
摘要
Abstract
To systematically evaluate the passivation and remediation efficiency,as well as the improvement of physicochemical properties and plant physiological metabolism of Cr and As contaminated soil in mine tailings ponds by the P.brevitarsis larvae frass sand,a greenhouse pot cultivation method was used.Cherry radish was selected as the test crop,and seven treatment levels were set up[insect feces sand was added at 0%(CK),10%(T1),20%(T2),40%(T3),50%(TN),80%(T4),and 100%(T5)of soil weight]to study its effects on soil physicochemical properties,soil Cr and As content,and soil enzyme activity.At the same time,its effect on photosynthetic indicators,heavy metal content in edible parts,and plant enzyme activity of cherry radish were analyzed.The results showed that with the increase of application rate of P.brevitarsis larvae frass sand,soil pH value,heavy metals Cr and As content showed a decreasing trend,while conductivity,organic matter content,available nitrogen content,available phosphorus content,soil urease activity,invertase activity,and catalase activity significantly increased(P<0.05).Cherry radish showed reduced absorption of Cr and As,improved photosynthetic indicators(relative chlorophyll content,leaf nitrogen content),and increased antioxidant enzyme(superoxide dismutase,peroxidase,catalase)activity.The redundancy analysis results showed that soil organic matter content was the core driving factor(with a contribution rate of 83.0%),indicating its central role in soil fertility.In summary,the P.brevitarsis larvae frass sand could enhance the adsorption capacity of soil heavy metals(Cr,As)by regulating soil physical and chemical properties,improving soil fertility and soil enzyme activity,and could effectively reduce the bioavailability of heavy metals,alleviating the toxicity to cherry radishes.Among them,adding insect feces sand at 80%of soil weight(T4 treatment)has a better effect on soil remediation and plant safety production.关键词
