向日葵对重金属胁迫的防御机制及其土壤修复效率提高途径
Defense Mechanism of Sunflower against Heavy Metal Stress and Ways to Improve Its Soil Remediation Efficiency
摘要
Abstract
Heavy metal contaminated soil is difficult to remedy because of its concealment,high residue,heavy metal is easy to accumulate in organisms through the food chain,posing a threat to human health.Sunflower (H.annuus) is an oil crop with high economic value,has high tolerance to heavy metals and strong enrichment capacity for heavy metals.This paper reviewed the accumulation and distribution characteristics of heavy metals in sunflower,the detoxification mechanism from the aspect of activating antioxidant systems,complexing heavy metal ions,ways of improving soil remediation efficiency from the aspect of agronomic practices,chelator-induced healing,microbial remediation,finally discussed the future study.关键词
