水稻种植对农田镉污染土壤修复效果的影响与机制研究

Study on the Effect and Mechanism of Rice Planting on the Remediation of Cadmium Contaminated Soil in Farmland

水稻种植在修复受镉污染的农田中发挥着巨大作用,本文对此进行了深入探索。虽然水稻植物具有吸收和积累镉的能力,有助于从土壤中去除镉,但人们担心水稻对镉的吸收可能会增加,并对土壤健康产生长期影响。水稻修复镉污染土壤的机制,包括水稻根系对镉的吸收、通过根际过程在土壤中转化镉化合物,以及影响土壤镉水平的微生物的相互作用。了解这些影响和机制,有助于我们制定可持续的战略,从而减轻农业生态系统中的镉污染并确保食品安全。

Rice cultivation plays a significant role in the restoration of cadmium contaminated farmland,and this article explores this in detail.Although rice plants have the ability to absorb and accumulate cadmium,which helps remove cadmium from the soil,people are concerned that rice’s absorption of cadmium may increase and have long-term effects on soil health.The mechanism of rice remediation of cadmium contaminated soil includes the absorption of cadmium by rice roots,the transformation of cadmium compounds in soil through rhizosphere processes,and microbial interactions that affect soil cadmium levels.Understanding these impacts and mechanisms can help develop sustainable strategies to reduce cadmium pollution in agricultural ecosystems and ensure food safety.
