摘要

镉是一种常见的环境重金属,对人类和其他动植物具有很强的毒性和致癌性。因此,本研究旨在评估蛭石堆肥对萝卜(Raphanus sativus)根从土壤中吸收镉的可行性。为了进行这项研究,我们对土壤中镉浓度为 0、50000 和 100000 微克/升的蛭石堆肥的四种不同比例进行了评估,分别为 1:1、1:4、2:4 和 3:4。使用原子吸收光谱(AAS)测量了样品中的镉含量。结果表明,每种土壤的肥料比例为 3:4 时,植物对镉的吸收量最小。此外,结果还显示,在肥料与土壤用量比例最大(3:4)的情况下,油菜根系的生长率最高。这项研究表明,蛭石堆肥作为一种有机肥料,具有很好的吸附土壤中金属镉的能力。在土壤中添加有机肥料可增加土壤对重金属(镉)的吸收,防止其进入食物链。

Data on vermicompost effect on the uptake of cadmium from soil by the roots of radish (Raphanus sativus)

Cadmium is a common environmental heavy metal that is very toxic and carcinogenic for human and other flora and fauna. Therefore, this study is aimed to evaluate the fisibility of vermicompost fertilizer for cadmium uptake from soil by the root of radish (Raphanus sativus). For the purpose of the study, four different ratios of one case control, 1 per 1, 1 per 4, 2 per 4, 3 per 4 vermicompost fertilizer per soil with 0, 50000 and 100000 µg/L cadmium concentrations was evaluated. Cadmium in the samples was measured using an Atomic Absorption Spectroscopy (AAS). The results showed that the minimum uptake of cadmium by the plant was observed for 3 per 4 ratio of fertilizer per soil. In addition, results revealed that highest growth rate of Raphanus sativus roots occurred in maximum ratio of fertilizer per soil usage (3 per 4). This study showed that vermicompost as a organic fertilizer has a good ability to adsorb cadmium metal from soil. Therfore, vermicompost application can be considered as an inexpensive natural adsorbent in arable land contaminated with cadmium.

  • Heavy metals are very toxic and carcinogenic to human and animals.

  • Adding organic fertilizer to the soil increases the absorption of heavy metal (cadmium) in the soil and prevents it from entering the food chain.

  • The relationship between the concentration of cadmium absorbed by the tuber of radish plant and the percentage of vermicompost added to the soil is presented.
