Abstract:

【Objective】 To determine the enrichment and distribution of five heavy metals in melon plants. 【Methods】 From June 26 to July 25, ICP-MS was used to determine Cu, Cd, As, Cd, Cr and Ni analyzed the distribution of five heavy metals in different growth stages. Furthermore, through the percentage of the enrichment coefficient of five heavy metals in each plant, the change and the correlation of five heavy metals in melon plants were explored.【Results】 From June 26 to July 25, The enrichment assignments of Cr, Ni and As were distributed by root> leaf> stem> stem> fruit; In contrast, the enrichment of Cu from 26 June to 25 and Cd from 26 June to July 16 was assigned leaf> root> stem> fruit; with the extension of time, the proportion of Cr, As, and Cd increased first and then decreased and the proportion of Ni and Cu showed a downwards trend. When the enrichment allocation of fruit Cr, As, Cu and Ni increased, the enrichment allocation of these four heavy metals in the roots tended to decrease, while the enrichment allocation of Cr, As and Ni in the leaves increased. Meanwhile, there was a decreasing trend in the Cd and Cu. 【Conclusion】 The above results show that the distribution, enrichment proportion of the five kinds of heavy metals in melon plants and the related sites is different according to the different types of heavy metals.

摘要:

【目的】研究甜瓜不同生长阶段5种重金属在植株中富集分配的变化及其关联性。【方法】于2020年6月26日至7月25日,每间隔4 d分别采集甜瓜根、茎、叶、果实及对应根际土壤样品,采用电感耦合等离子体质谱法(ICP-MS)测定样品中铜Cu、镉Cd、砷As、铬Cr和镍Ni 5种重金属含量,定量分析植株各部位5种重金属富集系数所占百分比,研究不同生长阶段5种重金属在甜瓜植株中富集分布及其关联性。【结果】6月26日至7月25日,甜瓜植株Cr、Ni、As的富集分配为根>叶>茎>果实;6月26日至7月25日Cu与6月26日至7月16日Cd的富集分配为叶>根>茎>果实;7月16日至7月25日,甜瓜植株Cd富集分配为根>茎>叶>果实;随时间延长,甜瓜果实中Cr、As、Cd富集系数所占比例整体呈先升高后降低的趋势,Ni和Cu富集系数所占比例整体呈降低趋势;当甜瓜果实Cr、As、Cu、Ni富集分配增加时,植株根中该4种重金属的富集分配有降低趋势,叶中Cr、As、Ni的富集分配有升高趋势,Cd和Cu有降低趋势。【结论】5种重金属在甜瓜植株中的分配、富集占比变化、关联部位因重金属种类的不同而有所差异。
