韶关地区土壤-水稻体系铬含量研究及其相关性分析

Analysis on Chromium Contents of Soil-rice System and Their Correlation in Shaoguan

对韶关地区土壤及其水稻不同部位的铬含量进行了采样测定,分析了水稻中重金属Cr含量与土壤Cr含量的关系。结果表明:水稻不同部位的铬含量不同,其根、茎、叶及米粒中的铬含量顺序为根(茎(叶(米粒,且与土壤中的铬含量呈正相关。说明水稻中的Cr含量与其生长环境密切相关,水稻对金属铬具有一定的富集性。研究结果可为土壤的使用、修复处理及水稻生长机制研究提供借鉴。

The chromium contents in soil and different parts of rice in Shaoguan were determined.The relationship between the chromium contents in rice and soil was analyzed.The results showed that the chromium contents in different parts of rice were different,the content in the order was rootstemleafrice kernels,which was positively correlated with that in soil.That is,the chromium content in rice was closely related to the growth environment,and rice could enrich chromium.The results would provide the references for the soil use and remediation,and the growth mechanism of rice.
