以贵州中部地区近年主栽的10个水稻品种为试验材料，在中轻度重金属复合污染农田土壤上开展田间原位小区试验，探究不同水稻品种对镉（Cd）、铬（Cr）、铅（Pb）、镍（Ni）、铜（Cu）和锌（Zn）的吸收累积能力差异，并筛选出适宜贵州中部青黄泥田种植的重金属低累积水稻品种。结果表明，不同水稻品种根区土壤重金属含量存在一定的田间异质性，且同一品种的重复之间也具有一定的田间异质性；不同水稻品种糙米对不同重金属元素累积具有显著性差异，参试水稻品种糙米对重金属的富集能力强弱整体表现为Zn>Cd>Cr>Cu>Ni>Pb。水稻品种间对同一典型有害重金属元素的累积存在显著差异，按照糙米中重金属含量进行聚类分析，可以把水稻品种划分为较高值类、中间值类和较低值类3个类别。10个水稻品种糙米综合污染指数（P_Z）（0.94~3.34）介于无污染至重度污染之间，Cr为主要污染贡献者，其单项污染指数（P_i）在0.47~1.94之间。供试水稻品种产量在8 242.8~13 434.0 kg/hm²之间，平均产量为10 843.8 kg/hm²，极差相差较大，为47.9%。筛选出宜香优800为适宜该地种植的重金属低积累水稻品种。

A field in situ plot experiment was conducted on farmland soil with moderate to light heavy metal compound pollution to determine the heavy metal content of soil and rice brown rice. Combining the results of rice yield, cluster analysis, and Neiluomei comprehensive pollution index, the aim was to screen rice varieties with low accumulation of compound pollution, in order to explore the differences in the absorption and accumulation abilities of different rice varieties to cadmium (Cd), chromium (Cr), lead (Pb), nickel (Ni), copper (Cu), and zinc (Zn), and screen the rice varieties with low accumulation of heavy metals suitable for planting in the blue yellow mud fields in central Guizhou, using 10 rice varieties mainly planted in central Guizhou in recent years as experimental materials, The results showed that there was a certain field heterogeneity in the content of heavy metals in the root zone soil of different rice varieties, and there was also a certain field heterogeneity between repeats of the same variety. The accumulation of different heavy metal elements in brown rice of different varieties was significantly different, and the overall accumulation ability of heavy metal elements in brown rice of 10 rice varieties was Zn>Cd>Cr>Cu>Ni>Pb. There were significant differences in the accumulation of the same typical harmful heavy metal elements among rice varieties. According to the clustering analysis of heavy metal content in brown rice, rice varieties can be divided into three categories: higher value category, intermediate value category, and lower value category. The comprehensive pollution index (P_Z) of brown rice of 10 rice varieties ranges from 0.94 to 3.34, ranging from no pollution to severe pollution. Cr is the main contributing element to pollution, and its single pollution index (P_i) ranges from 0.47 to 1.94. The yield of the 10 tested rice varieties ranged from 8 242.8 to 13 434.0 kg/hm², with an average yield of 10 843.8 kg/hm², with a significant difference of 47.9%. According to the above research results, it is recommended that Xiangyou 800 be a suitable rice variety with low accumulation of heavy metals for planting in this area.
