| 摘 要： | 为研讨土壤调理剂对水稻吸收重金属的影响,探索适宜大田推广的耕地生产障碍修复治理方法,提高受污染耕地质量,实现“边生产,边修复”的目的。在贵州省麻江县开展不同土壤调理剂对水稻吸收重金属强度影响的试验,选用楚戈土壤调理剂、富力邦土壤调理剂、土沃宝土壤调理剂、改性天然矿物材料等4种土壤调理剂,采用空白作对照。试验检测结果为：土壤调理剂处理后,土壤pH值提升率达0.65%～12.03%,土壤中有效镉含量降低10.64%～14.83%,土壤重金属砷含量降低0.4～1.8mg/kg;稻谷中镉含量降低了7.80%～44.07%,硒含量增加为0.004～0.017mg/kg;对水稻产量影响不明显。试验说明在受污染的酸性耕地中施用碱性土壤调理剂,可以提高土壤pH值,降低土壤中重金属砷含量和重金属有效镉的含量,也能减少稻谷对重金属镉的吸收。

| Abstract: | In order to study the effect of soil conditioner on heavy metal absorption of rice, explore the remediation and management methods of cultivated land production obstacles suitable for field popularization, improve the quality of contaminated cultivated land, and realize the purpose of "production and restoration at the same time". An experiment was conducted to investigate the effects of different soil conditioners on the heavy metal absorption intensity of rice in Majiang County, Guizhou Province. Four soil conditioners, namely Chuge soil conditioner, Fulibang soil conditioner, Tuwubao soil conditioner and modified natural mineral materials, were selected as blank controls. The results showed that after treatment with soil conditioner, soil pH value increased by 0.65%~12.03%, available cadmium content decreased by 10.64%~14.83%, and heavy metal arsenic content decreased by 0.4~1.8mg/kg. Cadmium content in rice decreased by 7.80%~44.07%, and selenium content increased by 0.004~0.017mg/kg. The effect on rice yield was not obvious. The experiment showed that applying alkaline soil conditioner in polluted acid cultivated land could increase soil pH value, reduce the content of heavy metal arsenic and available heavy metal cadmium in soil, and also reduce the absorption of heavy metal cadmium by rice. |
