农田土壤重金属污染的农业生态修复技术

Agro-ecological Remediation Technologies on Heavy Metal Contamination in Cropland Soils

总结了常见的农田土壤重金属污染的农业生态修复技术,包括合理施用化肥、施用生物有机肥、秸秆还田、调整作物种植结构、筛选重金属低积累作物品种和耐性作物品种、深耕深翻、控制土壤水分以及施用石灰等修复措施,并对农田土壤重金属污染修复技术的前景进行了展望。

This article summarized the common agro-ecological remediation technology of heavy metal contamination in cropland soils, in- cluding the rational application of fertilizer, bio-organic fertilizer use, straw application, adjusting the crop planting structure, screening lowly-enriched heavy metal crop varieties and tolerant varieties, super-deep plow, soil moisture control, lime application and so on. The out- look of the remediation technology of heavy metal contamination in cropland soils was prospected.
