土壤改良剂对镉污染稻田的治理稳定性研究OA
Study on the Stability of Soil Amendments in the Treatment of Cadmium-contaminated Rice Fields
为验证大田环境下土壤改良剂对镉污染稻田的治理效果稳定性,开展了连续3 年的原位钝化试验.结果表明,土壤改良剂施用第1年,土壤酸化情况明显改善,土壤pH由5.64最高提升至7.13;土壤中有效镉含量与土壤pH呈显著负相关;稻米镉含量与土壤有效镉含量呈显著正相关,最高降幅达71.48%,治理效果整体随施用量的增加而增强.后续2年,处理组土壤pH、土壤有效镉含量均有所回弹,但稻米镉含量仍显著低于空白对照且降幅与施用量间无明显相关性,此外,所有处理组均未…查看全部>>
To verify the stability of the treatment effect of soil amendment on cadmium-contaminated paddy field under field environment,this study carried out in situ passivation test for three consecutive years.The results showed that soil acidification was significantly improved in the year of soil amendment application,and the soil pH was increased from 5.64 to 7.13;the effective cadmium content in the soil showed a signifi-cant negative correlation with the …查看全部>>
