摘　　要：解厌氧混合菌群、红麻种植及红麻骨炭粉对镉污染土壤修复的影响,本研究采用洒菌后盆栽薄膜覆盖封闭、盆栽无薄膜覆盖封闭及大田无薄膜覆盖封闭进行处理,通过对盆栽水稻收割后的株高等10个性状进行考种调查及对三套方案各处理的水稻糙米重金属Cd含量进行检测,并检测各处理在洒菌时(前期)收割时(后期)土壤Cd化学形态。结果表明:无薄膜封闭处理比有薄膜封闭处理后的农艺性状较好,性状大小顺序为HYT>HY>Y>CK,干谷产量与对照相比,HYT的产量增加49.65%,HY增加35.45%,Y的产量增加21.24%;各处理对谷子糙米Cd含量降低具有一定作用,糙米Cd含量高低顺序均为HYT<HY<Y<CK,与对照CK处理相比,其中盆栽无薄膜封闭的HYT处理降低了93.13%,HY处理降低了83.26%,大田无薄膜封闭的HYT处理降低了63.36%,HY处理降低了34.91%;三套试验的各处理对土壤重金属Cd都具有一定的降低转移能力,有薄膜封闭处理为Y降低转移能力最强,其次是HYT。盆栽无薄膜封闭处理和大田无薄膜封闭处理均为HYT降低转移能力最强,HY次之。各处理土壤镉金属形态中的可利用形态均降低,并且不可利用形态增加,从而降低植物对其的吸收。盆栽无薄膜封闭处理和大田无薄膜封闭处理的变化趋势相似。In order to understand the effects of anaerobic mixed flora,kenaf planting and kenaf bone charcoal powder on the remediation of cadmium-contaminated soil.this study adopted the treatment of potting film covering,potting without film covering and field without film covering.The plant height 10 characters of potted rice after harvest were investigated and the heavy metal Cd content of brown rice treated by three schemes was detected.The chemical morphology of soil Cd was also detected in each treatment at the time of spreading bacteria(early stage)and harvesting(late stage).The results showed that the agronomic characters without film sealing were better than those with film sealing,and the order of characters was HYT>HY>Y>CK;compared with CK,the dry grain yield of HYT,HY and Y increased by 49.65%,35.45%and 21.24%respectively.All treatments had certain effect on the reduction of Cd content in brown rice.The order of Cd content in brown rice was HYT<HY<Y<CK;compared with CK treatment,HYT treatment without film closure in pot decreased by 93.13%and HY treatment by 83.26%,HYT treatment without film closure in field decreased by 63.36%and HY treatment by 34.91%.All the treatmentsin the three sets of tests had certain ability to reduce the transfer of heavy metal Cd in soil.The treatment with film closure had the strongest ability to reduce the transfer of heavy metal Cd in soil,followed by HYT.HYT and HY showed the highest decreasing ability of metastasis in both potted and field treatments.The available form of cadmium metal in soil of all treatments decreased,and the unusable form increased,thus reducing the absorption of cadmium by plants,The trend of change was similar between potted closed treatment and field closed treatment without film.
