通过室内盆栽试验,分析了施用氧化亚铁硫杆菌QBS-01和赤泥对水稻体内镉含量及分布规律的影响,探索利用氧化亚铁硫杆菌QBS-01及赤泥治理稻米Cd污染的可行性。结果表明,添加氧化亚铁硫杆菌QBS-01和赤泥后,水稻株高及产量增加,根、茎、叶、谷壳和糙米中Cd含量显著降低,Cd含量降低幅度由高到低依次为赤泥+氧化亚铁硫杆菌QBS-01配施处理>赤泥单施处理>氧化亚铁硫杆菌QBS-01单施处理,降低幅度最大的处理为R2T2。单施赤泥时,随着添加量增加,稻米Cd含量先降低后升高;氧化亚铁硫杆菌QBS-01单施及其与赤泥配施时,随着添加量增加,稻米Cd含量无显著变化。虽然添加赤泥和氧化亚铁硫杆菌QBS-01能显著降低糙米C...

In order to find Thiobacillus ferrooxidans QBS-01 and red mud used to control cadmium pollution in rice grains, the effects of their addition amount and method of fertilizing on the cadmium contents in rice grains and transportation in rice were studied by pot experiment. The results showed that the plant height and yield of rice increased after T. ferrooxidans QBS-01 and red mud added, while the cadmium contents in root, stem, leaves, chaff and brown rice decreased significantly. Reduction degree of cadmium contents in root, stem, leaves, chaff and brown rice were in order combined applicatio...
