摘　　要：在田间试验条件下,以江苏诺丽慧农农业科技有限公司提供的两种生物炭掺混肥为研究对象,采用电感耦合等离子体质谱仪(ICP-MS),对施用生物炭掺混肥的稻田土壤及其水稻籽粒中重金属镉(Cd)和砷(As)含量进行了测定,研究了生物炭掺混肥中化肥减施对水稻产量与结构的影响.结果表明:与对照常规复合肥相比,两种生物炭掺混肥处理对水稻籽粒中重金属Cd的富集系数分别降低20.49%和45.23%,As的富集系数降低57.58%和63.63%;两种掺混肥处理的水稻产量与对照处理相比产量增加4.17%和8.68%.生物炭掺混肥不仅控制了水稻籽粒重金属Cd和As的积累,而且可以提高水稻产量,在控制农田生态环境污染和化学肥料的减施增效上具有推广应用价值.Under the condition of field experiment,the bulk-blended biochars fertilizers from Jiangsu factory supply agricultural development Co.Ltd were employed to investigate the yield-improving effect and immobilization of cadmium(Cd)and arsenic(As)in farm land soil with bulk-blended biochar fertilizers.The results showed that the enrichment coefficient of Cd in rice grain was decreased by 20.49% and 45.23% respectively compared with the control after-applying two bulk-blended biochar fertilizers.And-the-enrichment coefficient-of-As-was decreased by 57.58% and 63.63% compared with the control.Significantly,the rice yield treated with two formulations was 4.17% and 8.68% higher than that of conventional compound fertilizer treatment.Compared with conventional compound fertilizer,bulk-blended biochar fertilizers not only controls the accumulation of heavy metals Cd and As,but also can improve the yield of rice,and has obvious advantages in controlling farmland ecological environment pollution and chemical fertilizers.
