摘要:

森美思(SAMMNS)是一种应用于“三废”污染治理的纳米多孔复合材料。为验证森美思纳米材料在稻田重金属Cd污染的治理效果,在土壤Cd、Cu复污染稻田开展了森美思纳米材料不同用量的正规田间试验。试验显示,施用化肥会使土壤酸化,使糙米Cd量降低和糙米Cu量上升。水稻对Cd具有很强的富集效应,对Cu只是一般吸收。结果表明,施用森美思纳米材料能显著提升土壤pH值,有效降低土壤有效Cd量和糙米Cd量,土壤有效Cd量与糙米Cd量之间存在正相关性。施用3000 kg/hm2森美思纳米材料糙米Cd量均值比空白对照和施肥对照分别下降40.54%和30.62%,处理差异达到显著水平。施用森美思纳米材料对降低糙米Cu量也有一定作用,但不及降低糙米Cd量效果。施用森美思纳米材料对水稻有小幅增产效果。

Abstract:

SAMMNS is a kind of nanometer material used in the treatment of “three wastes” pollution control. To verify the application effects of SAMMNS nanometer material on heavy metal Cd contaminated paddy fields, field experiments with different amounts of SAMMNS nanometer material were carried out in paddy fields with composite pollution by Cd and Cu. The experiments showed that the application of chemical fertilizers could acidify the soil, reduce the amount of Cd and increase the amount of Cu in brown rice. Rice had a strong enrichment effect on Cd, but only general absorption on Cu. The results showed that the application of SAMMNS nanometer material could significantly increase the pH value of soil and effectively reduce the effective Cd content in soil and that in brown rice, and there was a positive correlation between the effective Cd content in soil and that in brown rice. Compared with blank control and fertilization control, the mean value of Cd in brown rice with 3000 kg/hm2 SAMMNS nanometer material decreased by 40.54% and 30.62%, respectively, and the difference of the treatment reached a significant level. The application of SAMMNS nanometer material also had a certain effect on reducing the amount of Cu in brown rice, but it is not as effective as reducing the amount of Cd in brown rice. The application of SAMMNS nanometer material has a small yield increase effect on rice.
