摘要
为探讨硅肥对农田土壤Cd污染的修复效果,在田间试验条件下,研究了不同硅肥处理对Cd轻度污染农田水稻的修复效果。结果表明:不同硅肥处理可以降低Cd轻度污染农田中水稻糙米Cd含量,降幅为2.02%~16.00%,提高土壤pH值0.36~0.45,降低土壤有效态Cd含量,降幅为34.88%~45.47%,水稻产量增加3.63%~6.23%,基施与叶面喷施联合施用硅肥对农田土壤Cd污染的修复效果最好。
In order to explore the remediation effect of silicon fertilizer on Cd polluted farmland,a field experiment was conducted with different silicon fertilizer treatments on Cd slightly polluted paddy field.The results showed that different silicon fertilizer treatments could reduce Cd content in brown rice by 2.02%~16.00%,the pH value of soil increased by 0.36~0.45,the available Cd content decreased by 34.88%~45.47%,and the yield of rice increased by 3.63%~6.23%.Applying silicon fertilizers in combination of basal application and foliar spraying had the best remediation effect on Cd polluted farmland.
