秸秆还田对盐碱稻田土壤Zn、Cd、Pb消减与As积累的特异性及产量的影响
Effect of Straw Incorporation on the Specificity of Zn,Cd,and Pb Reduction and As Accumulation in Saline-Alkali Paddy Soil and Rice Yield
摘要
Abstract
Through field location experiments,the effect of straw incorporation on soil heavy metals and rice yield in saline-alkali paddy fields in the western part of the Songnen Plain was explored.The results indicated that straw incorporation exhibited significant element-specific regulation of soil heavy metals.It markedly reduced soil Zn,Cd and Pb content,while markedly increasing As content.The As content exhibited a non-linear increase with the rise in straw incorporation rate,with increases of 3.81%-6.69%.Significant differences were observed among treatments S0,S1,and S2,whereas no significant differences existed among treatments S2,S3,and S4,suggesting a saturation threshold(50%)for As accumulation under straw incorporation.In addition,straw incorporation exhibited a yield threshold,with the maximum rice yield occurring at 100%straw incorporation and yield decreased beyond 150%straw incorporation.In conclusion,the appropriate straw incorporation rate was 100%for the saline-alkali paddy fields in the western part of the Songnen Plain.关键词
