施用沼渣对白菜及土壤重金属含量状况的影响
Effect of Contents of Heavy Metals by Application of Biogas Residue in Chinses Cabbage and Soil
摘要
Abstract
The main content of this article was to study the effects of heavy metals contents by application of biogas residue in Chinese cabbage and soil .It used Large-scale pig farm manure as raw materials and fermentation biogas residue as tested material .The results showed that:the biomass yield of the Chinese cabbage in condition of the traditional use level of biogas residue ,which was on the basis of the application of chemical fertilizer ,was signif-icantly higher than non-fertilizer and only chemical fertilizer treatment ,but it was lower than traditional the pig ma-nure treatment .Comparing with non-fertilizer and only chemical fertilizer treatments ,the application of biogas resi-due on the basis of chemical fertilizer could significantly increase the contents of Cd ,Cu,Zn in chinese cabbage ,re-duce the contents of Cr ,As in it;also,the contents of heavy metals ( Cd,Cu,Zn) increased with the increasing use level of biogas residue , their relationship was rising straight-linearly, the application of biogas residue in season would′t cause the risk of heavy metal pollution in Chinese cabbage , but we couldn′t rulr out the potential risk of heavy metals pollution in Chinese cabbage with long-term application of accumulation of heavy metals in the soil;From the accumulation of heavy metals in soil ,comparing with non-fertilizer and only chemical fertilizer treatments , application of biogas residue on the basis of chemical fertilizer could increase the content of total Cr ,total Cu ,total Zn in soil,the relationship with the increasing use of biogas residue was also straight -linearly,a large number of long-term use of biogas residue could lead to soil heavy metal pollution risk .Under the same dosage conditions ,bio-gas residue as organic fertilizer security risk was greater than the pig manure .关键词
