| 摘 要： | 采用盆栽试验的方法,研究施用猪粪对土壤和菜心砷含量的影响。结果表明,随猪粪施用量的增加,土壤全砷、有效态砷和菜心砷含量均提高,且均与猪粪施用量呈极显著的正相关。施用猪粪的同一处理相比较,第2茬土壤全砷、有效态砷和菜心砷含量均高于第1茬。相关分析表明,施用猪粪导致土壤有效态砷含量提高是菜心砷含量增加的主要原因,土壤有效态砷含量可以作为衡量猪粪安全施用的指标。

| Abstract: | Pot experiment was conducted to study the influence of applying pig manure on arsenic content of soil and Brassica campestris.The results showed that the content of total,available arsenic in soil and in Brassica campestris increased with pig manure dose raised from 5 g/kg to 60 g/kg.There existed positively significant correlation between the content of total,available arsenic in soil,arsenic in Brassica campestris and pig manure dose.The content of total,available arsenic in soil and in Brassica campestri... |
