摘要
采用盆栽和小区试验,研究了在石灰性土壤中镍污染对小麦和水稻的影响;两种作物对土壤中镍的吸收、迁移和累积规律。建议农田污泥施肥时镍的控制标准为330PPm。
Both pot and plot tests were carried out to study the effects of nickel on wheat and rice grown on calcareous soil with nickel containing sludge applied. It appeared that wheat was more sensitive than rice and a 10% reduction in yield was caused when the soil content of nickel reached 130 ppm. It was concluded that the critical value of nickel content in calcareous soil is 155 ppm and 330 ppm should be the maximum permissible nickel contents in sludge for application.
