摘要

采用盆栽试验

探讨了湖泊底泥与无机肥料配合施用对土壤化学性质和冬小麦籽粒重金属Cd的影响。结果表明

二者交互不同处理均能增加土壤养分含量

虽然重金属Cd、Pb、Cu、Zn含量有所增加

但土壤仍清洁或尚清洁

不同处理小麦籽粒中Cd含量未超出我国食品中重金属限量卫生标准

本试验条件下

湖泊底泥以200 t/hm^2和无机肥料以150 kg/hm^2（尿素）＋150 kg/hm^2（磷酸二铵）配合施用为安全经济施肥量。

Abstract

The pot experiments were conducted to study the effects of lake sediment and inorganic fertilizer combined application on soil chemical properties and heavy metal(Cd) of winter wheat seed.The results showed that content of nutrients could be increased in the soil by combined application of lake sediment and inorganic fertilizer

although content of heavy metals(Cd

Zn) could be increased

the soil was clean.The content of heavy metals of Cd in wheat seed of different treatments were not exceeded the National Control Hygienic Standard for Foods

the amount of combined application was the safe and economical

if lake sediment was 200 t/hm2 and inorganic fertilizer was 150 kg/hm2(CO(NH_2)_2) 150 kg/hm2((NH_4)_2HPO_4).
