摘要
通过盆栽和小区试验初步探讨了污泥复合肥对蔬菜的增产效应及其对蔬菜吸收累积重金属的影响。结果表明 ,污泥复合肥可显著提高蔬菜产量 ,蔬菜可食部分中的Cu、Zn、Cd含量均在国家食品卫生标准范围内 。
The pot and plot experiments to study the effect of sewage sludge compost and sewage sludge compound fertilizers on vegetables yield and heavy metal accumulation in vegetables. The results showed that sewage sludge compound fertilizer increased the vegetable yield and the heavy metal (copper, zinc and cadmium) contents in the esculent part of vegetables were lower than those of the national control standard, but the lead contents in the cauliflower and lettuce were higher than the national control standard.
