为探索镉胁迫对芹菜产量和氮、磷、钾吸收及镉积累量的影响，采用盆栽试验方法，研究不同镉水平胁迫的芹菜产量和氮、磷、钾吸收及镉积累量的变化。结果表明，随着镉胁迫程度加重，芹菜心叶生长缓慢，甚至干枯萎缩，而外部叶片表现不明显；镉胁迫由轻到重时芹菜茎基直径和叶柄横径明显下降，芹菜减产2.21%~19.74%，氮、磷、钾吸收量低镉胁迫略有增加，中高镉胁迫时缓慢下降；芹菜镉吸收量随镉胁迫浓度增加而增加，低镉胁迫时芹菜镉质量分数已达到0.097 mg/kg（鲜重），超过国标（0.05 mg/kg（鲜重））1.94倍。

A pot experiment of different calcium on yield and cadmium uptake of Apium graveolens under cadmium stress was carried out to probe into effect of Cadmium stress on yield,nitrogen, phosphorus, potassium and cadmium uptake of Apium graveolens .The results showed that inner leaves of Apium graveolens grew slowly or wither under cadmium stress, but withering symptom in the outer leaves of Apium graveolens alleviated. The stem diameter and petiole diameter of Apium graveolens dramatically declined, their yield reduced from 2.21% to 19.74%, content of nitrogen phosphorus and potassium in Apium graveolens gently decreased along with cadmium stress aggravating. Levels of cadmium in fresh leaves of Apium graveolens was 0.097 mg/kg, beyond the safety qualification threshold level (0.05 mg/kg) for agricultural product safety requirements and original environmental requirements for non-environmental pollution vegetable.
