摘要

In order to explore the effects of combined foliar spray which was prepared from potassium fulvate and Zn on heavy metal accumulations in three kinds of facility fruit vegetables,cucumber,tomato and white melon,the foliar spray was applied from fruit setting to maturation.The results showed that the combined foliar spray significantly promoted the absorption of Zn and Cu in the three fruit vegetables,blocked the absorption of Cr,As and Pb in cucumber,significantly blocked the absorption of Cd in white melon,blocked the absorption of Pb in white melon,and showed a tendency of blocking the absorption of heavy metals Cd and As in tomato.
