摘要
为探讨锌和黄腐酸钾组合叶面喷剂对设施果菜重金属累积的影响,选择黄瓜、番茄、白甜瓜坐果到成熟期,进行了组合叶面喷施剂的应用效果试验,研究其对土壤和果蔬7种重金属Cd、Cr、Cu、Pb、Zn、As和Hg累积影响。结果表明:组合叶面喷剂显著促进3种果蔬对Zn、Cu的吸收,阻隔黄瓜对Cr、As、Pb的吸收,显著阻隔白甜瓜对重金属Cd的吸收,阻隔白甜瓜对Pb的吸收,有阻隔番茄中吸收重金属Cd和As的趋势。
In order to explore the effects of combined foliar spray on heavy metal accumulations which made up of fulvic acid potassium and zinc in three kinds of facilitied fruit vegetables-cucumber,tomatoes,white melon.Sprayed from bear fruit period to mature.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 had the trend of blocking the absorption of heavy metal Cd and As in tomato.
