| 摘 要： | 以不同果菜为材料,在露天栽培条件下土施和喷施海藻碘肥,探讨果菜类代表性蔬菜品种对碘的吸收和积累特性,以及两种碘肥施用方式下蔬菜碘吸收的差异。结果表明,供试果菜可食部位对碘的吸收均随着海藻碘肥添加浓度的提高而增加。随着取样时间的延长,蔬菜可食部位对海藻碘的吸收除了大豆外均总体呈现下降的趋势。两种不同的海藻碘肥施用方式中,土施更有利于蔬菜对碘的吸收和积累。在土施条件下,碘在果菜不同部位的分配表现为根＞叶＞茎＞果实；在海藻液体碘肥喷施条件下则是叶子的碘含量最高,其次为茎,而果实和根中碘积累量较低。

| Abstract: | The aim of this study was to evaluate the effect of seaweed iodine absorption and accumulation on fruit vegetables in field experiments under two different application techniques(root application and ex-root application).The results showed that the iodine in the edible parts of fruit vegetable increased with the increasing iodine addition in soil.The iodine in edible parts of vegetable decreased with the sampling time except soybean.Under two different application techniques(root application and ex-root app... |
