摘要:

为探究不同种类蔬菜在碱性镉超标土壤中的镉富集能力,以便筛选出镉低积累的蔬菜品种。本试验选择了4种叶菜类、8种茄果类和3种根茎类等15种常见当季蔬菜,蔬菜成熟后取可食用部分检测分析。试验结果表明,3种根茎类蔬菜镉含量都未超过0.1 mg·kg-1;4种叶菜类蔬菜镉累积都超过0.1 mg·kg-1,香菜镉含量最高;茄果类蔬菜中秋葵镉含量最高,茄子次之,其余都未达到0.1 mg·kg-1。从富集系数上来看,香菜和秋葵分别达到60.02%和13.69%,有一定的富集作用,其余蔬菜富集作用不明显。在镉含量超标的碱性土壤中,可以选择种植南瓜、长蒲和黄瓜。

Abstract:

To explore the cadmium enrichment ability of different types of vegetables in alkaline soil with excessive cadmium content, and to screen out vegetable varieties with low cadmium accumulation, this experiment selected a total of fifteen common seasonal vegetable varieties, including four types of leafy vegetables, eight types of Solanaceous fruits, and three types of root and tuber vegetables. After the vegetables matured, edible parts were taken for testing and analysis.The experimental results showed that the cadmium content in three types of root and tuber vegetables did not exceed 0.1 mg·kg-1; The cadmium content in four leafy vegetables exceeded 0.1 mg·kg-1, with coriander having the highest cadmium content. The cadmium content in Solanaceous fruits was highest in the okra, followed by eggplant, and the cadmium content in the rest Solanaceous fruits was below 0.1 mg·kg-1. From the perspective of enrichment coefficients, coriander and okra reached 60.02% and 13.69%, respectively, indicating a certain enrichment effect, while the enrichment effects of other vegetables were not significant. In alkaline soil with excessive cadmium content, pumpkin, cattail, and cucumber can be planted as options.
