A field survey and greenhouse experiments were conducted using Physalis alkekengi L. to investigate strategies of phytoremediation. In addition, ZnO nanoparticles were synthesized using P. alkekengi. P. alkekengi plants grew healthily at Zn levels from 50 to 5000 mg kg(-1) in soils. The plants incorporated Zn into their aerial parts (with mean dry weight values of 235-10,980 mg kg(-1)) and accumulated biomass (with a mean dry weight of 25.7 g plant(-1)) during 12 weeks. The synthesized ZnO nanoparticles showed a polydisperse behavior and had a mean size of 72.5 nm. The results indicate that P. alkekengi could be used for the remediation of zinc-contaminated soils. Moreover, the synthetic method of synthesizing ZnO nanoparticles from Zn hyperaccumulator plants constitutes a new insight into the recycling of metals in plant sources.
采用酸浆（Physalis alkekengi L.）进行田间调查和温室实验，以研究植物修复策略。此外，还使用酸浆合成了氧化锌纳米粒子。在土壤中锌浓度为 50 至 5000mg/kg 的条件下，酸浆植株生长健康。植物将锌纳入其地上部分（平均干重值为 235-10980mg/kg）并在 12 周内积累生物量（平均干重为 25.7g/株）。合成的氧化锌纳米粒子表现出多分散行为，平均粒径为 72.5nm。结果表明，酸浆可用于修复锌污染土壤。此外，利用 Zn 超积累植物合成 ZnO 纳米粒子的方法为植物资源中金属的回收提供了新的思路。
