摘要：

为了探究锶(Sr)在生菜中的富集情况，本研究通过实验室种植的方法，设置土培+固态氯化锶、土培+液态氯化锶和水培三种生菜培养方式，对生菜幼苗期、生长期、成熟期、衰老期锶的富集情况进行研究。实验结果表明，3种锶添加方式均可实现生菜中锶的富集。其中，土培方式下，土壤中固态锶添加量从0 mg/kg增至200 mg/kg时，生菜在各个生长阶段的锶含量均显著提高。例如，在幼苗期，生菜的锶含量从2.98 mg/kg增至169.07 mg/kg。在土培+液态氯化锶的模式下，土壤中液态锶浓度从0 mmol/L增至10 mmol/L时，幼苗期锶含量增长最为显著，含量从0.25 mg/kg增至510.24 mg/kg。对于水培模式，水中锶浓度从0 mmol/L增至5 mmol/L时，生菜中锶含量大幅度增长，其中成熟期的增幅最为显著，此时生菜的锶含量可达1008.25 mg/kg。另外，在本实验设置的锶浓度范围内，土培生菜中锶的含量随着添加锶浓度的增加而增加，未出现明显的生长抑制现象；对于水培实验，3 mmol/L被确定为最佳培养浓度，在该浓度下，生菜的生长状况良好且锶的富集效果最佳。该研究验证了实现生菜中锶富集的可行方法，还确定了不同培养模式下的最佳锶浓度，为开发富锶农产品以及为其他农作物进行锶的富集研究提供了参考。

Abstract:

To explore the enrichment of strontium (Sr) in lettuce, this study adopted a laboratory cultivation method and established three cultivation approaches for lettuce: soil culture with solid strontium chloride, soil culture with liquid strontium chloride, and hydroponics. Using these methods, the enrichment of strontium in lettuce was investigated during its seedling, growth, maturity, and senescence stages. The experimental results showed that all three strontium addition methods successfully achieved strontium enrichment in lettuce. Under soil cultivation, when the solid strontium addition in the soil increased from 0 mg/kg to 200 mg/kg, the strontium content in lettuce at all growth stages significantly increased. For instance, the strontium content during the seedling stage rose from 2.98 mg/kg to 169.07 mg/kg; in the mode of soil culture with liquid strontium chloride, the concentration of liquid strontium in the soil increased from 0 mmol/L to 10 mmol/L, and the strontium content increased most significantly during the seedling stage, from 0.25 mg/kg to 510.24 mg/kg. For hydroponics, increasing the strontium concentration in water from 0 mmol/L to 5 mmol/L significantly increased the strontium content in lettuce. The maturity period was most obvious. When the strontium concentration in water was 5 mmol/L, the strontium content in lettuce could reach 1008.25 mg/kg. In addition, in the strontium concentration set in this experiment, the content of strontium in lettuce grown in soil increased with the increase of strontium concentration, and no significant inhibitory effect was observed; for hydroponic experiments, 3 mmol/L was the optimal culture concentration. The study validated the method for strontium enrichment in lettuce and the optimal concentration, providing a reference for strontium enrichment in crops.
