| 使用紫阳中地大的硒矿粉肥料，研究不同施硒浓度对黄瓜产量和品质因子的影响，以期为生产富硒黄瓜提供理论依据。以黄瓜品种“真绿202”为试材，土壤根施紫阳中地大的硒矿粉肥料，设置不同施硒浓度试验（0、1、1.5、3、5、10 mg/kg等6个浓度），待黄瓜果实达到可食用标准时，测定黄瓜株高、果实质量、纵横径、可溶性固形物质量分数、酸度、维生素C、硒含量。结果表明，施硒浓度越高，黄瓜果实含硒量也越高。各处理的黄瓜果实含硒量较对照硒含量增加幅度为9～147倍，株高较对照降低34%～70%，单果质量较对照降低36%～85%，可溶性固形物、有机酸、维生素C含量均受到不同程度的影响。除处理1外，其他处理的可溶性固形物较对照显著性降低，处理5的有机酸含量显著性低于其他处理，各处理间维生素C含量差异不显著。研究表明，施硒对黄瓜的产量和品质因子均有一定的影响。 |

| Using selenium mineral powder fertilizer produced by Ziyang Zhongdida Selenium Technology Co., Ltd., this study investigates the effects of different selenium concentrations on cucumber yield and quality parameters, in order to provide a theoretical basis for the production of selenium-enriched cucumbers. The cucumber variety ‘Zhenlu 202’ was used as the experimental material. Selenium mineral powder fertilizer from Ziyang was selected, and cucumber plants were subjected to treatments with different selenium concentrations (1 mg/kg, 1.5 mg/kg, 3 mg/kg, 5 mg/kg, and 10 mg/kg; five concentrations in total). Measurements were taken once the fruits reached the edible maturity stage, including plant height, fruit length, diameter, soluble solids content, acidity, vitamin C content, and selenium content. The results showed that higher selenium concentrations led to increased selenium accumulation in cucumber fruits. The selenium content in the fruits was 0.5,1.8, 6.6, 8.8, and 21.3 times higher than the selenium-enriched standard (0.02 mg/kg), respectively. The selenium content in the control group was only 0.003 mg/kg, which did not meet the selenium-enriched vegetable standard. However, the yield and fruit traits of the control group were superior to those of the selenium-treated groups. Selenium application affected both the yield and quality parameters of cucumber. With increasing selenium concentrations, the selenium content of cucumber fruits increased, while plant height, individual fruit weight, soluble solids, organic acid content, and vitamin C content were negatively affected to varying degrees.The optimal selenium concentration that supports cucumber growth while meeting the selenium-enriched vegetable standard requires further investigation. |
