摘要：

采用盆栽试验，研究Pb、As交互作用对青稞品质（脂肪酸、氨基酸、β-葡聚糖、矿质元素）的影响，对保护人体健康具有重要意义。以青稞为供试作物，设置不同浓度Pb (480、720、960、1200 mg/kg)、As (30、60、90、120 mg/kg)交互处理及空白对照组，通过盆栽试验研究对青稞品质的影响。结果表明：在铅添加浓度为480、720、960、1200 mg/kg与砷交互条件下，青稞的β-葡聚糖与空白相比，均表现为抑制作用；氨基酸与空白相比，均表现为促进作用；脂肪酸与空白相比，在铅添加浓度为480 mg/kg与砷交互条件下表现为低促高抑；在铅添加浓度为720、960、1200 mg/kg与砷交互条件下，均表现为促进作用。在铅添加浓度为480、720、960、1200 mg/kg与砷交互条件下，青稞的钾、钠含量与空白相比，均表现为低促高抑，铁、锌含量与空白相比，均表现为促进作用。在铅添加浓度为480、960、1200 mg/kg与砷交互条件下，青稞的镁、钙含量与空白相比，均表现为低促高抑；在铅添加浓度为720 mg/kg与砷交互条件下，青稞的镁、钙含量与空白相比，均表现为抑制作用，在铅添加浓度为480、960 mg/kg与砷交互条件下，青稞的锰含量与空白相比，均表现为促进作用；在铅添加浓度为720、1200 mg/kg与砷交互条件下，青稞的锰含量与空白相比，表现为低抑高促。在铅添加浓度为480 mg/kg与砷交互条件下，青稞的铜含量与空白相比，表现为低促高抑；在铅添加浓度为720、960、1200 mg/kg与砷交互条件下，青稞的铜含量与空白相比，均表现为促进作用。高浓度铅、砷交互作用显著抑制青稞β-葡聚糖含量，相反，显著促进了脂肪酸和氨基酸的含量。铅砷交互作用下青稞中矿质元素含量存在显著性差异，青稞中8中矿质元素含量分布规律依次是钾>镁>钙>钠>铁>锌>锰>铜。

Abstract:

A pot experiment was conducted to study the effects of Pb and As interactions on the quality of highland barley (fatty acids, amino acids, β-dextran and mineral elements). Using highland barley as the experimental crop, different concentrations of Pb (480, 720, 960 and 1200 mg/kg) and As (30, 60, 90 and 120 mg/kg) interaction treatment and blank control were set up for the study. The results showed that, compared with blank, under the interaction conditions of Pb and As, when the concentration of Pb addition were 480, 720, 960 and 1200 mg/kg, β-dextran of highland barley showed inhibition, amino acid showed a promoting effect; when Pb addition concentration was 480 mg/kg, the fatty acid showed low promotion and high inhibition; when pb addition concentrations were 720, 960 and 1200 mg/kg, all showed a promoting effect; when the Pb addition concentrations were 480, 720, 960 and 1200 mg/kg, the K and Na content of highland barley showed low promotion and high inhibition, and the content of Fe and Zn showed a promoting effect; when Pb addition concentrations were 480, 960 and 1200 mg/kg, the Mg and Ca content of highland barley showed low promotion and high inhibition; when the Pb addition concentration was 720 mg/kg, the Mg and Ca content of barley showed inhibitory effects; when the Pb addition concentration were 480 and 960 mg/kg, the Mn content of highland barley showed a promoting effect; when the concentration of Pb addition were 720 and 1200 mg/kg, the Mn content of barley showed low inhibition and high promotion; when the Pb addition concentration was 480 mg/kg, the Cu content of barley showed a low promotion and high inhibition; when the Pb addition concentration was 720, 960 and 1200 mg/kg, the Cu content of highland barley showed a promoting effect. Interaction of high concentration of Pb and As significantly inhibited highland barley β-dextran content, but significantly increased the content of fatty acids and amino acids. There was a significant difference in the content of mineral elements in highland barley under the interaction of Pb and As, the distribution pattern of the content of 8 mineral elements in highland barley was in the order of K>Mg>Ca>Na>Fe>Zn>Mn>Cu.
