在温室条件下，采用完全随机设计，研究了5种盐浓度和4种铜浓度对巴达米阿月浑子幼苗生长和化学成分的影响。在种植后第24周测定生长参数。测定了植株地上部和根系的元素吸收总量。结果表明，盐胁迫降低了叶面积、茎高、地上部和根系干重。施用2.5和5 mg铜（Cu）kg ~（-1）土显著增加了根干重，而对地上部干重和叶面积无显著影响。施铜量为7.5mg·kg ~（-1）时，对茎高有负效应。盐胁迫降低了地上部和根系对Cu和P的吸收量，但增加了地上部和根系对Na和Cl的吸收量。铜增加了地上部和根系对Cu的吸收总量、根系对P的吸收总量和地上部对Na的吸收总量，但降低了地上部对Cl的吸收总量。
The effects of five salinity levels and four Cu levels on growth and chemical composition of Badami pistachio seedlings were studied under greenhouse conditions in a completely randomized design with three replications. Growth parameters were determined on the 24th week after planting. Total elemental uptake amounts in shoot and root of plant were measured. Results showed that salinity decreased leaf area, stem height, and shoot and root dry weights. Application of 2.5 and 5 mg copper (Cu) kg(-1) soil significantly increased root dry weight, whereas it had no significant effects on shoot dry weight and leaf area. Application of 7.5 mg Cu kg(-1) soil had a negative effect on stem height. Salinity declined shoot and root total Cu and phosphorus (P) uptake amounts but increased shoot and root total sodium (Na) and chlorine (Cl) uptake amounts. Copper increased shoot and root total Cu uptake amounts, root total P uptake, and shoot total Na uptake but decreased shoot total Cl uptake.
