研究了铜对绿豆(Vigna Radiata(L.)Wilczek)在玻璃屋的陶罐实验中。以不同浓度(0、50、100、150、200和250 mg·kg-1)的硫酸铜(CuSO4.5H2O)形式向土壤中施铜，种植绿豆。植物样品在播种后45天进行分析。结果表明，低浓度铜(50 mg kg-1)对绿豆的生长、干物质产量和养分含量均有显著的促进作用，而高浓度铜(100~250 mg kg-1)则降低了绿豆的生长、干物质产量和养分含量。关键词：铜，生长，营养含量，绿豆，人参等。铜对绿豆生长、干物质产量和养分含量的影响威尔切克。植物生长因子3/3(2011)53-62。
An attempt was made to study the influence of copper (Cu) on growth, dry matter yield and nutrient content of greengram ( Vigna radiata (L.) Wilczek) in a glass house earthen pot experiment. Copper was applied to the soil in the form of copper sulphate (CuSO 4 .5H 2 O) in different concentrations (0, 50, 100, 150, 200 and 250 mg kg -1 ) in which the greengram plants were grown. The plant samples were analysed 45 days after sowing. The results indicated that low level of copper concentrations (50 mg kg -1 ) showed a significant increase in the overall growth, dry matter yield and nutrient content, while higher concentrations (100-250 mg kg -1 ) decreased the growth, dry matter production and nutrient content of greengram.
