摘　　要：以大豆品种秦豆8号为试验材料,采用盆栽方式,研究锌肥对大豆不同组织生物量、耐性指数、转运指数、锌积累量、锌含量和叶绿素含量的影响。结果表明,15mg/kg锌处理显著提高大豆根和叶片的生物量、叶绿素a含量、叶绿素b含量、类胡萝卜素含量、F_o、F_v、F_m、Zn含量,耐性指数、转运指数和叶片Zn积累量显著增加。综合评价表明,大豆对锌有较好的吸收和富集能力。Pot experiments were used to study the effects of different concentrations of Zn on the biomass, tolerance factor, translocation factor, Zn accumulation in different tissues and Fo, Fv, Fro, the contents of chlorophyll a, chlorophyll b, carotenoids in leaves of soybean at flowering stage. The results indicated that the biomass of leave and root, the contents of chlorophyll a, chlorophyll b and carotenoids, Fo, Fv, Fro, tolerance factor, translocation factor, and Zn accumulation in leaves were gradually increased when the concentration of Zn increased to 15mg/kg, compared with control （non-Zn）. Thus, it was concluded that soybean had high zinc resistance, which was very important for the production of soybean with higher concentration of Zn.
