Abstract:

采用15N示踪技术与沙培相结合的方法,以最适锰浓度为对照,设置锰缺乏(分别为对照浓度的1/25和1/5作为重度和轻度锰缺乏处理)和锰过量(分别为对照浓度的5倍和25倍作为轻度和重度锰过量处理)4个锰胁迫处理,研究了锰胁迫对大豆氮素积累的影响。结果表明:与对照相比,锰胁迫并未明显影响生育前期大豆植株氮素积累,但对中后期氮素积累起显著抑制作用(P<0.01),并且抑制作用随胁迫程度的加深而加重;锰胁迫对苗期(V4)肥料氮的积累无影响,但对其他生育时期肥料氮的积累均表现出不同程度的抑制作用;在整个生育期间,锰胁迫显著抑制了根瘤固氮的积累,大幅度减少了鼓粒期间根瘤固氮的积累;锰胁迫不仅显著减少了成熟期(R8)大豆营养器官和子粒中肥料氮、根瘤固氮、总氮的积累,还在一定程度上增加了营养器官中肥料氮、根瘤固氮、总氮的积累比例,子粒则相应减小。综合分析表明,锰胁迫对大豆肥料氮、根瘤固氮、以及总氮的积累均有抑制作用,抑制效果在大豆生育中后期表现明显,并且锰胁迫改变了成熟期大豆营养器官和子粒中肥料氮、根瘤固氮和总氮的积累比例。本试验所得结果丰富了锰胁迫与大豆氮素营养的相关研究内容,并为进一步的机理研究奠定了基础。
