稀土配合物对大豆幼苗防护(铅)效应试验

Experiment on Protective Effect of Rare Earth Mixture on Glycine Max Seedling

以盆栽试验研究了Pb对大豆苗期素质的影响,及稀土配合物La(镧)-Gly(甘氨酸)的防护效应。试验结果表明,根施500mg·L^(-1)PbAc_2,严重抑制大豆幼苗生长。叶面喷布30mg·L^(-1)La-Gly1次,可减轻Pb对大豆幼苗造成的伤害。

Effect of La-Gly on the growth of Glycine max seedling under Pb stress has been studied through pot culture experiment. The result showed that the growth of Glycine max seedling was inhibited by 500mg/L PbAc2, when 30mg/L La-Gly was used to spray Glycine max seedling once, the damage effect of Pb was reduced.
