[目的]研究不同浓度的废旧电池浸出液对小麦幼苗生物量及叶绿素的影响, 为预防小麦减产和重金属中毒提供理论依据.[方法]以小麦为试验材料,探讨不同浓度梯度的废旧电池浸出液对小麦幼苗叶绿素及生物量的影响.[结果]当废旧干电池浸出液浓度较低时,其对小麦幼苗生物量的影响很小,而对叶绿素含量在短时间内有一定的促进作用.当废旧电池浸出液浓度较高时,明显抑制小麦幼苗叶绿素的增加,但对小麦幼苗生物量的影响并没有明显的规律性.[结论]废旧电池浸出液对小麦幼苗的生长影响很大.%[Objective] The theoretic reference for the prevention of wheat yield-reducing and toxicity of heavy metal to wheat was provided through the research on the effect of the different concentrations of waste batteries leaching on the chlorophyll and biomass of wheat seedling. [Method] The wheat being taking as the experimental material, the effects of the different concentrations of waste battery leaching on the chlorophyll and biomass of wheat seedling was discussed. [Result] The results showed that low concentration of waste batteries leaching could little affect the biomass of wheat seedling, however, it could facilitate the increase of chlorophyll content of wheat seedlings in a short time. When the waste battery leaching was relatively high, the chlorophyll development was significantly inhibited. There was obvious regularity in the concentrations of waste battery leaching affecting the biomass of wheat seedling. [Conclusion] The waste battery leaching heavily affected the wheat seedling growth.
