| 摘 要： | [目的]研究过量Mg2＋与镁粉尘污染对农作物生长发育情况的影响。[方法]通过在清洁土壤中投加不同浓度的MgCl2试剂和轻烧镁粉尘,经过27 d的培养,期间分4次测定植物生长发育情况指标。[结果]Mg2＋对叶绿素有先激活再抑制的现象,而对根系活力则表现出先抑制再激活,但是Mg2＋达到5.0 mg/g时,根系活力下降。[结论]MgO随着浓度和时间的双重作用影响植物生理活动。 |
| 关 键 词： | Mg2＋ 玉米幼苗 生态毒理指标 叶绿素 根系活力 |

| Abstract: | [Objective] The effect of the pollution of excessive Mg2+ and magnesium dust on cropgrowth and development was researched.[Method] The development indicator of maize plant grown in soil,which was added with the different concentrations of MgCl2 reagent and lightly burned magnesium dust,was measured for 4 times after 27 days' culture.[Result] The effect of Mg2+ on the chlorophyll development was firstly activation and then inhibition and on the root activity was firstly inhibition and then activation,however... |
