摘要: 以甜菜作为供试材料,在营养液中添加不同浓度的Cd2 ,研究重金属镉对甜菜微量元素营养吸收影响,为进一步研究镉污染对甜菜生长的影响提供基础数据,为甜菜安全生产提供科学依据。结果表明:(1)随着Cd2 浓度增加,甜菜幼苗逐渐褪绿变黄,幼苗干鲜重降低;(2)镉胁迫后甜菜幼苗吸收Cd2 浓度呈增加趋势;(3)在营养液中添加Cd2 ,致使根、茎、叶中的硼、铜、锌、铁、锰、钼都发生不同程度的改变,其含量有的增加、有的减少。在营养液中由于镉元素的存在,影响甜菜的营养吸收,破坏了营养平衡致使甜菜生长发生改变,产生不同程度的危害。随着营养液中Cd2 浓度增加,甜菜幼苗受到危害变重,镉影响明显。

Abstract: The authors studied the effect of cadmium on the nutrient uptake of microelements in sugar beet by adding different concentrations of Cd2 ions in the nutrient solution, in order to provide basic data for further understanding the effects of cadmium pollution on sugar beet growth, and provide a basis for the safe production of sugar beet. The results showed that: (1) with the increase of Cd2 concentration, sugar beet seedlings gradually faded and yellowed, and the dry and fresh weight of the seedlings decreased; (2) Cd2 ion concentration in sugar beet seedlings increased under cadmium stress; (3) Cd2 ions were added to the nutrient solution, so that boron, copper, zinc, iron, manganese and molybdenum in root, stem and leaf had different changes, some increased in absorption while some decreased. The presence of cadmium in the nutrient solution could affect the nutrient absorption of sugar beet, destroy the nutrient balance resulting in the change of sugar beet growth and various degrees of harm. With the increase of Cd2 concentration in the nutrient solution, the sugar beet seedlings were seriously damaged and the effect of cadmium was obvious.
