摘要
通过实验模拟研究了铜(Cu)污染对小麦生长状况有效性的规律.结果发现,铜(Cu)污染与小麦种子萌发、株高有很好的相关性,呈低促高抑效应.作为营养元素,铜(Cu)浓度在300mg/kg时,出苗率、株高、生物量都达到最大值;生物量与铜(Cu)浓度呈弱相关.
A soil-culture experiment was carried out to explore the law of effectiveness about Cu on growing conditions of wheat. The results showed that Cu pollution could inhibit the seedling growth and the height of the wheat when the concentration of Cu〉300mg/kg,and they have a high correlationship. However,the weight of crops do not have such high relationship with Cu concentration.
