| 摘 要： | 为确定土壤铜、硫污染对苹果幼树生长发育的影响,以硫铁矿尾矿砂河滩垫地上栽植的苹果幼树为试材,研究土壤中的不同铜硫含量对苹果幼树生长发育的影响.结果表明:土壤中的铜含量≥46.8mg/kg,土壤有效硫含量≥368.7 mg/kg时,苹果幼树的生长发育就会受到抑制;土壤中的铜含量≥53.9mg/kg,土壤有效硫含1量≥538.0 mg/kg时,苹果幼树受毒害甚至死亡.苹果幼树各器官铜含量的分布规律为:根系>叶片>新梢>1年生技>2年生枝>主干,硫含量分布规律为:叶片>根系>新梢>1年生枝>2年生枝>主干.正常树的长、中、短枝数量分别是轻度受害树的2.02,1.37,1.04倍,是重度受害树的3.30,2.22,1.47倍,是受害死亡树的37.60,4.73,2.30倍.生长正常树的花芽数为518个,显著高于轻度受害树的,极显著高于重度受害树的.生长正常树的萌芽率为60.67%,分别是轻度受害树、重度受害树的1.43,2.22倍.

| Abstract: | To confirm the effects of soil copper and sulfur pollution on growth of young apple trees,the young apple trees which were planted in the flood land filled by pyrite iron sand were used as materials to study the effects of soil copper and sulfur contents on growth of young apple trees.The results showed that:The growth of apple trees would be inhibited when the soil copper content was more than 46.8 mg/kg and the soil available sulfur was more than 368.7 mg/kg.The apple trees would be poisoned or death when... |
