摘　　要：为解决樟树(Cinnamomum camphora)缺铁黄化问题,在砂培条件下研究了樟树铁肥硫酸亚铁铵与柠檬酸、硼酸、复合氨基酸、醋酸、生长素A(萘乙酸)+细胞分裂素、生长素B(吲哚丁酸)+细胞分裂素材料配施对樟树铁不同器官含量和生长的影响。通过分析樟树幼苗地上部、根部和植株的鲜重、干重、含水量、鲜基和干基的根冠比及铁含量,发现硫酸亚铁铵的最佳配料为硼酸,其最佳施用浓度为0.5%。In order to solve the problem of iron deficiency of the camphor tree,the effects of ammonium ferrous sulfate and citric acid,boric acid,compound amino acid,acetic acid,NAA+BA,IBA+BA on the content and growth of different organs of camphor tree were studied in sand culture experiment.By analyzing fresh weight,dry weight,water content and total Fe content in shoots,root and plant,and dry and fresh root shoot ratio of the camphor tree seedlings,it was found that boric acid was the best material applied with ferrous ammonium sulfate and the optimal concentration of boric acid was 0.5%.
