摘要
为探讨叶面喷施不同铁营养剂对防治花生缺铁性黄化及产量的作用效果,在田间试验条件下,研究了喷施不同有机酸和铁复混制剂对花生叶片活性铁含量与SPAD值(叶绿素相对含量)及产量的影响。结果表明,与喷施清水或硫酸亚铁溶液相比,喷施黄腐酸铁、柠檬酸铁和氨基酸铁三种复混制剂,能够有效提高花生新展开叶片SPAD值和活性铁含量,以黄腐酸铁复混制剂处理效果最好,其次是氨基酸铁复混制剂处理。叶面喷施不同有机酸与铁复混制剂促进花生生长发育效果显著,喷施黄腐酸铁、柠檬酸铁、氨基酸铁处理比喷施清水处理分别增产10.5%、9.4%、12.2%。喷施黄腐酸铁或氨基酸铁复混制剂是防治花生缺铁性黄化和增加花生产量的有效措施。
To discuss the effects of spraying application of foliar Fe-fertilizer on Fe chlorosis and yield of peanut,a field experiment was conducted to study the effect of different foliar Fe-organic acid complex spraying application on active iron content,SPAD values and yield of peanut.The results showed that spraying of Fe-fulvic acid,Fe-citric acid and Fe-amino acid complex were effective on enhancing active acid and chlorophyll content in peanut fresh leaves,compared with treatment of spraying water and FeSO4.The Fe-fulvic acid complex treatment showed the best result,the next was the Fe-amino acid complex treatment.Besides,spraying of different foliar Fe-organic acid complex could improve peanut growth and development,and spraying of Fe-fulvic acid,Fe-citric acid and Fe-amino acid complex increased yield by 10.5%,9.4%,12.2%respectively compared with spraying treatment of water.Overall,spraying of Fe-fulvic acid and Fe-amino acid complex were effective methods on controlling Fe chlorosis and increasing yield of peanut.
