铁肥虹吸输液方法对矫正苹果缺铁失绿症的影响
Journal of Fruit Science(2013)
Abstract
[目的]为了探索苹果叶片缺铁失绿矫正新方法,[方法]通过田间试验和盆栽试验,分别研究了铁肥虹吸输液对矫正苹果缺铁失绿症的影响,铁肥虹吸输液和强力高压注射对叶片和根中铁含量的影响及铁在树体内的运输与分布.[结果]结果表明,铁肥虹吸输液能够在较短时间内使黄化的叶片复绿,显著增加叶片中叶绿素含量.虹吸输液增加叶片中铁含量显著多于强力高压注射,强力高压注射增加根中铁含量显著高于虹吸输液,虹吸输液铁肥靠叶片蒸腾拉力进入树体,强力高压注射的铁肥靠压力进入树体.[结论]铁肥虹吸输液是矫正苹果缺铁失绿症一种新的高效、简单易行方法.
