摘要
铁胁迫致苹果黄叶时进行根系输铁液能在较短时间内提高叶片叶绿素和铁的含量从而达到复绿的效果。在Ｆｅ－Ｃｉｔｒｉｃ ａｃｉｄ、Ｆｅ－ＥＤＴＡ 和Ｆｅ－Ｎ ３ 种铁肥中，Ｆｅ－Ｎ 是适宜根系输液的铁肥品种，主干强力高压注射铁肥复绿较慢，叶面喷布效果不显著。
Apple chlorosis caused by iron deficiency stress can be improved in short time by raising the content of chloropyll and iron in leaves when iron fertilizer is inserted into roots.Among Fe Citric acid,Fe EDTA and Fe N the best effect was obtained by Fe N.It takes more time to improve chlorosis when iron fertilizer is intensively injected into trunk.The effect of spray is not obvious.
