| 中文摘要:为了经济、安全、高效地治疗果树因缺铁而引发的黄叶病，克服目前土壤和叶面施铁疗效差，树干注射复绿剂受季节限制、安全性差、操作复杂的缺陷，选用4类8种含Fe化合物（易溶性二价无机铁盐FeSO4·7H2O和FeCl2·4H2O，易溶性三价无机铁盐Fe2(SO4)3和FeCl3·6H2O，难溶性Fe2O3和FeC2O4，铁络合物Fe(NH4)2(SO4)2·6H2O和FeC6O7H6），在树干上打孔后将其塞入。结果表明，多种含铁化合物都能使果树缺铁黄化病在第6至第7天开始复绿，20 d后使已经白化的叶片也能彻底恢复绿色，其中Fe(NH4)2(SO4)2·6H2O最为经济、安全、高效，FeSO4·7H2O次之。 |

| Abstract:Researches selected out eight kinds of iron contained compounds and insert them to the holes dug on the trunks,in order to cure the fruit chlorosis reduced by iron deficiency economically,safely as well as efficiently,and overcome the poor effects of fertilizing iron on soil or tree leaves and the defects of injecting green recovering potion from tree trunks,such as restriction by season,poor safety condition and complex operation.These compounds can be divided into four types including:(1) the soluble inorganic ferrous salt FeSO4·7H2O and FeCl2·4H2O; (2) the soluble inorganic ferric salt Fe2(SO4)3 and FeCl3·6H2O; (3) the hard dissolved iron compounds FeC2O4 and Fe2O3; (4) Iron complex ammonium ferrous sulphate Fe(NH4)2(SO4)2·6H2O and ferrous citrate.The results showed that several iron contained compounds can cure chlorotic disorder of fruit trees caused by iron deficiency within 6-7 days,even the white leaves totally recover to green within 20 days.Fe(NH4)2(SO4)2·6H2O is the most economic,efficient and safest compound; FeSO4·7H2O is the second best．The research also paved a new way for treatment of other trace elements deficiency diseases. |
