为了评价ＦｅＳＯ４、Ｆｅ２（ＳＯ４）３、Ｆｅ２Ｏ３、Ｆｅ（ＮＯ３）３和Ｆｅ－ＥＤＴＡ在巴基斯坦钙积干旱土上对水稻产量和化学组成的影响，进行了盆栽试验．结果表明：每千克土壤施用１０和１５ｍｇＦｅ后，５种铁源均使水稻植株株高、稻草产量、总分蘖数、有效分蘖和千粒重明显增加．稻谷和稻草中的铁、氮、钾含量显著增加，而磷、铜、锰则减少，不同铁化合物对水稻生长和水稻植物养分含量相对影响次序为Ｆｅ－ＥＤＴＡ＞Ｆｅ２ＳＯ４＞Ｆｅ（ＮＯ３）３＞Ｆｅ２（ＳＯ４）３＞Ｆｅ２Ｏ３．
In order to evaluate the effects of FeSO4, Fe2 (SO4) 3, Fe2O3, Fe (NO3) 3 and Fe-EDTA on the yield and chemical composition of rice in Calcium plot arid soil in Pakistan, pot experiments were conducted. The results showed that the plant height, straw yield, total tiller number, effective tiller and 1000-grain weight of rice plants increased significantly after applying 10 and 15 mg Fe per kg of soil. The content of iron, nitrogen and potassium in rice and straw increased significantly, while the contents of phosphorus, copper and manganese decreased. The order of Fe-EDTA> Fe2SO4> Fe (NO3) 3> Fe2 (SO4) 3> Fe2O3.
