摘    要: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.

关 键 词:石灰性土壤;水稻;铁化合物;巴基斯坦

Abstract:In a pot experiment, five iron containing compounds i.e., FeSO 4 , Fe 2 (SO 4) 3 , Fe 2O 3 , Fe(NO 3) 3 , and Fe EDTA were applied at the levels of 10 and 15 mg Fe kg -1 soil to evaluate their effect on growth, yield components, and chemical composition of rice variety basmati 385 under alkaline calcareous soil conditions. The results indicated that application of iron compounds at both the levels significantly increased plant height, straw yield, number of total and fertile tillers pot 1 and 1 000 grain weight over control. A significant increase in iron, nitrogen, potassium, and decrease in phosphorus, copper, manganese,and zinc contents of paddy and straw was observed. The relative efficiency of various iron compounds in affecting growth and nutrient contents of plants varied in the order: Fe EDTA > Fe SO 4 > Fe(NO 3) 3 > Fe 2 (SO 4) 3 > Fe 2 O 3 .
Keywords:calcareous soil  rice  iron compounds  Pakistan
