In Pb-factored soils, soil application of appropriate inorganic amendment along with cultivation of salt-tolerant crop species/genotypes for Pb immobilization can be a good choice. Hence, in saline-sodic and non-saline/sodic Pb-factored soils, Pb immobilization was observed as influenced by exogeneously applied inorganic amendments. Salt-tolerant rice cultivar Shaheen basmati was grown in present study. The current pot study consists of two factors: three inorganic amendments (i.e., gypsum, rock phosphate and di-ammonium phosphate) each with their three increasing rates along with uncontaminated and contaminated controls, and two types of Pb-factored soils (non-saline/sodic and saline–sodic). At harvest maturity, crop was reaped and straw, paddy yields and height of plant were noted. The results showed that Pb induced decrease in rice growth and physiological attributes (i.e., transpiration rate, photosynthetic rate, stomatal conductance, chlorophyll a, b and carotenoids) were significantly (p ≤ 0.05) counteracted by exogeneously applied inorganic amendments. Among the tested amendments, the highest gypsum application rate of 9 me Ca 100 g⁻¹ soil was proved the most effective to improve rice growth, yield, physiological functions, and to reduce Pb concentration in rice both in saline-sodic and non-saline/sodic Pb-factored soils.

在铅污染的土壤中，在土壤中施用适当的无机改良剂以及种植耐盐的作物物种/基因型以固定铅是一个不错的选择。因此，在盐碱和非盐/碱铅形成的土壤中，观察到Pb的固定受外源施加的无机改性剂的影响。在本研究中种植了耐盐水稻品种Shaheen basmati。当前的盆栽研究包括两个因素：三种无机改良剂（即石膏，磷酸盐岩和磷酸二铵），每种均以其三种增加的速率以及未受污染和受污染的对照物，以及两种类型的Pb分解土壤（无盐） / sodic和盐水-sodic）。在收获成熟时，收割了农作物，并记录了稻草，水稻产量和植物高度。一个，b和类胡萝卜素）为显著（p 由exogeneously施加无机修正抵消≤0.05）。在测试的修订中，最高的石膏施用量为9 me Ca 100 g ^-1土壤，被证明对盐碱和非盐碱都能最有效地改善水稻生长，产量，生理功能并降低水稻中的Pb浓度。 /钠铅污染的土壤。
