The problem of heavy metal pollution of crops occurs frequently, and heavy metal pollution has become one of the important factors affecting crop quality. By applying 0.75, 1.50 and 3.00 g/kg potassium sulfate into soil under cadmium (Cd) stress, the effects of potassium fertilizer on the physical and chemical properties of rhizosphere soil and cadmium accumulation in plants of Ilex asprella were studied. This study is expected to lay a foundation for the development of cadmium excess reduction technology in Ilex asprella. The result shows that, the application of high amount of potassium sulfate fertilizer could reduce the soil pH by 1.72% to 8.09%. Cadmium stress can reduce the content of soil organic matter, and the application of medium (1.50 g/kg) and high (3.00 g/kg) amount of potassium sulfate can increase the content of soil organic matter, total potassium and available potassium. In addition, the application of potassium sulfate generally increased the content of biologically available cadmium in the soil, only on the 30th day after the application of low concentration of potassium sulfate (0.75 g/kg), the content of bioavailable cadmium in the soil decreased by 1.94% compared with the Cd treatment group. Under cadmium stress, the application of potassium sulfate could increase the SOD activity in leaves of Ilex asprella, and then enhance the tolerance to cadmium stress. Low could increase the SOD activity in leaves of Ilex asprella, and then enhance the tolerance to cadmium stress. Low concentration of potassium sulfate (0.75 g/kg) inhibited the transport of cadmium from rhizome to leaf and effectively reduce the accumulation of cadmium in the root and stem of Ilex asprella. To sum up, the application of high amount of potassium fertilizer decreased the soil pH, and the application of medium (1.50 g/kg) and high (3.00 g/kg) amount of potassium sulfate could increase the content of soil organic matter, total potassium and available potassium, thus improved soil fertility. The results also showed that low concentration of potassium sulfate could reduce the content of bioavailable cadmium in soil, inhibit the transport of cadmium from roots and stems to leaves, and reduce the accumulation of cadmium in roots and stems of Ilex asprella.

重金属污染已成为影响作物品质的重要因素之一。通过土壤镉(Cd)胁迫下施加0.75、1.50、3.00 g/kg三种浓度硫酸钾,研究硫酸钾对岗梅根际土壤理化性质和岗梅植株中镉积累的影响。结果表明,施用高浓度硫酸钾肥会使土壤pH下降,降低幅度最高达8.09%。镉胁迫会使土壤有机质含量降低,施用中(1.50 g/kg)、高(3.00 g/kg)浓度硫酸钾肥可以提高土壤有机质含量、全钾含量和速效钾含量。施用硫酸钾普遍提高了土壤中生物有效态镉含量,只有施用低浓度硫酸钾(0.75 g/kg)第30天,土壤中的生物有效态镉含量相比Cd处理组降低1.94%。在镉胁迫下,施加硫酸钾可以提高岗梅叶的SOD活性,进而提升对镉胁迫的耐受性。低浓度硫酸钾(0.75 g/kg)可以抑制岗梅植株内的镉从根和茎向叶片转运,且可以有效地减少镉在岗梅根和茎中的积累。因此,施用高浓度钾肥会使土壤pH下降;施用中(1.50 g/kg)、高(3.00 g/kg)浓度硫酸钾肥可以提高土壤有机质含量、全钾含量和速效钾含量,从而提高土壤肥力;低浓度硫酸钾可以降低土壤中生物有效态镉含量,可以较好抑制岗梅植株内的镉从根、茎向叶片转运,且可以较好地减少镉在岗梅根和茎中的积累。

重金属污染已成为影响作物品质的重要因素之一。通过土壤镉(Cd)胁迫下施加0.75、1.50、3.00 g/kg三种浓度硫酸钾,研究硫酸钾对岗梅根际土壤理化性质和岗梅植株中镉积累的影响。结果表明,施用高浓度硫酸钾肥会使土壤pH下降,降低幅度最高达8.09%。镉胁迫会使土壤有机质含量降低,施用中(1.50 g/kg)、高(3.00 g/kg)浓度硫酸钾肥可以提高土壤有机质含量、全钾含量和速效钾含量。施用硫酸钾普遍提高了土壤中生物有效态镉含量,只有施用低浓度硫酸钾(0.75 g/kg)第30天,土壤中的生物有效态镉含量相比Cd处理组降低1.94%。在镉胁迫下,施加硫酸钾可以提高岗梅叶的SOD活性,进而提升对镉胁迫的耐受性。低浓度硫酸钾(0.75 g/kg)可以抑制岗梅植株内的镉从根和茎向叶片转运,且可以有效地减少镉在岗梅根和茎中的积累。因此,施用高浓度钾肥会使土壤pH下降;施用中(1.50 g/kg)、高(3.00 g/kg)浓度硫酸钾肥可以提高土壤有机质含量、全钾含量和速效钾含量,从而提高土壤肥力;低浓度硫酸钾可以降低土壤中生物有效态镉含量,可以较好抑制岗梅植株内的镉从根、茎向叶片转运,且可以较好地减少镉在岗梅根和茎中的积累。

The problem of heavy metal pollution of crops occurs frequently, and heavy metal pollution has become one of the important factors affecting crop quality. By applying 0.75, 1.50 and 3.00 g/kg potassium sulfate into soil under cadmium (Cd) stress, the effects of potassium fertilizer on the physical and chemical properties of rhizosphere soil and cadmium accumulation in plants of Ilex asprella were studied. This study is expected to lay a foundation for the development of cadmium excess reduction technology in Ilex asprella. The result shows that, the application of high amount of potassium sulfate fertilizer could reduce the soil pH by 1.72% to 8.09%. Cadmium stress can reduce the content of soil organic matter, and the application of medium (1.50 g/kg) and high (3.00 g/kg) amount of potassium sulfate can increase the content of soil organic matter, total potassium and available potassium. In addition, the application of potassium sulfate generally increased the content of biologically available cadmium in the soil, only on the 30th day after the application of low concentration of potassium sulfate (0.75 g/kg), the content of bioavailable cadmium in the soil decreased by 1.94% compared with the Cd treatment group. Under cadmium stress, the application of potassium sulfate could increase the SOD activity in leaves of Ilex asprella, and then enhance the tolerance to cadmium stress. Low could increase the SOD activity in leaves of Ilex asprella, and then enhance the tolerance to cadmium stress. Low concentration of potassium sulfate (0.75 g/kg) inhibited the transport of cadmium from rhizome to leaf and effectively reduce the accumulation of cadmium in the root and stem of Ilex asprella. To sum up, the application of high amount of potassium fertilizer decreased the soil pH, and the application of medium (1.50 g/kg) and high (3.00 g/kg) amount of potassium sulfate could increase the content of soil organic matter, total potassium and available potassium, thus improved soil fertility. The results also showed that low concentration of potassium sulfate could reduce the content of bioavailable cadmium in soil, inhibit the transport of cadmium from roots and stems to leaves, and reduce the accumulation of cadmium in roots and stems of Ilex asprella.
