Effect of Soil Amendment and Leaf Surface Spraying Selenium on Adsorption of Chinese Cabbage in Cadmium-contaminated Soil
The potted experiment of Chinese cabbage was used to analyze the effects of soil amendment and selenium fertilizer(Se)spraying on Chinese cabbage's adsorption of cadmium(Cd)in Cd-contaminated soil.The results showed that Compared with the control treatment without soil amendment,the combined application of pig manure and lime could increase soil pH value and organic matter content,among which 10.0 g/kg pig manure and 3.0 g/kg lime combined application had the most significant increase in soil pH value.The combined application of 10.0 g/kg pig manure and 1.0 g/kg lime had the best effect on increasing soil organic matter content,and the organic matter content increased by 6.28%.Compared with the treatment without soil amendment,the application of pig manure and lime could reduce the soil available Cd content,in which the combination of 10.0 g/kg pig manure and 3.0 g/kg lime has the most significant effect on the reduction of soil available Cd content,which reduced the soil available Cd content by 35.95%.Leaf spraying with different concentrations of Se fertilizer could promote the antioxidant enzyme activity of Chinese cabbage,and the antioxidant enzyme activity was most significantly increased when the Se fertilizer concentration was 5.0 mg/L.
