【Abstract】 On the basis of analyzing main elemental composition of the retorted oil shale in Maoming, Guangdong Province, the experiments of applying calcium oxide and calcium superphosphate for the remediation of the matrix as well as the growing plants in pots are conducted. The retorted oil shale contains certain level of major and minor nutritional elements. Due to the effects of elemental interactions, Ca- contained ameliorators possess the functions of adjusting acidity, promoting the availability of phosphorus and potassium, and inhibiting the uptake of aluminum and cadmium by plants. The plant is well-developed. The results can serve as a scientific basis for turning the industrial solid waste into resource through agricultural utilization.更多还原
