摘要： A plant-microorganism combined method for phhytoremediation of organic contaminated soil; i.e., an ornamental plant (Impatiens balsamina L.)—microorganisms (petroleum hydrocarbon degrading mixed microbes) combined method for enhanced phytoremediation of petroleum contaminated soil is disclosed. The inoculated petroleum degrading mixed microbes can not only degrade contaminants in soil directly but also secretes chemical substances which are helpful to relieve the toxic effects on the Impatiens balsamina L. In return, the Impatiens balsamina L. releases photosynthesis products into the soil, so as to enhance microbial activity and quantity, and assist the microorganisms in degrading target contaminates more effectively and efficiently. Repeating the processes mentioned above is able to continuously reduce petroleum hydrocarbon contaminants in the soil until the residual content of contaminants meets the environmental safety standard.

摘要翻译： 有机污染土壤植物 - 微生物组合方法; （Impatiens balsamina L.） - 微生物（石油烃降解混合微生物）组合方法，用于增强石油污染土壤的植物修复。 接种的石油降解混合微生物不仅可以直接降解土壤中的污染物，而且可以分解有助于缓解凤仙花麻黄素L的毒性作用的化学物质。作为回报，Impatiens balsamina L.将光合作用产物释放到土壤中， 提高微生物活性和数量，并有助于微生物更有效和高效地降解目标污染物。 重复上述过程能够持续减少土壤中的石油烃污染物，直到污染物的残留物符合环境安全标准。
