摘　　要：针对志丹油田附近受石油污染的土壤,利用植物-微生物联合处理,促进志丹油田附近石油污染土壤修复。根据植物种子对石油污染土壤的耐受能力、植物形态生理指标以及植物对土壤石油烃的降解能力,筛选获得黑麦草(63.28%)和紫花苜蓿(59.31%)两株对石油污染土壤具有良好修复能力的植物。从植物根际土壤筛选获得一种对石油污染土壤具有高效修复能力的微生物菌剂ZD。利用黑麦草和紫花苜蓿与复合微生物菌剂ZD联合对石油污染土壤进行修复,发现当微生物菌剂ZD接种量为1.25%时,植物-微生物联合修复石油污染土壤获得较好的效果(78.28%)。该研究从石油污染土壤中获得植物以及微生物菌剂,然后将其合理处理后,再次用于石油污染土壤的修复,以“取之于此,用之于此”的理念,成功实现石油污染土壤高效修复。The present study was conducted to promote the remediation of oil-contaminated soils near the Zhidan oilfield using combined plant-microbe treatments.Two plants,ryegrass(63.28%)and alfalfa(59.31%),were selected for their significant remediation capabilities in petroleum-contaminated soil based on their seed tolerance to petroleum-contaminated soil,morpho-physiological indices,and their ability to degrade soil petroleum hydrocarbons.A microbial fungicide,ZD,with efficient remediation capabilities for petroleum-contaminated soil,was isolated from the rhizosphere of ryegrass and alfalfa.The use of ryegrass and alfalfa in conjunction with the composite microbial fungicide ZD for the remediation of petroleum-contaminated soil revealed that an inoculum of 1.25%of microbial fungicide ZD yielded a notable effectiveness(78.28%)in the combined plant-microbe remediation of petroleum-contaminated soil.This study successfully obtained plants and microbial agents from petroleum-contaminated soil,and after proper treatment,reused them for the efficient remediation of petroleum-contaminated soil,aligning with the principle of utilizing local resources for remediation purposes,as exemplified by the concept“what is taken from here,is used in here.”
