Method for verifying effect of GHH on absorption of EE2 and Cd by ryegrass

The invention discloses a method for verifying the effect of GHH on the absorption of EE2 and Cd by ryegrass. With the verification method of the invention adopted, it can be verified that the ryegrass and GHH can be combined to restore EE2-Cd complex contaminated soil; the GHH of which the preservation number is CCTCC NO: M2017539 belongs to the hyphomicrobium and is named as Hyphomicrobium sp. GHH; with the GHH inoculated, the growth of plants can be significantly promoted, the efficiency of the extraction of the EE2 and Cd by the ryegrass can be improved; with the ryegrass planted on soil,and the GHH inoculated, urease activity and the carbon content of microbial biomass can be promoted, and soil environment can be improved. 本发明公开了一种GHH对黑麦草吸收EE2与Cd的作用及验证方法，运用本发明的验证方法验证得到黑麦草联合GHH能够修复EE2-Cd复合污染土壤；GHH为保藏编号CCTCC NO：M2017539的生丝微菌属，命名为Hyphomicrobium sp.GHH；接种GHH显著促进了植物的生长，提高了黑麦草对EE2和Cd的提取效率；在土壤上种植黑麦草并接种GHH对脲酶活性和微生物量碳含量具有促进作用，能够改善土壤环境。
