This project will be carried out to improve energy crops Sunflower Research and Analysis of heavy metals in the soil. Explore the integration of plant growth hormones and chelating vegetation restoration soils contaminated with heavy metals and further assessment of energy crops Sunflower heavy-metal contamination of soil remediation operation -cum- related environmental factors intended . By experiment and explore plant growth hormones and heavy metals on the growth scenario explants ( explants morphological analysis ). The experiment’s results indicate that GA3 can increase the growth rate of the plant：The average increment of the heavy-metal-added-only group is 18.89 cm; the average increment of the GA3-added group is 19.5 cm; the average increment of the EDDS-added group is 19.0 cm; the average increment of the GA3+EDDS-added group is 20.4 cm. The experiment’s results indicate that EDDS can increase the solubility of heavy metals in soil and enchance phytoextraction ：the plant accumulates a concentration of the heavy-metal-added-only group is 7.635±0.14 mg/kg; the plant accumulates a concentration of the GA3-added group is 10.522±0.212 mg/kg; the plant accumulates a concentration of the EDDS-added group is 17.037±0.637 mg/kg; the plant accumulates a concentration of the GA3+EDDS-added group is 16.216±1.503 mg/kg. Compared with the conventional methods of phytoremediation, these integrated measures can actually spur the growth of plants .
