Abstract: In simulated experiment of arid sandland environment, the seeds of Caragana intermedia and Artemisia schrenk Songarica were treated by different electric strength and used to test the effects of electric field on the drought resistance of the seeds in the germinating stage. The results show that the electric field treatment can decrease the negative impact from drought degree aggravating. Different electric field strength has different effects on the soil drought stress adaptability of the seeds in the germinating stage and biomass. The electric field treatment can increase seed germinating energy, germination rate, and the biomass wet weight and dry weight. All these changes were favorable for reducing the damage and strengthening the adaptability of drought stress of the seeds.
