Abstract:: Taking Rhodiola algida var. tangutica as material, using single factor randomized block，the effects of urea solution with different conlentrations on seed germination of the seeds of Rhodiola algida var.tangutica were studied，and germination rate，germination energy and germination index were determined.The results showed that urea solution had significant effects on seed germination of Rhodiola algida var.tangutica,when nitrogen content was 0.3 g/L，urea solution had improved respectively their seed germination rate，germination energy，germination index and other indicators.When nitrogen content was increased to more than 0.3 g/L，seed germination was obviously inhaibited.
