In this experiment, the seed from Haibei of Qinghai was taken as the research material, hydro-priming pretreatment technology of plant seeds was adopted to study the effects of hydro-priming treatment of different durations（10, 20, 30, 40 and 50 min） on seed germination and seedling growth. The results showed that seed germination rate, germination potential, germination index, vigor index, seedling embryo length, radicle length and dry matter quality were different in different time treatment, hydro-priming time of 20～30 min was significantly higher than other treatments（P＜0.05）, hydro-priming treatment for 20～30 min was the optimal time. This study provides theoretical basis and technical support for solving the problems of low seed germination rate and uneven seedling growth in actual production.
