The invention provides a method for improving the germination rate of picea mongolicas seeds by using gibberellin. The method comprises the following steps: firstly, soaking aseptic picea mongolicas seeds by using 0.3 to 0.8mg/L of gibberellin solution for 20 to 28 hours to obtain pretreated seeds; secondly, mixing the pretreated seeds obtained in the first step with pretreated river sand according to the volume ratio of 1 to (2 to 5) to obtain a germination accelerating system; and stacking the germination accelerating system under the condition of 10 to 15 DEG C and accelerating germinationfor 7 to 10 days to obtain emerge-geminating seeds. The method disclosed by the invention has the advantages that the seed dormancy can be effectively broken and the germination rate of the seeds is improved; and in addition, seedlings orderly emerge, and the germination rate of the picea mongolicas can reach 90 percent or above. 本发明提供了种使用赤霉素提高沙地云杉种子萌发率的方法，包括以下步骤：1)将无菌沙地云杉种子使用0.3～0.8mg/L的赤霉素溶液浸泡20～28h获得预处理种子；2)将步骤1)所述预处理种
