Problems solved by technology

[0003] However, ginkgo trees grow slowly, and ginkgo seeds have dormancy characteristics. When the seeds mature, the embryos have not yet fully differentiated, so the germination rate is very low, only about 40%.

Abstract

The present invention provides a ginkgo biloba seed germination method, comprising the following steps of: sterilizing seeds by using a sodium hypochlorite solution; soaking the seeds by using a gibberellin solution; after using a rice bran pile to produce seven windrows and meanwhile performing fermenting for one day, burying the ginkgo biloba seeds into a first windrow and keeping the seeds therein for one day, then taking out immediately and burying the seeds into a next windrow and keeping the seeds therein for one day, until the seeds are kept in a seventh windrow for one day, and taking out the ginkgo biloba seeds; taking vermiculite, wetting the vermiculite by using a gibberellin solution, and putting the vermiculite into a plastic bag, also putting the ginkgo biloba seeds into the plastic bag, kneading the plastic bag for 5-10 minutes every 2-3 hours, and taking out the ginkgo biloba seeds after kneading is performed for 5-8 times; and putting the ginkgo biloba seeds into a pressure tank, vacuuming the pressure tank by using a suction pump, keeping the conditioin for 1-2 minutes, and then injecting air, performing vacuuming and air injecting operations once every day, and taking out the ginkgo biloba seeds after 3-5 days. The ginkgo biloba seed germination method can effectively break the dormancy of the ginkgo biloba seeds, and improve the germination rate of the ginkgo biloba seeds.

Description

technical field [0001] The invention relates to the field of ginkgo cultivation. More specifically, the present invention relates to a method for accelerating germination of ginkgo seeds. Background technique [0002] Ginkgo tree, also known as ginkgo tree, is the oldest gymnosperm left over from the Quaternary glacial movement and one of the most precious tree species in the world, so it is regarded as a "living fossil" in the plant kingdom. And the ginkgo tree has good appreciation, economy and medicinal value. [0003] But ginkgo tree grows slowly, and ginkgo seed has dormancy characteristic, and when seed matures, the embryo has not yet fully differentiated, so directly sow with ginkgo seed, and the germination rate is very low, only about 40%. Therefore, urgently need to design a kind of dormancy of breaking ginkgo seed, impel ginkgo seed to germinate, improve the method for ginkgo seed germination rate. Contents of the invention [0004] An object of the present i...
