Provided is an accelerated breeding method for licorice seeds. The licorice fruit bearing period is shortened, and enough seeds are provided for artificially planting licorice. The accelerated breeding method for licorice seeds comprises the steps that triennial licorice principle roots are taken as licorice seedlings; a
land parcel with
irrigation arable soil or sandy soil is selected; the licorice seedlings are planted in a wide and narrow row spacing planting method; after the licorice seedlings are planted, a
drip irrigation zone is laid beside a licorice
seedling zone, and covered with a black mulching film; in the key breeding period of the licorice seedlings,
drip irrigation water is applied once every 20 days, the
drip irrigation amount is 20 m<3> each mu each time, and the number of total drip
irrigation times in a year is 8-10; after 80% licorice pods in the licorice seed land are mature, a
hay mower is used for harvesting at a time, and
threshing and airing are carried out in time. By means of the breeding method, the breeding period of licorice can be 2-3 years earlier, the seed yield is increased by 2 times or above, the worm damage rate of the seeds is controlled to be within 5% and is reduced by 15% or above compared with that of wild seeds, the seed
germination rate is greatly increased, and the seed
germination potential is greatly improved. Meanwhile, the pressure that licorice seeds rely on wild seeds for a long time can be relieved, the wild licorice genetic resource can be protected, and artificial destruction on the environment is controlled.
