The invention discloses a seed treatment method for breaking the dormancy of seeds of a fruit tree and provides a whole set of seed treatment measures covering harvesting, screening, storage and pre-sowing treatment of the seeds. Compared with traditional deciduous fruit tree cultivation methods and seed dormancy breaking methods, the seed treatment method provided by the invention has the following advantages: the quality of the seeds of the fruit tree is substantially improved; budding time is greatly shortened; a budding rate is increased; an emergence rate is greatly increased; a grown fruit seedling has high quality; annual output of the fruit tree is increased; the disadvantages of long budding time and a low budding rate of traditional fruit tree seeds caused by improper dormancy breaking methods are overcome; troubles in plantation of the fruit tree are reduced; annual output of the fruit tree and fruit quality are substantially improved; and economic benefits are increased for orchard workers.
