The present invention provides a method for promoting the growth and preservation quality of Agaricus bisporus, and belongs to the technical field of cultivation and preservation of edible fungi. In the present invention, the methyl jasmonate solution is sprayed onto the surface of Agaricus bisporus at a concentration of 10-200 μmol/L when the Agaricus bisporus grows to the mushroom bud stage, which can accelerate the growth and development of the Agaricus bisporus, improve the post-harvest preservation quality of the Agaricus bisporus, and prolong the shelf life thereof, thereby improving the yield and commercial value of the Agaricus bisporus. The present invention provides a new method for increase in both production and income and post-harvest preservation of Agaricus bisporus, can be applied to large-scale industrial production of Agaricus bisporus, and thus has important economic benefits and application promotion value.
