Method for solving flowering asynchronism in peony crossbreeding

The invention discloses a method for solving flowering asynchronism in peony crossbreeding. The method comprises the following steps of: performing parent cultivation; performing outdoor vernalization; promoting cultivation in a greenhouse; comprehensively adjusting the flowering phase before initial blooming; and performing hybridization and subsequent management. The invention provides a methodfor preventing flowering asynchronism of parents in a peony crossbreeding process. The problems of different degrees of reduction of the pollen storage activity, reduction of pollen and stigma affinity, low peony hybridization success rate and the like due to adoption of storage pollen in the traditional technology are avoided; reduction of the pollen storage activity can be avoided; the fact thatparents with different flowering phases meet each other in flowering phase can be ensured; furthermore, the method is simple to operate and relatively low in cost; and peony crossbreeding work can becompleted conveniently and
