The invention relates to the technical field of
plant breeding and production, in particular to a breeding method for seedlings of Jujun flowers without pericarp and pulp, which comprises the following steps: S1, picking
infructescence; s2, the fruits are picked off from
infructescence, mixed with
river sand or
vermiculite and then soaked with a treatment solution, a roller device is filled with the soaked fruits, and a mixture is obtained through treatment; s3, uniformly
sowing the mixture treated in the step S2 on a
seedling raising tray; s4, covering with a film, and culturing until seedlings are formed; s5,
transplanting the seedlings with the
plant height exceeding 4 cm into flowerpots or
seedling raising bags; and S6, tending. The invention further provides a roller device for
processing the fruits by simulating the strategy that the birds eat the fruits to spread the seeds. By means of the roller device and the propagation method, manual separation of seeds, pulp, peel and the like is not needed, and the labor cost can be saved; and the
germination rate of the seeds of the
juniper blossom can be effectively increased to 60-70%, the
seedling yield can be effectively increased to 40-50%, the seedling raising period of the seedlings of the
juniper blossom can be shortened, and the flowering seedlings of the
juniper blossom can be obtained in September to December.
