The invention discloses an artificial supplementary pollination method in hybrid rape seed production, which comprises the following steps: planting male parents and female parents of hybrid rape in rows according to a ratio of 1: 2, respectively inclining two rows of female parent plants to adjacent male parent row plants in an initial flowering stage, so that the two rows of female parent row plants clamp one row of male parent row plants and are fixed together; and after maturation, harvesting the male parent and the female parent in rows. According to the method, the breeding efficiency of the brassica napus germplasm sterile three-line is improved, the plant height of the male parent and the female parent does not need to be changed through breeding, the breeding period is shortened, and the breeding progress is accelerated. The method is small in workload, manpower and material resource investment is reduced, the seed production cost of the hybrid rape can be reduced, and therefore the production benefi
