Germination-accelerating and yield-increasing method for winter potato seed tubers

The invention belongs to the technical field of potato cultivation and discloses a germination-accelerating and yield-increasing method for winter potato seed tubers. The method comprises the steps ofbreaking dormancy, and cutting a wound which is 1-2 cm in depth and 5-10 cm in length in each seed tuber on a sunny day; storing the seed tubers and accelerating germination; preferentially plantingterminal buds, namely when terminal buds grow to 0.5 cm, cutting out the seed tubers with the terminal buds and ensuring that each cut seed tuber has one bud, airing the remaining parts of the seed tubers in a cool dry place for 2-3 hours and putting back the remaining parts for accelerating germination again after the wounds are dry; planting lateral buds for ending, namely ensuring that each seed tuber has 1-2 buds according to the strong bud situation while cutting out the seed tubers with the lateral buds; and carrying out germination accelerating and batch planting through the mode of preferentially planting the t
