Polygonatum cyrtonema seed breeding method capable of prolonging service life

The invention relates to the technical field of seed breeding, in particular to a polygonatum cyrtonema seed breeding method capable of prolonging the service life. The polygonatum cyrtonema seed breeding method comprises the following steps that S1, polygonatum cyrtonema seeds are preprocessed: A1, ripe polygonatum cyrtonema seeds are selected; A2, the polygonatum cyrtonema seeds stored in the previous step in the first ten-day period of April are taken out and are immersed in a seed treatment agent, wherein the seed treatment agent is prepared from, by weight, 0.05-2% of gibberellin, 0.02-3%of indoleacetic acid, 0.01-1% of naphthylacetic acid, 0.01-1% of 5-hydroxyl-IAA, 0.01-1% of indolebutyric acid, 0.01-2% of 6-benzylaminopurine, 0.01-2% of 6-furfurylaminopurine, 0.01-2% of zeatin andthe balance water ; A3, seed treatment is performed through cooperation of infrared light and ultrasonic waves; S3, sowing is performed. The polygonatum cyrtonema seeds are treated by adopting the seed treatment agent, growth
