Cercidiphyllum japonicum sowing and seedling growing technology

The invention discloses a cercidiphyllum japonicum sowing and seedling growing technology. The technology comprises the following steps of seed collection and storage, seed treatment, nursery land and seedbed preparation, sowing, seedling management, seedling division and protection and nursery-out for afforestation when the ground diameter of one-year seedlings can reach 0.5 cm or above and the height of the seedlings reach 50 cm or above. According to the biological characteristics and ecological habits of cercidiphyllum japonicum, the ecological environment where cercidiphyllum japonicum grows is simulated, seeds are finely selected, soil is improved, sowing is conducted finely, protection is conducted carefully, the temperature, humidity, illumination and other natural factors required for growth of the seedlings are adjusted in real time, the sowing and seedling growing technology with cercidiphyllum japonicum seed germination accelerating and sprout seedling transplanting being the core and an earthing
