Method of adjusting flowering phase of potted flower

The invention discloses a method of adjusting a flowering phase of a potted flower. The method includes 1, sterilizing the ground; 2, stacking sawdust on the ground, and building a block wall around the sawdust; 3, placing the potted flower in the sawdust, and controlling the water content of the sawdust to 30%-40%; 4, controlling the environmental air temperature at 22 DEG C to 30 DEG C through an air heater in a greenhouse; utilizing the sawdust to ferment and generate heat; controlling moisture content of the sawdust and the temperature of the sawdust at 18 DEG C to 25 DEG C, and accordingly increasing the temperature of cultivation substrate of the potted flower and maintaining the temperature for 20 to 30 days; 5, removing the flower after flowering. The air heater and the heat generated by the sawdust fermentation are utilized to control the environmental air temperature and the temperature of the cultivation substrate of the potted flower in a combined manner, so that the flowering phase of the potted
