The invention discloses a method of germinating citrus seeds, comprising the steps of selecting citrus seeds as a raw material, soaking in warm water at 35-40 DEG C, placing in a germinating box again, turning on electrode plates to subject the citrus seeds in the germinating box to primary germination, soaking in warm water in a container again while adding a nutrient solution into the container, then adding a germinating liquid to the germinating box, turning on the electrode plates to subject the citrus seeds in the germinating box to primary germination, sowing the citrus seeds in a nursery field earthed to 5-8 cm in thickness, and growing seedlings. At the premise of ensuring required nutrition for the growth of citrus, deliciousness of citrus fruits is ensured, low-cost large-scale quick propagation of citrus seedlings is achieved, growing speed is higher, survival rate and planting effect of citrus are effectively improved, and the method is simple and reliable.
