Abstract: An aquatic cultivation method for woody and drought-tolerant plants creates a symbiotic system of stable structure by steps of: (1) placing a seed in a pan for three to four weeks to grow an aquatic plant; (2) taking the aquatic plant out of the pan and removing dirt; (3) dipping the dirt-free aquatic plant into a beaker filled with a cultural liquid of somatotropic hormone for two to three hours; (4) taking out the aquatic plant and placing it into a container; (5) filling a substance into the container for securing the aquatic plant placed inside; (6) positioning the container on a water tank filled with water that the root of the aquatic plant can contact the water surface; and (7) completing cultivation when the root of the aquatic plant naturally extending into the water as adopted to an aquatic environment inside the water tank through time.
