摘要

PROBLEM TO BE SOLVED: To provide a direct-cultivation method of rice capable of suppressing damage caused by shellfish without using any chemicals or any capture tools which destroy shellfish while suppressing growth of weeds in the case of cultivating rice by direct seeding.SOLUTION: The direct-cultivation method of rice comprises: a first step of sowing seed rice 6 in a paddy field in a water drop state by dropping water after puddling for averaging the surfaces of the paddy field; a second step of watering the paddy field after the first step to keep the watered state for a predetermined time period; a third step of dropping the water after the second step so that the water-dropped state is kept for a predetermined time period thereby to germinate and grow the seed rice 6; and a fourth step of watering the paddy field after the third step.
