The invention discloses a paddy rice planting method with easy irrigation. The method comprises following steps: reclaiming, terrace field setting, first ridge stacking, water ditch setting, planting land setting, second ridge stacking, first water flowing opening setting and second water flowing opening setting; land preparing, opening the second water flowing opening, soaking the planting land, covering with decomposed mixed material and comprehensive soil turning, and then covering with mixed soil material which prepared by mixing dry soil, pine needle soil, vinasse, pond sludge, sawdust, urea, boric acid and probiotics liquid; seed soaking and germination accelerating; seedling growing; seedling transplanting; field managing and harvesting. By means of the installation of the water ditch, the first water flowing opening and the second water flowing opening, the first water flowing opening and the second water flowing opening can be opened selectively according to different amount of water that is needed in different processes during paddy rice planting; superfluous water is stored in the water ditch and is used for irrigating a next corresponding planting land under the action of the self gravity of the water ditch, which saves labor and material resource; the use of the decomposed mixed material and the mixed soil material lay good foundation for the growth of paddy rice.
