A rice transplanting boat comprises a floating plate having a middle beam arranged longitudinally in the middle of the floating plate. Two corners of a front end of the floating plate have arc-shaped transitions extending toward two sides of the floating plate. The front end of the floating plate is bent upwards. A lower surface of the front end of the floating plate has a smooth arc-shaped surface. A lower surface of the middle beam protrudes out of the lower surface of the floating plate by 30-80 mm. In an operating mode, the front end of the floating plate is designed such that, when the floating plate moves, a moving resistance is significantly reduced, and the middle beam can descend to soil, and press to form a recess having a length of 30-80 mm in a gap between seedlings, achieving the goal of providing a ground level of the seedlings being higher than a ground level between the seedlings. The embodiment is utilized to effectively control levels of soil in a rice field, so as to control a water depth in a gap between seedlings, achieving the goals of weed inhibition, preventing roots of a rice crop from being damaged by pests, and increasing the yield.La présente invention concerne un bateau de transplantation de riz qui comprend une plaque flottante ayant une poutre centrale disposée longitudinalement au milieu de la plaque flottante. Deux coins dune extrémité avant de la plaque flottante comportent des transitions en forme darc sétendant vers deux côtés de la plaque flottante. Lextrémité avant de la plaque flottante est courbée vers le haut. Une surface inférieure de lextrémité avant de la plaque flottante comporte une surface en forme darc lisse. Une surface inférieure de la poutre centrale fait saillie hors de la surface inférieure de la plaque flottante sur 30 à 80 mm. Dans un mode de fonctionnement, lextrémité avant de la plaque flottante est conçue de telle sorte que, lorsque la plaque flottante se déplace, une résistance mobile soit réduite de façon s
