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 i
