The invention discloses a building method for a frog and rice co-culture pond. The building method comprises the steps of A, the whole pond, wherein according to the size, the frog and rice pond is designed into a standard pond, and digging is conducted by using an excavator; B, a three-stage single ditch, wherein digging is longitudinally conducted in the middle of the frog and rice pond; C, a feeding table area, wherein the width of the feeding table area in the frog and rice pond is set as 1.5 meters, a reflective thin film is laid on all the feeding table area, and the periphery of the reflective thin film is pressed down and covered with soil; D, a rice field area, wherein the other portions, except for the portions in which the three-stage single ditch and the feeding table area arelocated, of the frog and rice pond are provided with the rice field area; E, water inlet and outlet pipes, wherein all the water inlet and outlet facility pipes are U-shaped pipes; F, an escape-proofnet, wherein the periphery of the frog and rice pond is covered with bamboo poles, and rana nigromaculata is prevented from jumping out of the pond; G, an anti-bird net, wherein one end of the escape-proof net is fixed to the outer periphery of the frog and rice pond, the middle of the escape-proof net is supported by using reinforcing steel bars, and birds are prevented from damaging rice and frogs. The method is easy to implement, the operation is simple, the ecological benefits are effectively improved, feeding management is facilitated, and the economic efficiency is improved. The problemsare solved that in an existing pond, water drainage is not smooth, the yield of the rana nigromaculata is low and the benefit is low.
