The invention provides a cultivation tank capable of high-efficiently and accurately regulating nutrient solution. The cultivation tank is a cuboid tank, the upper edges of two long side faces are inwards coiled to form grooves which reserve gaps with the long side faces and are opened upwards, the tops of the grooves are not closed, namely one side of the cross section of the inward coiling part is G-shape which is downwards opened, and the other side is a left and right mirror image of the G-shape which is downwards opened; two formed grooves are a liquid feeding groove and a liquid discharging groove, one short side face of the tank is provided with a liquid inlet and a liquid outlet which are respectively connected with a liquid feeding pipe and a liquid discharging pipe, the liquid inlet and the liquid outlet are respectively aligned to the liquid feeding groove and the liquid discharging groove, and the liquid inlet is higher than the liquid outlet slightly. The invention further provides a using method for the cultivation tank capable of high-efficiently and accurately regulating nutrient solution. The cultivation tank is used so that the circulation process of the nutrient solution in the cultivation tank is changed from the original longitudinal flow along the length to the transverse flow along the width, the flow distance is greatly shortened, the whole cultivation tank is injected with the nutrient solution at the same time along the edges of the liquid discharging groove in the manner of water screen, and the nutrient solution can be uniformly replaced during the short time.
