The utility model discloses a nutrient solution supply device for crop water culture nutrition deficiency experiments. The nutrient solution supply device comprises a plurality of independent nutrient solution boxes. The bottom of each nutrient solution box is connected with a main solution pipe, a solution inlet valve is installed at the front end of each main solution pipe, a solution discharge valve is installed at the rear end of each main solution pipe, and a plurality of thin pipes are installed at the part between the solution inlet valve and the solution discharge valve of each main solution pipe. According to the nutrient solution supply device, the multiple independent nutrient solution boxes are arranged, and each nutrient solution box can be used for one experiment group of the nutrition deficiency experiments or a parallel experiment of a control group. Nutrient solutions in each nutrient solution box can flow to each repetition of parallel experiment groups through pipelines and the thin pipes. The management workload of the parallel experiment in the experiment process is lowered. Meanwhile, in the experiment process, the parallel experiments can be independent and will not disturb each other, experiment management is convenient, and the accuracy of experiment data can be improved conveniently.
