Special liquid fertilizer prepared from yeast concentrated solution and used for beet

The invention provides a special beet liquid fertilizer prepared from a yeast concentrated solution, which is prepared by the following method: (1) adding a sulfuric acid solution into the yeast concentrated solution, and stirring for reaction to obtain a first reaction solution; (2) carrying out aeration treatment on the first reaction solution to obtain a second reaction solution; (3) standing the second reaction solution, and naturally precipitating the second reaction solution to obtain a precipitate and a suspension; and (4) dissolving the suspension, fulvic acid, urea, potassium sulfate, monoammonium phosphate, monopotassium phosphate, borax, chelated zinc, ammonium molybdate and a synergist in water to obtain the liquid fertilizer. The yeast concentrated solution is prepared into the special fertilizer suitable for beet growth, the problem that the yeast concentrated solution pollutes the water environment is solved, the requirement of beet for nutrients in each growth period can be met, and the nutrie
