Simple and efficient treatment method of abscisic acid crude product mother liquor

The invention discloses a simple and efficient treatment method for an abscisic acid crude product mother liquor. The treatment method is characterized by comprising the following steps: adjusting the pH value of the abscisic acid crude product mother liquor: adjusting the pH value of the abscisic acid crude product mother liquor by using liquid caustic soda; stirring and filtering: uniformly stirring and mixing the mother liquor with adjusted pH, and filtering through a filter bag; the filtered crude product mother liquor is sampled and detected, the titer of the crude product mother liquor is detected, and the titer is generally 2000-3000 ug/ml (the titer is expressed by u, and the unit is ug/ml); and calculating the required concentration or dilution multiple: calculating the multiple of the mother liquor needing to be concentrated or diluted according to the concentration of the preparation needing to be prepared according to a calculation formula. The method is simple and convenient to operate, easy to i
