Abstract

The invention provides a method for screening a water-soluble fertilizer containing a biostimulant, a quality control method of the water-soluble fertilizer containing the biostimulant, a method for detecting the water-soluble fertilizer containing the biostimulant and application of the water-soluble fertilizer containing the biostimulant. The method for screening the water-soluble fertilizer containing the biostimulant comprises the following steps: detecting a to-be-detected sample by adopting a high performance liquid chromatography to obtain a chromatogram; based on the chromatogram, a characteristic peak A, a characteristic peak B and a characteristic peak C are determined respectively, and the retention time of the characteristic peak A is 4.10-4.80 min; the retention time of the characteristic peak B is 7.00 to 7.70 min; the retention time of the characteristic peak C is 8.20 to 8.90 minutes. According to the screening method, the water-soluble fertilizer containing the biostimulant and high in stability can be obtained through accurate screening, and the method is high in repeatability, high in stability, easy and convenient to operate, low in cost and suitable for wide application.
