NOVELTY - Insect pest resistant liquid microbial fertilizer comprises 10-20 pts. wt. Bacillus megaterium, 10-30 pts. wt. Pseudomonas fluorescens, 10-30 pts. wt. potassium proteolytic bacteria, 10-30 pts. wt. Azotobacter, 10-30 pts. wt. B.amyloliquefaciens, 10-30 pts. wt. B.subtilis, 10-20 pts. wt. B.thuringiensis and 10-30 pts. wt. Saccharopolyspora spinosa.    USE - Insect pest-resistant liquid microbial fertilizer (claimed).    ADVANTAGE - The preparation method of the microbial liquid fertilizer is simple and production cost of the fertilizer is reduced by 3-5 times. The added Azotobacter has no host specificity and has good nitrogen fixation effect. The pleocidin generated in high amount by the S.spinosa provides highly efficient pest-resistant effect to the plants, and yield of the microorganisms in the fermentation medium reaches up to 1000 mg/l.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the above-mentioned liquid microbial fertilizer, which involves adding and mixing seed liquids of the above-mentioned microorganisms except the Azotobacter and S.spinosa in predetermined weight proportions, inoculating 5-10% mixed seed liquid inoculum in first fermentation culture medium inside fermentation tank, performing first fermentation at 300 revolutions per minute (rpm) and 37 degrees C for 21 hours, inoculating 5-10% Azotobacter seed liquid inoculum in second fermentation medium, performing second fermentation at 200 rpm and 28 degrees C, further inoculating 5-10% S.spinosa seed liquid inoculum in third fermentation culture medium, performing third fermentation at 240 rpm and 29 degrees C for 7 days, adding and mixing obtained fermented liquid concentrate obtained after the first and second fermentation processes in a mass ratio of 3:1-9 to obtain mixed culture liquid, adding and mixing the mixed culture liquid and first storage culture medium in a mass ratio of 1:1 to obtain A-type liquid fertilizer, and adding and mixing fermented liquid concentrate obtained after the third fermentation process and second storage culture medium in a mass ratio of 1:2-4 to obtain B-type liquid fertilizer.
