NOVELTY - Preparation of a functional organic compound fertilizer includes preparing a seed culture medium by mixing 0.2 wt.% ammonium sulfate, 0.3 wt.% potassium dihydrogen phosphate, 1 wt.% industrial whey powder, 1.2 wt.% industrial peptone, 4 wt.% soybean powder, 1.5 wt.% industrial glucose, 0.5 wt.% yeast extract powder, 0.5 wt.% industrial sodium chloride, 0.1 wt.% magnesium sulfate, 0.2 wt.% lactose, 0.3 wt.% oligochitosan, and 89.5 wt.% water, inoculating at 30 plus minus 1 degrees C with strain culture medium including Serratia marcescens (ACCC 10119), fermenting, and culturing for 30 hours.    USE - Method for the preparation of a functional organic compound fertilizer (claimed).    ADVANTAGE - The fertilizer has improved shelf life and viable bacteria of survival time, and improves germination percentage and crop stress resistance.    DETAILED DESCRIPTION - Preparation of a functional organic compound fertilizer comprises preparing 200 mL strain culture medium comprising mixing 2 wt.% industrial whey powder, 0.4 wt.% industrial lactate, 0.1 wt.% industrial anhydrous sodium acetate, 1 wt.% industrial peptone, 3 wt.% soybean powder, 1.5 wt.% industrial glucose, 0.5 wt.% yeast extract powder, and 91.5 wt.% water at a natural pH, adding 0.1 mL Lactobacillus buchneri (CICC 6004), adding 0.1 mLBacillus cereus(ACCC10117), placing in a sealed flask, shaking at 140 revolutions/minute (rpm), culturing at 37 plus minus 1 degrees C for 6 hours, stopping shaking, adding 0.1 mL Saccharomyces cerevisiae (CICC1905) and S. marcescens (ACCC 10119), placing in a sealed bottle, shaking at 140 rpm, and culturing at 32 plus minus 1 degrees C for 10 hours; and preparing a seed culture medium by mixing 0.2 wt.% ammonium sulfate, 0.3 wt.% potassium dihydrogen phosphate, 1 wt.% industrial whey powder, 0.5 wt.% industrial lactate, 0.2 wt.% industrial anhydrous sodium acetate, 1.2 wt.% industrial peptone, 4 wt.% soybean powder, 1.5 wt.% industrial glucose, 0.5 wt.% yeast extract powder, 0.5 wt.% industrial sodium chloride, 0.1 wt.% magnesium sulfate, 0.2 wt.% lactose, 0.3 wt.% oligochitosan, and 89.5 wt.% water, inoculating at 30 plus minus 1 degrees C with strain culture medium under aseptic condition, ventilating and fermenting, and stirring at 140 rpm, culturing for 30 hours.
