NOVELTY - Base fertilizer and its preparation, are claimed. The base fertilizer comprises 29-31 wt.% human and animal excreta, 13-15 wt.% mixture of licorice, peach tree leaf and rapeseed, 5 wt.% wheat bran, 5 wt.% rapeseed cake, 8 wt.% lees, 12 wt.% river mud, 1 wt.% organic fertilizer fermentation agent, 1 wt.% organic fertilizer synergistic agent, 4 wt.% urea, 5 wt.% calcium superphosphate, 13 wt.% potassium sulfate, 0.4 wt.% magnesium sulfate, 0.3 wt.% zinc sulfate, 1 wt.% borax, 0.2 wt.% humic acid, and 0.1 wt.% amino acid.    USE - The base fertilizer is useful for activating soil, improving soil texture, inhibiting growth of soil pathogenic bacteria, and promoting growth of peach trees.    ADVANTAGE - The fertilizer is rich in organic matter, nitrogen, phosphorus, potassium and microelement, eliminates accumulation of toxin, and enhances nutrient absorption.    DETAILED DESCRIPTION - Base fertilizer and its preparation, are claimed. The base fertilizer comprises 29-31 wt.% human and animal excreta, 13-15 wt.% mixture of licorice, peach tree leaf and rapeseed, 5 wt.% wheat bran, 5 wt.% rapeseed cake, 8 wt.% lees, 12 wt.% river mud, 1 wt.% organic fertilizer fermentation agent, 1 wt.% organic fertilizer synergistic agent, 4 wt.% urea, 5 wt.% calcium superphosphate, 13 wt.% potassium sulfate, 0.4 wt.% magnesium sulfate, 0.3 wt.% zinc sulfate, 1 wt.% borax, 0.2 wt.% humic acid chelated iron, and 0.1 wt.% amino acid. The method involves (a) crushing human and animal excreta, mixture of licorice, peach tree leaf and rapeseed, wheat bran, rapeseed cake, lees and river mud in crusher, mixing the organic fertilizer fermenting agent with crushed product, adding water to mixture, and performing fermentation in autumn for 45-50 days to obtain organic fertilizer, (b) mixing organic fertilizer synergistic agent, urea, calcium superphosphate, potassium sulfate, magnesium sulfate, zinc sulfate, borax, humic acid and amino acid into a crusher to obtain powder-shaped organic fertilizer, and (c) mixing oraganic fertilizer of step (a) and powder-shaped organic fertilizer of step (b) to obtain product.
