The invention discloses an organic base fertilizer special for grapes and a production process thereof. The organic base fertilizer special for grapes contains the following components: cow and sheep droppings, biogas residues and biogas slurry, fulvic acid potassium, phosphoric acid, and organic calcium, magnesium, zinc and ferrum. The production process of the organic base fertilizer includes steps that: 1 potassium hydroxide is added into fulvic acid saturated solution to react to generate fulvic acid potassium; 2 calcium oxide, magnesium oxide, zinc oxide and iron sesquioxide are added into amino acid saturated solution to react to generate the organic calcium, magnesium, zinc and ferrum; and 3 cow and sheep droppings, biogas residues and biogas slurry, fulvic acid potassium, phosphoric acid, the organic calcium, magnesium, zinc, ferrum and biological species solution are mixed together in proportion, sufficiently stirred and stacked for fermentation and form the fertilizer after 20-30 days. The organic base fertilizer special for grapes can completely remove pollution of the fertilizer to the soil and grape fruits, reduces pest and disease damage, improves grape yield and quality, improves the soil, avoids alkalization and salination, and enables the grape fruits to be stored for a long time.
