NOVELTY - Production of liquid-state organic fertilizer includes closed fermenting manure solution generated by dehydrating fresh chicken manure for 6-10 days at 26-30 degrees C in a biological fermentation tank; adding sodium nitrate powder and plant growing agent to the tank; standing for 1-2 hours; filtering to obtain filter liquor, i.e. liquid-state organic fertilizer; and taking the filter residue as raw material for producing solid-state organic fertilizer.    USE - Production of liquid-state organic fertilizer (claimed).    ADVANTAGE - The method enables the manure solution generated by dehydrating fresh chicken manure to be effectively utilized so as to reduce environment pollution and increase economic benefit.    DETAILED DESCRIPTION - Production of liquid-state organic fertilizer comprises:    (A) dehydrating fresh chicken manure by collecting fresh chicken manure on the day it is generated in chicken farm; conveying to an inlet of auger conveying machine; injecting water, which is 20-30% of fresh chicken manure via the inlet; diluting the fresh chicken manure; connecting the outlet of auger conveying machine with the inlet of chicken manure dehydrating machine; conveying the fresh chicken manure diluted from the outlet of the auger conveying machine to the chicken manure dehydrating machine for dehydrating until water content is 50-55%; using dehydrated solid manure residues to produce solid-state organic fertilizer; and injecting the manure solution to water storage pond; and    (B) pumping the manure solution in water storage pond to a biological fermentation tank; adding brown sugar (5-10 wt.% of the total weight of manure solution), anaerobic fermentation bactericide ( greater than or equal to 2x 108 bacteria/ml) (2-5 wt.%), urea (3-6 wt.%), calcium superphosphate (10-15 wt.%), and soybean cake pulp (6-10 wt.%); uniformly stirring; closed fermenting for 6-10 days at 26-30 degrees C; adding sodium nitrate powder and plant growing agent (0.06-0.08 wt.% based on the total weight of liquid in the tank) to the tank; standing for 1-2 hours; filtering to obtain filter liquor, i.e. liquid-state organic fertilizer; and taking the filter residue as raw material for producing solid-state organic fertilizer.
