USE - Used as deadwood fermented organic fertilizer.    ADVANTAGE - The fertilizer increases soil fertility.    DETAILED DESCRIPTION - Deadwood fermented organic fertilizer comprises 10-30% rotten jujube bark, 15-30% rotten peach wood, 5-10% plant ash, 50-70% clay, 1-2% potassium chloride, 2-5% ammonium chloride, 5-10% urea, 4-10% attapulgite powder, 1-3% magnesium sulfate, proper amount of water and 5-10% auxiliary agent including 0.2-0.8 pts. methylene succinic acid, 3-5 pts. fly ash, 0.5-1 pts. borax, 4-6 pts. fresh Chinese honeylocust, 0.2-0.4 pts. potassium fulvate, 3-5 pts. fresh water plants, 15-20 pts. pond silt, 2-3 pts. limestone, 1.5-3 pts. fresh orange peel, 4-5 pts. cabbage and proper amount of water. The auxiliary agent is prepared by blending fresh Chinese honeylocust, fresh water plant, fresh orange peel and cabbage via mixer, adding pond silt and lime stone, stacking in dark humid environment for 5-7 days to rot, maintaining moisture by adding proper amount of water, adding coal ash, borax, methylene succinic acid and potassium fulvate, stirring uniformly, drying and crushing into powder. An INDEPENDENT CLAIM is also included for preparing organic fertilizer, comprising: (i) crushing the rotten jujube bark and rotten peach wood into small pieces, adding proper amount of water and soaking overnight for complete absorption of water, then filtering out excess water; (ii) adding plant ash, clay and attapulgite powder into resultant deadwood residue, mixing uniformly, sprinkling water to obtain 30-50% moisture, then stacking to ferment for 40-70 hours; (iii) adding potassium chloride, ammonium chloride, urea, magnesium sulfate and remaining auxiliary agent into fermented material and mixing uniformly; and (iv) adjusting the moisture content of crude product to less than 20%, pelletizing in a pelletizer, passing the qualified product into a wrapping machine for coating a film.
