NOVELTY - A composite fertilizer comprises 42-57 pts. wt. earthworm, 24-36 pts. wt. molasses, 5-10 pts. wt. agar, 6-12 pts. wt. shaddock fruit pulp, 4-6 pts. wt. urea, 9-16 pts. wt. phosphate, 5-8 pts. wt. humic acid, 10-14 pts. wt. nano-graphene, 18-25 pts. wt. plant ash, 6-10 pts. wt. chitin, 8-14 pts. wt. rice bran and 8-12 pts. wt. pagoda tree flower. USE - Composite fertilizer used for planting cucumber (claimed). ADVANTAGE - The fertilizer has slow release function and increases yield of cucumber. The fertilizer has slow release function and increases yield of cucumber and has synergistic effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the fertilizer comprising pressing shaddock fruit pulp into juice, enzymolysis at 33-42 degrees C under pH 5-6, inactivating enzyme, filtering enzymolysis product, centrifuging and separating to obtain grapefruit enzymolysis liquid; crushing pagoda tree flower to 40-60 meshes, mixing crushed product with 45-66% ethanol aqueous solution, soaking for 3-5 hours, centrifuging, filtering supernatant to obtain pagoda tree flower extract; mixing earthworm manure, molasses, urea, humic acid, sodium dihydrogen phosphate, shaddock enzymolysis liquid, chitin and rice bran, adding water, adjusting mass percentage of water to 60-72%, adding complex bacteria 0.2-0.4% of total weight of material, composting and fermenting for 18-25 days and turning once per 16-20 hours to obtain fermented product; crushing agar to 120-150 meshes, adding pagoda tree flower, ultrasonic oscillating to agar suspension; and mixing nanographene, fermented products, agar suspension and plant ash in high-speed and drying at 35-48 degrees C to obtain finished product.
