The invention discloses an efficient fertilizer with additional modified osmanthus fragrans essential oil and double-release effects for Chinese cabbage. The efficient fertilizer comprises, by weight, sodium alginate, nanometer kaolin, water-soluble polyethylene glycol, dietary fibers, cholesterol, threonine, potassium oxalate, disodium octoborate tetrahydrate, polyglutamic acid, yellow brown potassium humate, alkyl polyglucoside, lutein, humic acid, mycoprotein, aggregative active enzymes, photosynthetic bacteria, edible fungi residues, concha ostreae shell powder, sawdust, broken egg shells, modified tree ash, cortex cinnamomi oil, enzymes, copper-based nutrition protective agents, the osmanthus fragrans essential oil, an appropriate quantity of liquid anion water and an appropriate quantity of water. The efficient fertilizer has the advantages that the small-molecule osmanthus fragrans essential oil, the cortex cinnamomi oil and the lutein can assist in cultivating the Chinese cabbage with taste of osmanthus fragrans and are matched with nutrition liquid and main materials prepared from compost for preparing the efficient fertilizer, and accordingly the efficient fertilizer is nutritious and is high in efficiency.
