The invention discloses an efficient controlled release fertilizer favorably improving taste and freshness of ivy mosses. The fertilizer comprises the following components in parts by weight: oyster shells, polylactic acid, expanded graphite, thermally activated nano chernozem, pinecones, pomegranate barks, mosses, sugarcane ash, a soil beneficial microbial inoculant, bacitracin zinc, phytase, amino acid, ground calcium ammonium sulfate, boric acid, sodium selenite, chelated iron, potassium fulvate, lysine, a proper amount of hydrogen peroxide, a proper amount of ammonia water, a proper amount of water and the like. The coated controlled release fertilizer is prepared by using the pinecones, the pomegranate barks, the mosses and the sugarcane ash which are matched with nutritional substances through fermentation. The fertilizer is rich in nutrient elements such as fermented small molecular organic matters, calcium, iron, selenium and zinc, is abundant in nutrient and convenient for plants to absorb and utilize, so that the taste and freshness of the ivy mosses can be enhanced; by adopting the coating layer which can supply oxygen and dynamically adjust the porosity, the fertilizer efficiency time is long, organic matter nutrients can be released for a long time, efficient cultivation of the ivy mosses can be realized, and the fertilizer can be widely applied and popularized.
