Abstract

The invention discloses a fertilizer special for maintaining lawns and a preparation method thereof. The method comprises the following steps: weighing, mixing and stirring citric acid, zinc sulphate powder, copper sulphate powder, manganese sulphate powder, ferrous sulphate powder, borax powder, ammonium molybdate and water at a temperature of 80-90 DEG C for 40-60 minutes to prepare trace element chelate fertilizer liquid; weighing, mixing and stirring polyvinyl alcohol, cornstarch and dicyandiamide powder at a reaction temperature of 80-90 DEG C for 40-60 minutes to prepare bonding liquid;uniformly mixing the trace element chelate fertilizer liquid and the bonding liquid according to a mass ratio of 1:4 for spare; weighing, drying, crushing and screening pyrobituminous shale residue, furfural residue, calcium carbonate, magnesium sulphate, urea, diammonium phosphate and potassium sulphate by a screen of 100-120 meshes; uniformly mixing; adding the mixture to a pelletizer; and spraying the mixed liquid to granulate so as to obtain the fertilizer special for maintaining lawns. The invention has the advantages of enough nutrients, good slow release, and the like, prolongs the nutrient-supplying time and protects the biological environment.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to a special fertilizer for lawn maintenance and a preparation method thereof. 2. Background technology [0002] At present, lawn has become an important symbol of urban greening, and the original soil in many cities is covered by lawn grass. Under normal circumstances, turfgrass needs to maintain fixed growth for many years. In addition to applying base fertilizer when building a lawn, topdressing is also required during the growing season of turfgrass. Since turfgrass needs to be trimmed frequently, a large amount of fertilizer is required. The existing fertilizers applied are not sufficient in nutrients and have poor slow-release properties, making it difficult to meet the long-term growth needs of turfgrass. [0003] Oil shale is a kind of sedimentary rock containing organic matter. The proven resource in my country is 2.4 billion tons. As the world...
