The invention discloses sphere-shaped 
fertilizer. The 
fertilizer comprises, by weight, 80-100 parts of mixtures prepared by ground 
phosphate rock, thoroughly-decomposed 
chicken manure and 
plant ash according to the 
mass ratio of 1:2:4, 40-50 parts of mixtures prepared by 
vinasse and 
sugar residues according to the 
mass ratio of 3:1, 30-40 parts of 
calcium superphosphate, 20-40 parts of spirulina 
powder, 30-50 parts of mixtures prepared by grass-
hay powder and pepper dregs according to the 
mass ratio of 7:1, 20-40 parts of 
animal fat, and 10-30 parts of mixtures prepared by a 
cinnamaldehyde solution, 
salvia miltiorrhiza 
powder and 
glutamic acid according to the 
mass ratio of 5:2:1. Preparation of the 
fertilizer is simple, fertilizer efficiency time is long, fertilization is convenient and fast, specifically, the raw materials are placed into a heating reaction kettle, fused, then poured into a mold, and released from the mold after being cooled to form the sphere-shaped fertilizer, the 
diameter of the fertilizer is 5-8 cm, and only one piece of the fertilizer is placed; moreover, as the 
diameter of the fertilizer is large, and the fertilizer is coagulated into a lump, time for slow release is greatly prolonged, compared with fertilizer in a 
small particle shape in the past, the fertilizer efficiency is improved by 75-85%, the fertilization speed is increased by 65-80%, and the fertilization cost of farmers and the manufacturing cost of manufacturers are greatly reduced.
