The invention relates to the field of controlled release fertilizer technology, and in particular to a special film-coated controlled release calcium fertilizer for peanut, comprising a three-layer structure, wherein raw materials in an inner layer comprise calcium nitrate, humic acid, seaweed extract and adhesive; raw materials in an intermediate layer comprise calcium nitrate, urea formaldehyde powder and chitosan oligosaccharide; and raw materials in an outer layer comprise urea formaldehyde powder and fermented livestock and poultry manure. The special controlled release calcium fertilizer for peanut according to the invention releases Ca since the pod-bearing stage after the basal application, not only avoids Ca inhibition of K absorption in the early growth stage of peanut, but also reduces the workload, increases the pod yield, and improves the seed kernel quality The coating film is a biodegradable film, releases calcium since about 50 days after application into soil. The nutrient release curve compl
