Abstract: The invention relates to the technical field of agricultural planting, in particular to a controlled-release bacterial fertilizer for peanuts and a preparation method of the special controlled-release bacterial fertilizer. The special controlled-release bacterial fertilizer is composed of an inner layer and an outer layer; after the outer layer is released completely, the inner-layer network structure gradually absorbs water and preserves moisture, and has good slow release and controlled release properties, thereby achieving the gradual release of the inner layer, high fertilizer utilization rate, exerting the efficacy of the microbial agent and facilitating the large-area promotion.

Abstract: A special film-coated controlled release calcium fertilizer for peanut includes a three-layer structure. Raw materials in an inner layer include calcium nitrate, humic acid, seaweed extract and adhesive. Raw materials in an intermediate layer include calcium nitrate, urea formaldehyde powder and chitosan oligosaccharide. Raw materials in an outer layer include urea formaldehyde powder and fermented livestock and poultry manure. The special controlled release calcium fertilizer for peanut releases Ca since the pod-bearing stage after the basal application. The coating film is a biodegradable film, releases calcium since about 50 days after application into soil.
