Vegetable waste organic fertilizer and preparation method thereof

Abstract

The invention relates to an organic fertilizer and a treatment technique of wastes in the planting industry, in particular to a vegetable waste organic fertilizer and a preparation method thereof. The preparation method adopts calcium cyanamide, natural zeolite and organic materials as additive materials, and adds the materials in vegetable wastes for piling up and fermentation so as to prepare the organic fertilizer; the method has simple process and low cost, and solves the problems of environmental pollution caused by the vegetable wastes and resource utilization. The components in percentage by weight of the organic fertilizer are: 73 to 84 percent of vegetable wastes, 10 to 20 percent of organic materials, 2 to 4 percent of calcium cyanamide and 3 to 5 percent of natural zeolite. Thepreparation method comprises the following steps: piling up the organic materials, the vegetable wastes, the calcium cyanamide and the natural zeolite in layers in proportion; scattering the organic materials on the outer layer; closing the organic materials by a plastic sheet to carry out fermentation for 7 to 10 days; carrying out mechanical or manual pile turning and then closing the organic materials by the plastic sheet to carry out fermentation for 7 to 10 days again; and obtaining the organic fertilizer after drying the materials in the sun. The vegetable waste organic fertilizer has reasonable formulation, good fertilizer reservation effect and easy implement, and is suitable to be used as fertilizer for producing green vegetables.
