Abstract

The invention relates to a composite organic fertilizer. The compound organic fertilizer is granular, and is prepared from the following components by weight: 55%-65% of cow dung powder, 15%-25% of vermicompost, 10-20% of organic materials, 1-3% of natural zeolite and 2%-4% of a binder. The compound organic fertilizer produced by the method uses cattle manure as the main raw material, and conducts dehydration, drying and pulverizing to prepare a cow dung dry powder; and then according to the optimization ratio, vermicompost, organic materials, natural zeolite and binder are used to produce the organic fertilizer. The production process is simple and low in cost. The invention solves the problem of manure treatment in large-scale cattle farms, but also gets clean organic fertilizer, so as to achieve the recycling of cow dung, reduce cow manure treatment the cost and greatly improve the economic efficiency of enterprises. The compound organic fertilizer can be widely used in farmland, orchards and vegetable fields, and provides strong guarantee in the aspect of fertilizer for the development of green and low-carbon agriculture.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and in particular relates to a compound organic fertilizer and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the demand for dairy products and beef has increased, and the scale of cattle farms has also begun to change from the past grazing model to the current centralized feeding model. With the increasing intensification of animal husbandry production, the large amount of excrement and waste produced in the breeding production process has increased sharply. Due to the general lack of attention to the treatment of cow dung in various places, there are basically no cow dung treatment facilities in some places where cattle are more concentrated, which leads to random dumping and storage of cow dung, especially in summer, where cow dung is piled up. The stench is so strong that it not only has a negative impact on the normal ...
