Biomass organic fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of comprehensive utilization of biomass organic fertilizers, and particularly relates to a biomass organic fertilizer which is prepared by processing a solution A obtained by taking an animal manure protogenetic solution such as human or livestock, a plant raw material B obtained by collecting stems, stems or leaves of plants such as rice, wheat, sugarcane and corn, and a proper amount of quick lime, and the weight ratio of the solution A to the plant raw material B to the quick lime is 65: 30: 5. According to the invention, not only is recycling of the straws and the livestock and poultry manure realized, but also the straws and the livestock and poultry manure can be used for producing electricity, heat, cold, biogas and organic fertilizers after being treated, so that the resource utilization of the straws and the livestock and poultry manure is improved. Internal circulation of electric power and heat energy is achieved, comprehensive benefits and economic benefits of environmental protection can be greatly improved, and recycling and harmless utilization of straw is achieved. Through biomass energy electric heating cold air fertilizer poly-generation integration, a terminal product with large market potential and demand is formed, a biomass industry chain is expanded, and green and healthy development of the biomass industry is promoted.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of biomass organic fertilizers, in particular to a biomass organic fertilizer. Background technique [0002] There are a large number of livestock and poultry farms in my country, and the amount of animal carcasses or feces produced is relatively large. A large amount of waste materials cannot be effectively controlled, and a large part of them is discharged randomly, seeping into fields or rivers, polluting people's living environment. Moreover, our country has not issued a clear policy to manage the excrement and waste of such livestock and poultry farms, so there has been a situation of disordered management of many breeding units. There are also many traditional ways to treat livestock and poultry manure, such as using it as fertilizer, as feed, or other natural biological treatment methods and so on. It's just that the feasibility and practical benefits of these methods are...

Problems solved by technology

Although returning to the field is an effective way to reduce the amount of biogas slurry, due to the complex composition of the biogas slurry, the use of returning to the field is also affected by many factors such as land carrying capacity and seasonal changes, resulting in that the biogas slurry cannot be fully absorbed. Further harmless treatment

[0004] Livestock and poultry manure will pollute the soil, environment, and air. The following problems will exist in the treatment of livestock and poultry manure: ①Livestock and poultry manure contains a large number of bacteria, fungi, sporophytes, and some of them also contain viruses and parasites, which are harmful to livestock and poultry. If the treatment of poultry manure is not in place, it is easy to pollute the water source, soil and the air in the farm, causing the spread of pathogens; ②Most livestock and poultry feed contains heavy metal elements such as iron, copper, zinc, and manganese. It cannot be completely absorbed and utilized by livestock and poultry, and will be excreted when livestock and poultry excrete feces and urine. These metal elements will cause serious pollution to water and

③Due to the different absorption and utilization of antibiotics by livestock and poultry, and the lack of professional knowledge of some farmers, antibiotics are abused, resulting in some antibiotics being excreted with the excretion of livestock and poultry

[0005] In order to solve the problems of low utilization rate of biomass resources and environmental pollution caused by livestock and poultry manure, technical improvement and innovation are needed
