Organic fertilizer prepared from recovered wastes of pig farm and preparation method thereof

Abstract

The invention discloses an organic fertilizer prepared from recovered wastes of a pig farm and a preparation method thereof. The method comprises the following steps: preparing lichens, mellea armillaria sporophore, stillage, yeast powder, cake pulp, brown sugar, honey and a proper amount of water; after mixing and stirring the raw materials, putting the raw materials in a culture barrel and placing the barrel in a darkroom in a semi-hermetical manner, wherein the culture temperature is 20-30 DEG C, and after 15 days when suspended solids immerse to water, the liquid is brown and the pH value is bellow 3.8; adding pig manure, pig urine, pig bone, pig hair, pig blood, horseshit, straws, wheat straws, beanstalks, peanut stalks, copperas and magnesium sulfate into the liquid; after uniformly smashing and stirring, carrying out anaerobic fermentation at an environmental temperature of 20-30 DEG C for 10-20 days in summer and 15-30 days in winter; and smashing, prilling and drying. The organic fertilizer prepared from recovered wastes of the pig farm disclosed by the invention solves the problem of environmental pollution caused by the wastes, soil hardening caused by chemical fertilizers used on soil and unabiding fertilizer efficiency.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and particularly relates to an organic fertilizer prepared by recycling pig farm waste and a preparation method thereof. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, people's demand for meat, eggs and milk has gradually increased, which has led to the rapid development of my country's breeding industry. According to the latest report of the United Nations Food and Agriculture Organization, at the end of May 2013, the number of live pigs in my country reached 530 million. The rapid development of the breeding industry has played a great role in improving the lives of urban and rural people and increasing the income of farmers, but the pollution of the environment caused by the waste of pig farms is also becoming more and more serious. Sustainability of the pig industry. [0003] ...

AI Technical Summary

Problems solved by technology

The rapid development of the breeding industry has played a great role in improving the lives of urban and rural people and increasing the income of farmers. However, the problem of environmental pollution caused by waste from pig farms is becoming more and more serious. If effective measures are not taken to solve it, it will have a serious impact on the environment. Sustainable Development of Pig Industry

[0003] According to the survey, most of the pig farms now have little awareness of the disposal of waste such as pig manure. Most of them are sold directly without treatment, or simply fermented and used as agricultural fertilizers. The pig manure treated in this way is not fermented completely. Not only the odor cannot be removed, the fertilizer effect is not good, but also it will cause ammonia damage to the crops

At the same time, my country is a large agricultural country, and the demand for fertilizers is constantly increasing, and the requirements for fertilizers are also constantly increasing. The chemical fertilizers prepared by chemical agents show disadvantages, which makes the soil harden, the fertility is not durable, and land-borne diseases appear.

In the prior art, the method of fermenting organic fertilizers with livestock manure mostly adopts the purchase of starter products such as EM bacteria agent, the strains are fixed, the content of each element cannot be effectively controlled, and the cost is also high
