Description

An environment-friendly high-temperature aerobic fermentation chamber for livestock and poultry manure

technical field

The invention relates to the technical field of breeding waste treatment and biological fertilizer production, in particular to an environment-friendly high-temperature aerobic fermentation chamber for livestock and poultry manure.

Background technique

Fertilizer is a kind of substance that provides one or more essential mineral elements for plants, improves soil properties, and improves soil fertility. It is one of the material basis of agricultural production. At present, the compound fertilizers produced in our country are mainly composed of nitrogen, phosphorus, potassium and other chemical fertilizers. The disadvantage is that after long-term use, it will not only aggravate the pests and diseases of crops, but also cause weeds to grow wildly and cause serious environmental pollution. , make the soil ecological imbalance of cultivated crops, cause soil compaction and other phenomena, and restrict the sustainable development of my country's modern agricultural industry. In order to improve these bad conditions, bio-organic fertilizers came into being.

At present in our country, the pollution of the livestock and poultry breeding industry has become one of the main reasons for the deterioration of the rural ecological environment in our country, which seriously restricts the sustainable development of the national economic environment. my country is a large breeding country, and the corresponding output of livestock and poultry pollution is already at a high risk, which is seriously inconsistent with the national environmental protection. Poultry pollution has greatly affected the environmental quality of soil, water and atmosphere. According to the statistics of the World Health Organization, 70% of human diseases and epidemics come from animals, mainly from artificially farmed animals such as chickens, pigs, ducks, cattle and sheep; the Food and Agriculture Organization of the United Nations estimates that 70% of the environmental pollution on the earth comes from the breeding industry, and it is important to all 70% of the destruction of the atmospheric ozone layer for biological life comes from aquaculture.

The pollution of large-scale farms in my country is becoming more and more serious, and pollution control projects have been put on the important agenda of the country. With the enhancement of people's awareness of environmental protection, the country pays more and more attention to environmental pollution. Enterprises that fail to meet the sewage discharge standards will be "shut down and stopped" and strictly enforced. In response to this situation, all localities have taken active actions to increase the livestock and poultry sewage treatment projects. Taking ecological animal husbandry is the only way for the sustainable development of animal husbandry and contributes to the realization of the Chinese dream.

With the continuous growth and development of my country's animal husbandry industry, the competition for industrial scale environmental protection is becoming increasingly fierce, and the standardized and intensive development of animal husbandry has become an inevitable trend. Pollution from the breeding industry is becoming the main reason for the deterioration of the rural ecological environment in my country, and livestock and poultry feces pollution from large farms has also become an important part of agricultural pollution.

Bio-organic fertilizer is made of livestock and poultry manure, municipal solid waste, crop stalks, agricultural by-products and organic waste from food processing, and is mixed with multi-functional fermentation strain agent to make it deodorize, decompose and dehydrate quickly, and then add Functional microbial agent is a processed organic fertilizer containing a certain amount of functional microorganisms.

Bio-organic fertilizer is a kind of biological soil improver, which can improve soil fertility, restore soil to normal ecological balance, increase soil organic matter content, form aggregate structure, improve soil air permeability, water retention and fertilizer retention performance, which is beneficial to crop root system The growth of bio-organic fertilizers can improve and improve plant quality and yield. Bio-organic fertilizers are non-toxic, harmless, and safe to use. They can effectively improve the utilization rate of chemical fertilizers, decompose pesticide residues, improve crop quality, and produce pollution-free food. On the one hand, bio-organic fertilizers reduce the harm of agricultural products to humans and animals caused by excessive application of chemical fertilizers; on the other hand, the inorganic and organic nutrients contained in bio-organic fertilizers can directly provide crop nutrition, which is conducive to the absorption and quality of crops. The improvement of bio-organic fertilizer can enhance the activity of soil enzymes. The activity of microorganisms in the soil is the fundamental source of the formation and accumulation of soil enzymes. The content of soil microorganisms increases, and the activities of soil peroxidase and invertase increase significantly. Due to the enhanced enzymatic effect, the decomposition of soil organic matter and the transformation of mineral nutrients are accelerated, which is beneficial to the absorption of nutrients by the roots of crops. Bio-organic fertilizers can Enhance the ability of plants to resist diseases and insect pests.

Bio-organic fertilizers can promote the proliferation of beneficial microorganisms in the rhizosphere of crops and improve the ecological environment of the rhizosphere of crops. The massive reproduction of beneficial microorganisms and the increase of disease resistance factors form dominant populations in the rhizosphere of plants, inhibit the growth and reproduction of pathogenic microorganisms, and reduce the occurrence of plant lameness and pests: at the same time, beneficial microorganisms can induce plants to produce antibiotics and plant Catalase, polyphenol oxidase, etc., participate in the defense response of plants, improve the ability of crops to resist diseases and insect pests, reduce the disease index of crops in heavy cropping, and apply them year after year, which can greatly alleviate the obstacles of continuous cropping. The beneficial effect of bio-organic fertilizers During the reproduction process, microorganisms secrete a variety of metabolites to the soil, antagonize harmful microorganisms, promote the transformation of nutrients in the soil, improve the effectiveness of soil nutrients, improve the nutritional conditions of crops, and increase soil fertility.

However, there are still some defects in the common bio-organic fertilizers at present, such as low stacking temperature, which cannot kill harmful bacteria, especially chicken manure. And lead to burning seedlings, long-term use may even cause no grass to grow, and bring serious adverse effects to agricultural production.
