Description
Technical Field
The invention relates to the technical field of cultivation waste treatment and biological fertilizer manufacturing, in particular to an environment-friendly livestock and poultry manure high-temperature aerobic fermentation chamber.
Background
The fertilizer is a substance which provides one or more mineral elements necessary for plants, improves the soil property and improves the soil fertility level, and is one of the material bases of agricultural production. The compound fertilizer produced in China at present is mainly prepared by compounding chemical fertilizers such as nitrogen, phosphorus, potassium and the like, and has the defects that after the compound fertilizer is used for a long time, the condition of plant diseases and insect pests of crops is aggravated, weeds grow transversely, the environmental pollution is serious, the soil ecological imbalance of the cultivated crops is caused, the soil hardening phenomenon is caused, and the like, so that the sustainable development of modern agricultural industry in China is restricted. In order to improve the adverse conditions, the bio-organic fertilizer is produced.
At present, pollution of livestock and poultry breeding industry in China becomes one of the main reasons for deterioration of the ecological environment in rural areas in China, and sustainable development of the national economic environment is severely restricted. China is a big breeding country, and correspondingly produced livestock and poultry pollution is in high risk and serious inconsistency of national environmental self-care. Pollution of livestock and poultry has largely influenced the environmental quality of soils, water bodies and the atmosphere. According to the statistics of the world health organization, 70% of human diseases are derived from animals and mainly from artificially bred animals such as chicken, pigs, ducks, cattle and sheep; the food and agriculture organization of the United nations measures and calculates that 70% of the environmental pollution on the earth comes from the aquaculture industry, and 70% of the environmental pollution on the earth comes from the aquaculture industry for the damage of the atmospheric ozone layer vital to the life of all organisms.
The pollution of the large-scale farms in China is increasingly serious, and the pollution treatment project is put forward by the nation as an important agenda. Along with the enhancement of environmental awareness of people, the country pays more and more attention to environmental pollution, and implements 'turning off and stopping' and strictly executes the enterprises with sewage discharge not reaching the standard. Aiming at the current situation, all places actively act, and the livestock and poultry sewage treatment engineering is increased. The ecological animal husbandry is a necessary way for sustainable development of animal husbandry and contributes to realizing Chinese dreams.
With the continuous growth and development of animal husbandry in China, the environmental protection of the industrial scale is competitive in advance, and the standardization and intensification development of the animal husbandry becomes a necessary trend. The pollution of the breeding industry is becoming the main cause of the deterioration of the ecological environment in rural areas in China, and the pollution of livestock and poultry manure in large-scale farms is also becoming an important component of agricultural pollution.
The biological organic fertilizer is an organic fertilizer containing a certain amount of functional microorganisms, which is prepared by taking livestock and poultry manure, municipal domestic waste, crop straws, agricultural and sideline products and organic wastes generated by food processing as raw materials, matching with a multifunctional fermentation strain agent to quickly deodorize, decompose and dehydrate the raw materials, and then adding a functional microbial agent.
The biological organic fertilizer is a biological soil conditioner, can improve soil fertility, enables the soil to recover normal ecological balance, can increase the content of organic matters in the soil, forms a granular structure, and improves the air permeability, water retention and fertilizer retention performances of the soil, thereby being beneficial to the growth of crop roots, and the biological organic fertilizer can improve and improve the quality and yield of plants. The biological organic fertilizer is nontoxic and harmless, is safe to use, can effectively improve the utilization rate of the fertilizer, decomposes pesticide residues, improves the quality of crops, and negatively produces pollution-free food. On one hand, the bio-organic fertilizer reduces the harm of agricultural products to human bodies and beasts caused by excessive application of chemical fertilizers; on the other hand, inorganic and organic nutrients contained in the bio-organic fertilizer can directly provide crop nutrition, absorption of crops and improvement of quality are facilitated, and the bio-organic fertilizer can enhance activity of soil enzymes. The activity of microorganisms in soil is a fundamental source of soil enzyme formation and accumulation. The content of soil microorganisms is increased, the activities of soil peroxidase, invertase and the like are obviously improved, the decomposition of soil organic matters and the conversion of mineral nutrients are accelerated due to the enhancement of an enzymatic effect, so that the nutrient absorption of crop roots is facilitated, and the plant disease and insect pest resistance of plants can be enhanced by the bio-organic fertilizer.
The biological organic fertilizer can promote the proliferation of beneficial microbes in the rhizosphere of crops and improve the ecological environment of the rhizosphere of crops. Massive propagation of beneficial microorganisms and increase of disease-resistant factors form a dominant population in a plant rhizosphere area, growth and propagation of pathogenic microorganisms are inhibited, and occurrence of crippling pests of plants is reduced: meanwhile, the beneficial microorganisms can induce the plants to generate antibiotic substances and catalase and polyphenol oxidase of the plants, participate in defense reaction of the plants, improve the disease and insect pest resistance of spike substances, reduce the disease index of continuous cropping crops, and can greatly relieve continuous cropping obstacles after being applied in successive years.
However, the common bio-organic fertilizer at present has some defects, such as low retting temperature, incapability of killing harmful bacteria, especially chicken manure, and if the fermentation treatment is not carried out or is incomplete, seedling burning caused by a large amount of urokinase contained in the chicken manure can occur, even grass growth can be caused after long-term use, and serious adverse effects are brought to agricultural production.
