Description
Technical Field
The invention relates to the technical field of fertilizer production, in particular to a preparation method for manufacturing a biological organic fertilizer by using animal wastes.
Background
With the increasing world population, the demand for food is also increasing, and the status of agricultural science and technology development is also more and more important. In the development of agricultural science and technology, fertilizers play a vital role. However, only 20-30% of the chemical fertilizers applied to the soil are absorbed and utilized by the current season crops, and the rest of the chemical fertilizers are fixed by the soil. The long-term application of a large amount of chemical fertilizers causes a series of serious ecological environment problems such as soil acidification, hardening, fertility reduction, over-standard nitrate content of underground water, air pollution, water eutrophication and the like. At present, agricultural cultivated land in China is about 80% deficient in nitrogen, 50% deficient in phosphorus, 30% deficient in potassium, and organic matter of some soil is less than 1%.
The increasing deterioration of environmental problems has led to the recognition of the importance and urgency of protecting the human living environment, and also the recognition that the natural resources available to humans on earth are limited and must be recycled and repeatedly regenerated to achieve sustainable development of the human society. The agriculture needs to go a sustainable development way, and the development of ecological agriculture is a necessary trend, so the development of biological organic fertilizer is also imperative. The development of biotechnology and the penetration of high and new technologies can lead the biological organic fertilizer to have good production and application prospects from the viewpoints of developing sustainable agriculture, organic agriculture and ecological agriculture and developing pollution-free and pollution-free green food production, and from the viewpoints of reducing the use of chemical fertilizers and pesticides, reducing and lowering environmental pollution, lightening the burden of farmers and reducing production cost.
Along with the development of cities, the scale of cities is getting bigger, domestic garbage and excrement excreted by people in daily life become burdens of cities, and straws in some underdeveloped rural areas cannot be effectively treated, for example, the straws are generally treated as garbage, so that manpower and material resources are wasted, land is wasted, and the environment is also polluted, so that organic fertilizers need to be produced in daily life to improve the application of the garbage, wherein the organic fertilizers refer to fertilizers prepared by microbial fermentation, deodorization and decomposition of livestock and poultry excrement, straws, solid wastes of agricultural and sideline products and food processing, organic garbage, municipal sludge and the like.
The organic fertilizer prepared by using the biological manure not only provides plant nutrient elements and trace elements, but also shows the functions of nitrogen fixation, potassium dissolution, phosphorus dissolution, mineral nutrient conversion, nitrogen protection, potassium protection and the like through microbial activities, thereby realizing the improvement of the effective supply amount and the total supply amount of the plant nutrient elements.
An effective solution to the problems in the related art has not been proposed yet.
