Description

A kind of multifunctional microbial organic fertilizer and preparation method thereof

1. Technical field

The invention relates to a biological fertilizer used in the process of plant growth, in particular to a multifunctional microbial organic fertilizer and a preparation method thereof.

2. Background technology

Due to the over-exploitation of my country's agriculture, especially the long-term partial application of chemical fertilizers, there is no proper supplement of agricultural organic matter to the soil, resulting in the decline of soil quality, the gradual depletion of available agricultural resources, and serious soil degradation, which ultimately affects the production of high-quality agricultural products. The current status of soil resources in my country urgently needs artificial measures to supplement soil agricultural organic matter to ensure the level of agricultural planting and the quality of crop products. Corresponding to this situation, the development and promotion of organic fertilizer technology in my country is relatively backward. There are very few products and organic fertilizer manufacturers to choose from on the market. For example, Heilongjiang Province is the main province of my country's rice export. Over the years, the most troublesome problem encountered by the provincial grain export department is that batches of exported rice are often returned by foreign quality inspection agencies. The problem is that the quality of rice cannot meet the requirements of importing countries due to the long-term use of large amounts of chemical fertilizers and pesticides in the production process. In addition, with the increase of crop planting years, a large number of harmful organisms have accumulated in the soil, the occurrence of diseases has become more and more serious, the soil has a large amount of compaction, and the fertility and tillage power have decreased, which eventually leads to a significant decline in crop yield and quality. Therefore, soil fertility decline and soil-borne diseases have become important limiting factors affecting crop production and quality. With the gradual improvement of people's living standards and the upgrading of consumption concepts, the increasing demand for green products and the country's requirements for energy saving and consumption reduction, the development of green and environmentally friendly microbial organic fertilizers has become the mainstream of current social development. However, at present, most of the fermentation of microbial organic fertilizers adopts aerobic fermentation, which needs to continuously stir and aerate the compost during fermentation, resulting in the leakage of stench during the fermentation process, seriously polluting the environment and the health of operators, and increasing the cost of equipment , energy costs, labor costs. In summary, in the process of researching the present invention, the inventor finds that the following problems exist in the production of microbial organic fertilizers at present:

1. At present, aerobic microorganisms are mostly used in the fermentation of microbial organic fertilizers. Therefore, ventilation and oxygen supply are required during the fermentation process, and multiple turning and stirring operations are required. In addition, stench will be generated during the operation process, and sewage cross-flow will occur, resulting in energy loss. Waste, increase equipment cost;

2. The microbial organic fertilizer produced often has a certain effect on improving soil fertility and soil structure, but the effect on disease control is relatively poor, especially for soil-borne diseases.
