Pure natural multi-element organic fertilizer and preparation method thereof

Abstract

The invention discloses a pure natural multi-element organic fertilizer and a preparation method thereof. In the preparation method, the pure natural multi-element organic fertilizer is produced on a large scale by taking leftover furfural residues generated in a furfural plant, leftover spent mushroom compost generated by planting mushrooms, side product plant ash generated in a biomass generating plant and medicinal material dregs generated in a pharmaceutical factory as main raw materials, and adding an organic fertilizer fermenting agent for curing at a high temperature. The organic fertilizer produced by using the method has the advantages of high efficiency, low cost, high nutrition and stable quality, the problems of waste recovery, energy saving and emission reduction can be solved, soil biological balance can be improved simultaneously, and a series of agricultural problems such as soil hardening, salinization, acidification and the like caused by long-term use of a chemical fertilizer are solved. The technical indexes of the pure natural multi-element organic fertilizer produced by using the method are fully accordant with the requirements of more than or equal to 5 percent of nitrogen-phosphorus-potassium and more than or equal to 45 percent of organic matters in the novel organic fertilizer standard NY525-2012 implemented by the National Department of Agriculture in 2012.

Description

Technical field: [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a pure natural multi-component organic fertilizer and a preparation method thereof. Background technique: [0002] According to statistics, my country has 1.44 billion mu of cultivated land, 34 million mu of garden land, and a population of about 1.4 billion. This means that my country needs to use 7% of the world's arable land to feed 22% of the world's population, which forces my country's agriculture to rely on continuous development, that is, sustainable development. In my country, due to the long-term application of chemical fertilizers for many years, although the output of agricultural products has been greatly improved, due to the shortage of organic fertilizers and the imbalance of various nutrients, the ecological environment of farmland, soil physical and chemical properties and soil microbial flora have been affected to varying degrees.

Problems solved by technology

In my country, due to the long-term application of chemical fertilizers for many years, although the output of agricultural products has been greatly improved, due to the shortage of organic fertilizers and the imbalance of various nutrients, the ecological environment of farmland, soil physical and chemical properties and soil microbial flora have been affected to varying degrees. Destruction, to a certain extent, affects the safety of agricultural products and pollutes water sources

Even if organic fertilizers are used in some places, most of these organic fertilizers are produced by traditional composting methods. Composting takes a long time, has low fertilizer efficiency, pollutes the environment, is inconvenient to use, and is not fully decomposed. The main source of infection of the disease will cause problems such as burning roots and seedlings
