Embodiment Construction

[0083] A kind of preparation method of ecological fertilizer of the present invention, comprises the steps:

[0084] (1) Mix organic substances containing carbon elements with inorganic substances containing nitrogen and phosphorus elements to make mixed materials;

[0085] Organic matter includes crop stalks, excrement from aquaculture, industrial organic waste and slag, plant withering matter or urban waste.

[0086] Inorganic substances include urea, ammonium bicarbonate, superphosphate or rock phosphate.

[0087] After mixing the inorganic elements and organic substances, the carbon-to-nitrogen ratio is 5-20:1; the carbon-phosphorus ratio is 8-30:1, which can be selected according to different requirements for nutrient enrichment.

[0088] (2) Add composite microorganism A, stir evenly, the water content reaches 50%-60%, hold hands into a ball, and it is advisable to see water between the fingers without dripping; the composite microorganism A is bacillus, lactic acid bac...

Abstract

The invention provides a preparation method of an ecological fertilizer which is ecological and environment-friendly and rich in organic nutrient elements. The preparation method comprises the following steps: (1) mixing an organic substance containing a carbon element with inorganic raw materials containing nitrogen and phosphorus elements to prepare a mixed material; (2) adding composite microorganism A, uniformly stirring, wherein the water content is 50-60wt%, the microorganism A is one or a plurality of bacillus, lactobacillus, saccharomycetes and actinomycetes, the viable organism content is not less than 1billion/g; (3) biologically fermenting; (4) drying the mixed material obtained in the step (3) at low temperature; (5) adding composite microorganism B in the low-temperature dried material, stirring and mixing; (6) pelletizing the mixed material obtained in the step (5) to obtain the ecological fertilizer; and (7) packing the ecological fertilizer prepared in the step (6) and storing.

Description

technical field [0001] The invention relates to a fertilizer preparation method, in particular to a preparation method of an ecological fertilizer enriched with organic nutrient elements. Background technique [0002] In the past 30 years, with the emergence of the theory of inorganic chemical agriculture, a large amount of nitrogen, phosphorus, and potassium elements have been added to the soil, which has changed the lack of three elements in the soil and significantly increased the agricultural output per unit area. It has changed the current situation of shortage of food resources, alleviated the contradiction of food shortage in history, and played a role in promoting the development of the entire economy. The theory of inorganic agriculture holds that the relationship between plants and the absorption of organic substances is broken, and organic nutrients must be mineralized, gasified, chemicalized and inorganicized before they can be absorbed by plants. Under the guid...
