Method of preparing bio compound fertilizer

Abstract

The invention discloses the preparation method of a biologic compound fertilizer, which is characterized in that the preparation method comprises the following steps: (1) retting plant and animal residues and animal manure, i.e. fermenting the plant and animal residues and the animal manure; (2) crushing and removing impurities, i.e. crushing and stratifying the retted materials obtained in step (1) to obtain the fine powdered retted materials and transferring to the next procedure; (3) metering and mixing, i.e. mixing the fine powdered retted materials from the above procedure with urea and calcium magnesium phosphate at the ratio of a production formula and blending in a mixing tray; (4) pulverizing each material weighted in the above procedure; (5) mixing the materials obtained in the above procedure completely by a large rotary table, and spraying a bacterial liquid produced by a strain spray room to make the bacterial liquid adhere in the solid material uniformly while feeding and rotating the material; and (6) packaging the product. The preparation method can produce the biologic compound fertilizer capable of effectively improving the soil with high organic matter content, greatly increasing soil aggregate, and combining effects of fast release and slow release; and the investment is small.

Description

Technical field

[0001] The invention relates to a manufacturing method of biological compound fertilizer. Background technique

[0002] Fertilizer is the food of crops, and it is the essential basic production material in agricultural production. However, there are traditional habits and experience in the use of organic fertilizers in agricultural production, and with the development of the market economy, the transportation of farmyard manure is often time-consuming and labor-intensive, so the use of organic fertilizers is constantly decreasing. The production and use of chemical fertilizers in my country has gone through three stages: before the 1960s, it was a low-concentration stage of elemental substances, such as ammonia, ammonium sulfate, ammonium bisulfate, ammonium superphosphate, etc., and the second stage was a high-concentration and compound fertilizer stage after the 1960s. , Such as urea, ammonium phosphate and other high-quality fertilizers, the third stage is the ...

[0037] The manufacturing method of the biological compound fertilizer of the present invention will be further described below:

[0038] 1. Raw materials

[0039] ①Organic base material: all animal and plant residues and animal excrement can be used as raw materials. This patented product uses chicken manure, peat soil, and sugar wood powder from large chicken farms (sugar wood powder, wood powder is a board factory , Wood powder polished by furniture factory wood products, sugar is the auspicious water concentrate of sugar factory sugar) as the main raw material, the three main raw materials each account for 30% of the entire raw material (the remaining 10% are fertilizers: urea, calcium magnesium phosphate fertilizer) And fly ash used as a PH regulator).

[0040] ②Fertilizers: urea and calcium magnesium phosphate fertilizers and fly ash used as PH regulators. Among them, urea accounts for 3 to 4% of the total raw materials, and calcium magnesium phosphate fertilizers account for...
