Method of preparing fertilizer by fermenting tobacco waste, phosphogypsum and muck

Abstract

The invention discloses a fertilizer preparing method of fermented tobacco waste, phosphogypsum and slurry, which comprises the following parts: 63-69% tobacco waste, 3-6% phosphogypsum, 28-31% slurry, wherein the moisture of organic composite fertilizer is about 70% with even ingredient of N at 0.7-0.8%, P2O5 at 0.38-0.40% and K2O at 0.7-0.8.

Description

technical field

[0001] The invention relates to the field of organic compound fertilizer production, in particular to a method for preparing bio-organic fertilizer by fermenting tobacco waste, phosphogypsum and mud manure. Background technique

[0002] The output of nitrogen fertilizer and phosphorus fertilizer in my country ranks second and third respectively in the world. In order to pursue high yield in agriculture, a large number of chemical fertilizers are used, which has caused soil sandification, compaction, and fertility decline. The main disadvantage of using phosphorus fertilizer or nitrogen fertilizer alone is the fertilizer content. Incomplete, blending and increasing application will cause a sharp increase in the solubility product, and the fertilizer will be easily lost, and the high-yield effect of crops will not be achieved.
