Special bio-organic fertilizer using DDGS as a main material for tobacco fermentation

Abstract

The invention relates to a special bio-organic fertilizer using DDGS as a main material for tobacco fermentation. The special bio-organic fertilizer comprises the following raw materials in parts by weight: 67-81 parts of DDGS, 10-14 parts of rapeseed cake, 10-14 parts of biogas residue, 1.5-2.5 parts of mother liquor, 0.05-0.15 part of nutrient element, 0.06-0.1 part of amino acid, 1.5-2.3 partsof humic acid, 0.01-0.02 part of medium trace element, 0.05-0.2 parts of heat-resistant enzyme, 0.05-0.1 part of thermophilic microbial inoculum, 0.3-0.7 part of ammonium sulfate and 1-2 parts of branpowder. the special bio-organic fertilizer has the beneficial effects that the special bio-organic fertilizer for the fermented tobaccos is high in fertilizer efficiency, long in fertilizer efficiency and comprehensive in fertilizer efficiency; the fertilizer has the high activity and long-term effect of organic fertilizers and biological fertilizers, and also has the fast-acting property of inorganic fertilizers and the special effect of microelement fertilizers and bacterial fertilizers, has complete nutrient elements required by plants, and is scientific in proportion. The beneficial biological strains in the special tobacco fertilizer produced by the invention can accelerate rapid cyclic decomposition of substances, release of various nutrient elements, nitrogen fixation, phosphate solubilization and potassium solubilization, promote photosynthesis of plants, and greatly improve the utilization rate and fertilizer efficiency of the fertilizer.

Description

technical field [0001] The invention belongs to the field of preparation of special fertilizer for tobacco, and in particular relates to a bio-organic fertilizer special for fermented tobacco with DDGS as the main material and a preparation method thereof. Background technique [0002] After the common fertilizer is applied to the cultivated land, part of it will be transpired, dissipated and lost with water, part of it will be fixed and utilized by the soil and soil microorganisms, and only part of it will be absorbed and utilized by the crops. Studies have shown that: the utilization rate of urea and ammonium bicarbonate is 20% to 46%, phosphate fertilizer (diammonium, monoammonium, heavy calcium) is 10% to 25%, and potassium fertilizer is 45% to 60%. It can be seen that the utilization rate of ordinary fertilizers is very low. [0003] Tobacco needs to absorb more nutrients in a growth cycle, not just nitrogen, phosphorus, and potassium provided by ordinary fertilizers. ...
