Tobacco bio-organic fertilizer using natural extract waste residues as raw materials, preparation method and application of fertilizer

Abstract

The invention provides a tobacco bio-organic fertilizer using natural extract waste residues as raw materials, a preparation method and an application of the fertilizer. The raw materials respectivelycomprise the following components in percentage by weight: 30-35% of apple residues, 35-45% of pear residues, 10-15% of red date filter residues, 5-8% of wheat bran, 0-5% of stevia rebaudiana filterresidues, 5-8% of livestock manure and 1-2% of a composite microbial agent special for crude fiber degradation. The method includes the steps of waste residue pretreatment, mixing, preliminary temperature rise degradation, high temperature decomposition treatment, biological safety evaluation and the like, wherein each index of the organic fertilizer prepared by this method is better than NY 884-2012 standard issued by the state. The organic fertilizer prepared by the method has no obvious impurities, is uniform in size and brown, is beneficial to the growth and development of crop roots and promotes yield increase, and is especially suitable for tobacco planting to use fertilizers. The method changes the waste residues of the extract into valuables, and has good economic benefits and ecological benefits.

Description

technical field [0001] The invention relates to a resource utilization method of tobacco extract waste residue, which belongs to the technical field of tobacco, in particular to a tobacco bio-organic fertilizer using natural extract waste residue as a raw material and its preparation method and application. technical background [0002] Tobacco extracts are aromatic substances extracted from flowers, leaves, fruits, roots and other parts of plants through distillation, extraction, pressing, and adsorption methods. Natural plant extracts are added to tobacco as spices, which can increase the sweetness, Reduce miscellaneous gas, reduce irritation, moisturize, improve aftertaste, reduce harm and other sensory effects. [0003] In recent years, with the large-scale development and application of natural extracts for tobacco, the variety and quantity have continued to increase, and the problem of waste residue treatment of natural extracts has become increasingly prominent. The a...

AI Technical Summary

Problems solved by technology

There are also reports of using waste residues to prepare organic compound fertilizers, but the general addition ratio is no more than 50%. The natural extract waste residues have high solvent content (80%), high crude fiber content (12%), low pH value into acidity, and poor air permeability. These are the key factors hindering the preparation of bio-organic fertilizer

The optimum humidity for the preparation of organic fertilizer by microbial fermentation is 55-65%, and the optimum pH value is 7.5-8.5. The acidic environment directly hinders the growth of microorganisms or even inactivates them; most fermentation strains are aerobic Materials with poor air permeability are difficult to achieve the goal of rapid microbial reproduction and efficient fermentation
