Embodiment Construction

[0026] The present invention is further described in detail below.

[0027] The product prepared by the method of the present invention uses mushroom dregs as one of the main raw materials, which not only makes mushroom dregs available as a nutrient-rich, quick-release substrate, but also can be used as an organic fertilizer for industrial distribution and application; it not only uses mushroom dregs It is used as a fertilizer, and it is also used as a compost additive added in the initial stage of composting, which improves the nutrient release and multiplication effect of composting fermentation. In the case of mushroom slag as a single ingredient in step (1), the experiment found that adding a bio-fermentation agent in advance can increase the crude protein of the mushroom slag material after fermentation by at least 18%, and the degradation rates of cellulose and hemicellulose exceed 26% respectively. %, 31%.

[0028] Under the condition that mushroom dregs and rice straw...

Abstract

The invention discloses a preparation method of an organic fertilizer. The preparation method is characterized by comprising the following steps: compounding: preparing raw materials of the organic fertilizer, mixing a biological starter with the raw materials, and performing uniform mixing; fermentation: implementing aerobic fermentation on the configured raw materials to generate spawns, and then performing stacking and anaerobic digestion for compost, wherein a mixed material subjected to fermentation contains greater than or equal to 80% of an organic matter, greater than or equal to 8% of NPK, greater than or equal to 5% of amino acid and greater than or equal to 0.21 g / kg of bio-fungus; curing: enabling the mixed material subjected to the fermentation step (2) to enter a curing plant, stabilizing ingredients, then enabling the product to enter a production plant, and performing breaking and screening, wherein the diameters of the screened materials are smaller than 10 mm; granulation: extruding and granulating the mixture by a granulator, and then, performing low-temperature drying to produce the organic fertilizer. The preparation method has the following advantages: the organic fertilizer produced by the process is suitable for serving as fertilizer concentrates for planting matrices and various plants, and is suitable for large-scale industrial processing of mushroom residues and animal and plant organic raw materials.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a preparation method of organic fertilizers. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. One of the material basis of agricultural production. As early as the Western Zhou Dynasty, China already knew that field weeds can promote the growth of millet after they rot. "Qi Min Yao Shu" introduces in detail the method of planting green manure and the method of crop rotation between leguminous crops and gramineous crops; it also mentions the method of using crop stalks mixed with cow dung and urine, trampling and composting to make fertilizer . However, the fertilizers widely used in traditional vegetables and fruit trees often affect the taste and appearance of vegetables and fruits. [0003] Organic fertilizers are rich in organic matter and nutr...
