Application of fungus dreg serving as granulation binder for producing compound fertilizers and preparation method of granulation binder

Abstract

The invention relates to an application of fungus dreg as a granulation binder for producing compound fertilizers and a preparation method of the granulation binder, i.e. an application of fungus dreg waste (after culturing Agaricus bisporus in a culture medium) serving as a granulation binder for compound fertilizers. In the preparation process, the selected fungus dreg comprises 65-75% of latosolic red soil, 20-30% of organic matter straw and cattle manure and 4-6% of regulator. The preparation method comprises the following step: adding the regulator for carrying out working procedures of yarding fermentation, pulverizing and the like to obtain the granulation binder. The pH value after fermentation is 7.2-7.5, the water content is 15-20%, and the degree of fineness is 100-120 meshes. According to the idea of cyclic economy, the invention uses Agaricus bisporus dreg as the granulation binder used for various compound fertilizers. The granulation binder not only can replace the existing common binders, such as kaolin, rock powder and the like, but also can increase the available nutrient and organic content in the fertilizers, thereby being beneficial to treating pollution, saving cost and enhancing soil fertility.

Description

(1) Technical field [0001] The invention relates to a production technology of a binder for fertilizer granulation, in particular to the application of the bacteria residue (waste) after cultivating Agaricus bisporus as a binder for producing compound fertilizer granulation and its application. Preparation. (2) Background technology [0002] The output and export earnings of edible fungi in Fujian Province have ranked first in the country for more than 20 consecutive years, and the output of Agaricus bisporus accounts for about 16-20% of the total amount of edible fungi. The output of Agaricus bisporus edible fungus produced in other provinces of the country is also considerable. Although some of the fungus residues in the production process of Agaricus bisporus edible fungus are directly returned to the field for use as farmyard manure, the utilization rate is low, and most of the fungus residues are discarded as waste, which not only causes waste of resources, but also ha...

Problems solved by technology

Although some of the fungus residues in the production process of Agaricus bisporus edible fungus are directly returned to the field for use as farmyard manure, the utilization rate is low, and most of the fungus residues are discarded as waste, which not only causes waste of resources, but also harms the environment. more serious pollution

Although there are some companies that produce bacterial residue fertilizers, they are limited to organic fertilizers or organic-inorganic compound fertilizers, and the soil covered with bacterial residues must be separated and discarded first. The process is cumbersome, the utilization rate is extremely low, and it still pollutes the environment.
