Method for producing organic and inorganic compound fertilizer by utilizing duck dropping source

Abstract

The invention discloses a method for producing an organic and inorganic compound fertilizer by utilizing a duck dropping source, which comprises the following steps: regulating C / N ratio and water content of organic wastes; adding a CM fermenting agent to the organic wastes; carrying out aerobic fermentation and secondary fermentation on the organic wastes and then pulverizing the organic wastes; adding large and intermediate trace element chemical fertilizers and a fertilizer regulator or a plant growth regulator to the pulverized organic wastes; and granulating to prepare a commercial organic fertilizer. The invention has simple method, can process the duck dropping source at a time and has flexible nutrient proportioning and strong adaptability of the produced organic fertilizer and obvious fertilizer yield increasing effect.

Description

technical field

[0001] The invention relates to a fertilizer production method, in particular to a method for producing organic-inorganic compound fertilizer by utilizing duck manure resources. Background technique

[0002] With the development of the economy, the livestock and poultry industry has changed from a sideline industry to a main industry, and the ratio of its output value to the large agricultural output value is increasing year by year, exceeding 60%. However, the large amount of excrement produced in the process of livestock and poultry breeding and the problem of environmental pollution caused by the loss of livestock and poultry manure have been placed in front of us very urgently. How to reasonably and effectively use and deal with livestock and poultry has aroused widespread concern and needs to be solved urgently. question.

[0003] Livestock and poultry manure is directly applied as an organic-inorganic compound fertilizer. The biggest obstacle is high w...
