Wet composting method for livestock and poultry dung and waste meat rare-earth selenium-enriched composite organic fertilizer

Abstract

The invention discloses a wet composting method for a livestock and poultry dung and waste meat rare-earth selenium-enriched composite organic fertilizer. The wet composting method comprises the following five process steps: making an organic fertilizer wet composting formula, preparing raw materials, processing raw materials, performing organic fertilizer wet composting, and airing and packaging the organic fertilizer. The made organic fertilizer wet composting formula comprises 150kg / mu of livestock and poultry dung, 50kg / mu of waste meat, 200g / mu of agricultural rare earth, 20g / mu of agricultural selenium fertilizer and 1kg / mu of culture; preparing the raw materials; calculating the purchased amount of the livestock and poultry dung, waste meat, agricultural rare earth, agricultural selenium fertilizer and culture according to the formula ratio; performing raw material processing, namely grinding the livestock and poultry dung by using a screen grinder with the particle size of 0.5cm for later use; adding waste meat dices into a sealed boiling water pot for sterilizing, disinfecting and cooking, pulping into fine meat pulp, and adding water to be diluted for later use; performing organic fertilizer wet composting, namely filling mixed raw materials into a fermentation chamber in a layered manner (with a patent number of 201620301801.6), enabling the thickness of each layer to be 30-40cm, regulating a temperature controller to perform rapid fermentation at a high temperature of 70 DEG C and a low temperature of 60 DEG C, thereby completing the operations within 7-10 days after fermentation.

Description
