Method for processing pig manure with earthworms

Abstract

The invention relates to a method for processing pig manure with earthworms. The method comprises the steps of: establishing a foundation surface of an earthworm biological processing bed, and stacking an earthworm living matrix on the foundation surface, wherein the living matrix is divided into large and small rows for inoculating the earthworms, the input quantity of the living matrix is 0.5-1.5 kg / m<2>, and a shading screen is covered behind a surface layer of the matrix after the earthworms are inoculated; putting the pig manure into an opening container, adding water into the container,and fully mixing to make the pig manure be subjected to anaerobic fermentation, until the pig manure becomes black brown; adding the cured pig manure on a long-strip stack of the earthworm biologicalbed, wherein the added thickness is 2-5 cm; and immediately feeding material when 60-70% of the pig manure is digested, and repeating the steps. The defects that a great number of stench, environmental pollution, easily-generated house fly larvae and the like exist in a past fermenting and pile-turning process are overcome. The pig manure is safely processed with the earthworms, the earthworms are prevented from escaping and dying, no stench is generated, environment friendliness and safety are realized, and the digestion efficiency is high; and by adopting the method provided by the invention, the average daily pig manure consumption is 2-3 times the weight of the earthworms.

Description

technical field [0001] This patent belongs to the technical field of biological treatment of agricultural solid organic waste, and in particular relates to a method for treating pig manure by using earthworms. Background technique [0002] Earthworm breeding technology has been relatively mature at home and abroad. The success or failure of earthworm farming and the quality of feed production play a key decisive role, and the speed of earthworm reproduction depends to a large extent on the quality of feed. All kinds of livestock and poultry manure, such as cow manure, horse manure, pig manure, chicken manure, etc., can be swallowed by earthworms after reasonable preparation and aerobic fermentation. [0003] Before the present invention, it is generally necessary to add a large amount of carbon regulators to the existing livestock and poultry manure to prepare earthworm feed, and the time of aerobic fermentation is generally more than 30 days, and at the same time, it needs ...

AI Technical Summary

Problems solved by technology

The traditional earthworm feed preparation and decomposing process requires a considerable space, and also requires a lot of labor and time, which increases the cost of earthworm farming, and will produce a lot of odor during the fermentation and turning process, which seriously pollutes the environment

Moreover, pig manure has the disadvantages of strong odor and easy growth of fly maggots. When directly feeding earthworms, earthworms cannot swallow them, which often causes a large number of earthworms to escape and die.
