Embodiment Construction

[0021] Taking the construction and operation of a large-scale earthworm digestion field as an example, the implementation steps are divided into (1) worm bed construction; (2) working worm domestication; (3) earthworm inoculation with fresh cow manure; (4) digestion environment control; ( 5) Daily management.

[0022] First of all, the construction work of the worm bed is carried out.

[0023] The earthworm bed is best built near the water source and has good drainage conditions; the earthworm bed is 20-25 meters long and 3.5 meters wide; the earthworm bed is spaced 50 cm apart in width, and the distance between the earthworm bed and the original surface layer of the earthworm bed is 6 cm. , usually used as a transportation road, and used as a drainage ditch when it rains heavily, and the long-distance interval is used as a drainage ditch. Irrigation and drainage facilities should be prepared near the worm bed.

[0024] Secondly, carry out the domestication of working worms....

Abstract

The invention belongs to the technical field of agricultural solid organic waste biological counteraction, and in particular relates to a method for directly counteracting fresh cow dung through earthworms. The method comprises the following steps: acclimating the earthworms through the mixture of earthworm cast and fresh cow dung; and directly inoculating the earthworms to the fresh cow dung through a stack earthworm cast film covering technology for the biological counteraction of the fresh cow dung. During the whole counteraction process, the method has the advantages that the method has environmental protection and safety without mosquitoes, flies and odor; the working earthworms grow up in good condition with large amount of finished product of the earthworms and eggs; the counteraction efficiency is high, the average amount of the fresh cow dung consumed everyday is 2 to 3 times of the body weight of the earthworms; and each 3-mu field can annually counteract the dung of 100 cows.

Description

technical field [0001] The invention belongs to the technical field of biological digestion of agricultural solid organic waste, is an organic part of the clean production technology of dairy farms, and specifically relates to a method for directly digesting fresh cow dung by earthworms. Background technique [0002] Earthworm breeding technology has been relatively mature at home and abroad. The success or failure of earthworm breeding and the quality of feed production play a key decisive role. The speed of earthworm reproduction is largely determined by the quality of feed. The feed of earthworms is very extensive and can be roughly divided into animal feed, plant feed and garbage feed. Animal feed is cow manure, horse manure, pig manure, chicken manure and other livestock and poultry manure. After various feeds are properly prepared and decomposed, they can form a high-efficiency feed with a reasonable ratio of nitrogen and carbon, rich in nutrients and comprehensive, w...
