Method for rapidly propagating earthworms and producing high-quality earthworm manure by using solid-liquid separated cow dung and manure slurry

Abstract

The invention provides a method for rapidly propagating earthworms and producing high-quality earthworm manure by using solid-liquid separated cow dung and manure slurry. The solid-liquid separated raw cow dung is used to establish an earthworm bed, and I completely irrigated with water before inoculation of earthworms, the manure slurry is poured to the surface of the culture bed in the breedingperiod to consume a waste liquid and increase the nutrition of the matrix, and an ecological refuge island for earthworms is established in a part of a fresh manure slurry-free area in the breeding period to make the earthworms gradually adapt to the manure slurry environment; and earthworm manure and earthworm cocoons are scraped and collected when the surface of the earthworm bed is taken by theearthworms and a large amount of the earthworm cocoons are distributed, earthworm larvae enter a lower layer and continuously produce cocoons, the collected earthworm cocoons and earthworm manure areused to cover a newly established earthworm bed, high-nutrition and high-microbial activity earthworm manure is continuously collected after the earthworm larvae hatch, and the earthworm larvae are cultured until adult earthworms are adult for sales. The method can realize recycling of intensive cattle waste liquid wastes, increase the yield of the earthworms and greatly improve the nutrient index and the microbial index of the earthworm manure, so the purposes of laborsaving mechanical collection and treatment of the cow manure, high earthworm breeding efficiency, resource utilization of nutrient elements, economic benefit maximizing, environmentally friendliness and ecologicalization are achieved.

Description

technical field [0001] The invention relates to the field of vermiculture, in particular to a method for rapidly propagating earthworms and producing high-quality vermicompost by using solid-liquid separation of cow dung and dung slurry. Background technique [0002] With the continuous improvement of the intensification, labor saving, scale and mechanization of the cattle industry, the treatment of livestock manure waste is an urgent problem to be solved, and there will be huge environmental risks if it is not handled properly. Large-scale cattle manure liquid slurry and solid-liquid separation is an important technical measure for manure labor-saving pipeline transportation and subsequent treatment of cow manure, but at present, large-scale cattle farms also have liquid waste treatment after solid-liquid separation Difficulty, potential environmental risks, and ineffective development and utilization of nutritional resources. [0003] Earthworms, commonly known as earthwo...

AI Technical Summary

Problems solved by technology

[0004] Cow dung is the most important and widely used food material for large-scale farming of earthworms. At present, the earthworm farming industry generally uses cow dung collected directly from cattle farms to ferment and use it as earthworm feed to breed earthworms. Some farmers also use directly collected cow dung to pile up. Farming earthworms without fermentation or incomplete fermentation, this kind of cow dung collection and earthworm breeding related technology requires a lot of labor and is not suitable for large-scale cattle farms to deal with a large amount of pulpy cow dung

[0005] The traditional technology and method of breeding earthworms with cow dung continuously feeds earthworms on the upper layer, resulting in the constant elevation of the vermicompost and the inability to separate the vermicompost in time. The vermicompost is only cleaned out once in the last one to two years. The result is vermicompost functional microorganisms The quantity is reduced, which eventually seriously affects the quality of vermicompost
