Method for artificially breeding medicinal earthworms in soil pit

Abstract

The invention provides a method for artificially breeding medicinal earthworms in a soil pit and relates to the technical field of culture of special species. The method comprises the steps of excavating the soil pit at a corner behind a house, wherein the depth of the soil pit ranges from 50 cm to 60 cm, laying base materials in the soil pit layer by layer, wherein firstly, a layer of base materials which are 15 cm in thickness are laid on the lowermost layer of the soil pit, then a soil layer which is 8 cm in thickness is laid on the base materials on the lowermost layer, then a layer of base materials which are 15 cm in thickness are laid on the soil layer, finally, a layer of soil which is 5 cm in thickness is laid on the uppermost layer, then placing the Northern Star No.2 red earthworms in the soil pit for breeding, spraying water or moisture retention liquid frequently during the breeding period so that the relative humidity of the base materials can be kept within the range from 60% to 70%, using straw matting to cover the upper end of the soil pit and serve for shading, and controlling the temperature in the soil pit within the range from 23 DEG C to 25 DEG C. The base materials used in the method are good in air and water permeability, survival of the earthworms in the closed environment is guaranteed, and thereby the breeding rate of the earthworms is raised; feed of the earthworms is abundant, and the growth and propagation speed of the earthworms is high. The method is low in breeding difficulty, easy to achieve, small in investment and beneficial to rapid popularization.

Description

technical field [0001] The invention relates to the technical field of special breeding, in particular to a method for artificially breeding medicinal earthworms in an earth pit. Background technique [0002] Artificial breeding of earthworms is an emerging business. It can be used as protein feed for livestock, poultry, fish, etc., can use earthworms to improve soil, cultivate soil fertility, and can also process urban organic waste, turn waste into fertilizer, and eliminate the impact of organic waste on pollution of the environment. Earthworms are widely used and have high economic value. [0003] And the method for the large-scale cultivation of earthworms in existing factories must have certain special-purpose sites and facilities, including feed processing plants, temperature control workshops, breeding beds and the like. The threshold for artificial breeding of earthworms is relatively high, which is not conducive to the promotion of breeding. Contents of the inve...
