Abstract
Description
Technical Field
[0001] This utility model relates to the field of earthworm farming technology, specifically a composite earthworm bed. Background Technology
[0002] Existing earthworm beds mainly use boxes as containers and use dry straw, filter mud, cow dung or pig manure as raw materials for layered earthworm farming.
[0003] For example, the invention patent with patent publication number CN103070140A discloses an earthworm breeding bed, which is constructed by building a rectangular frame bed with dense and uniform ventilation holes on the four walls and bottom. The earthworm breeding bed is divided into four layers from bottom to top: a dry straw layer, a lower filter mud layer, a cow dung or pig dung layer, and an upper filter mud layer. The bottom is raised to realize earthworm breeding.
[0004] However, this type of tiered box farming has its drawbacks. The scale of farming is limited by the box structure, and the types of earthworms farmed are limited to earthworms used to treat the sludge left over from urban sewage treatment plants. In addition, the heat preservation effect of this tiered distribution is poor, and machine heating is often used for temperature control.
[0005] For example, the Chinese utility model patent CN216722765U discloses "a multifunctional earthworm bed", which achieves temperature control by setting a heating unit at the top of the metal box. However, this method consumes too much electricity; therefore, an environmentally friendly, energy-saving, and temperature-controlled composite earthworm bed is needed. Utility Model Content
[0006] The purpose of this invention is to provide a composite earthworm bed to solve the problems mentioned in the background art.
[0007] This utility model can be achieved through the following technical solutions:
[0008] A composite earthworm bed includes an earthworm habitat area and an external enclosed area. The earthworm habitat area includes a bottom soil layer, and above the soil layer are a weed layer, a cow dung layer, and a branch layer. The external enclosed area includes a film and a shade cloth. The soil layer is based on a field as a base. The upper branches of the branch layer are trimmed flat and in contact with the film, and the lower branches of the branch layer are removed and laid flat on top of the cow dung layer. The film is used to seal and insulate the earthworm bed, and the shade cloth is used to prevent direct sunlight.
[0009] A further technical improvement of this utility model is that the weed layer is a mixture of rice husks and coarse bran, and the thickness of the weed layer is 5 cm.
[0010] A further technical improvement of this utility model is that the branch layer is made up of alternating orange branches, pine branches and maple branches.
[0011] A further technical improvement of this utility model is that the film is made of soft, tough, and wear-resistant polyethylene material.
[0012] A further technical improvement of this utility model is that the light-blocking cloth is woven from plant fibers and completely covers the earthworm habitat.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention adopts a flat, layered method for earthworm farming, which effectively solves the limitations of existing earthworm bed farming technology in terms of earthworm farming scale and earthworm farming types; by covering it with a thin film and a light-blocking cloth, the cow manure layer can ferment better, thereby achieving temperature control, energy saving and environmental protection.
[0015] Using farmland as a base, multiple gaps are created by layering tree branches to allow oxygen to enter, thus expanding the scale of earthworm farming while greatly controlling costs. Secondly, using a variety of raw materials for layering increases environmental diversity and expands the options for earthworm farming types. Attached Figure Description
[0016] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0018] In the diagram: 1. Soil layer; 2. Weed layer; 3. Cow dung layer; 4. Branch layer; 5. Film; 6. Shading cloth. Detailed Implementation
[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0020] Please see Figure 1As shown, this utility model provides a composite earthworm bed, including an earthworm habitat area and an external enclosed area. The earthworm habitat area includes a bottom soil layer 1, with a weed layer 2, a cow dung layer 3, and a branch layer 4 arranged sequentially above the soil layer 1. The external enclosed area includes a film 5 and a shading cloth 6. The soil layer 1 uses a field 20-30 meters long and 1.5-2.0 meters wide as its base, not limited to the limitations of a breeding box. The soil in the soil layer 1 provides a suitable habitat for earthworms. The weed layer 2 provides food for earthworms, and the organic and inorganic matter produced by the microorganisms in the soil layer 1 provides nutrients for earthworms and improves soil fertility, providing favorable conditions for subsequent earthworm growth and reproduction. The cow dung layer 3 provides food for earthworms, and the soft and absorbent nature of cow dung provides a good habitat and suitable humidity for earthworms. The branch layer 4 provides food for earthworms. The separation between the earthworm habitat and the enclosed external area prevents the film 5 and the shading cloth 6 from being too close to the cow dung layer 3, which would lead to air scarcity, hindering the growth and reproduction of earthworms, and providing sufficient above-ground space for earthworms. At the same time, the organic and inorganic matter produced by the decomposition of branches by microorganisms in the soil layer 1 provides nutrients for earthworms and improves soil fertility, providing favorable conditions for subsequent earthworm growth and reproduction. The upper branches of the branch layer 4 are pruned to 50 cm, with the pruned ends kept flat and in contact with the film 5, and the lower branches of the branch layer 4 are removed and laid flat on the upper layer of cow dung layer 3. The film 5 is used to seal and insulate the earthworm bed, preventing rain, water and nutrient loss, and also provides insulation, providing a humid and warm environment for earthworms and preventing them from hibernating. The shading cloth 6 is used to prevent direct sunlight from causing water loss or a sharp rise in temperature, providing a suitable dark environment for earthworms.
[0021] Among them, the weed layer 2 is a mixture of rice husks and bran, and the thickness of the weed layer 2 is 5 cm.
[0022] The branch layer 4 uses orange branches, pine branches and maple branches arranged alternately, using branches with different compositions. After being degraded by microorganisms in the soil layer 1, they provide different nutrients.
[0023] The film 5 is made of soft, tough, and wear-resistant polyethylene material to prevent the film 5 from being punctured when it comes into contact with the tree branch layer 4.
[0024] The blackout cloth 6 is made of plant fiber and completely covers the earthworm habitat, leaving a certain edge for fixation.
[0025] This invention employs a flat, layered method for earthworm farming, effectively overcoming the limitations of existing earthworm bed farming technologies in terms of scale and types of earthworms. By covering the earthworm bed with a thin film 5 and a light-blocking cloth 6, the cow manure layer 3 is allowed to ferment better, thereby achieving temperature control, energy conservation, and environmental protection. Using a field as a base, a layer of tree branches 4 is used to create a multi-gaps space, allowing oxygen to enter. This expands the scale of earthworm farming while greatly controlling costs. Furthermore, the use of multiple raw materials for layering increases environmental diversity and expands the selection of earthworm farming types.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
